Disruptive Technologies for 2015: Software-defined Storage, Virtual SAN, Flash and Hybrid Cloud Predictions

George Teixeira
President and CEO, DataCore Software

Major storage hardware vendors saw flat growth or significant sales declines as a result of all the disruptive forces hitting the data storage market this year. Virtual SANs, hybrid clouds, flash for performance and software-defined storage have become the rage but enterprises are still struggling to implement these new technologies in a practical manner.  

Below are four related enterprise software predictions for 2015. 

#1: Software-defined Storage Will Go Mainstream in 2015
The value proposition for Software-defined storage is inevitable. It will continue to disrupt enterprise storage in 2015. It will further commoditize underlying storage devices and raises storage features and services from being locked to those devices. True software-defined storage platforms like DataCore will deliver comprehensive storage services that allow devices to achieve a new level of productivity by being able to work cross-platform and infrastructure-wide.  Bottom-line, the compelling economic benefits, better productivity and the need for greater agility to meet future requirements will drive software-defined storage to become a mainstream solution in 2015.

#2: Hybrid Clouds will become Practical in 2015
Enterprises are dealing with both on-premise storage and off-site cloud storage (hybrid cloud). This will become a bigger issue as customers become smarter about what cloud workloads are practical. On-premise storage is usually allocated for active data such as transaction-oriented business. The cloud will still be primarily used for cold data, back-up and disaster recovery due to internet speeds. New solutions are emerging such as DataCore and Microsoft StorSimple, which combine to allow data (from any storage) to be seamlessly migrated from on-premise to a cloud such as Microsoft Azure. This will fuel the larger trend, which is for enterprises to do a mix of on-premise and cloud. In addition, while doing disaster recovery from the cloud remains complex, new integration tools and more automated processes are on the way to make this a more practical solution.

#3: Disk and flash software stacks must span both worlds. Flash is excellent for specialized workloads that require high speed reads such as databases, but it is not a cost-effective solution for all workloads and still makes up a very small fraction of the installed storage base overall. On the other side of the spectrum are low-cost SATA disk drives that continue to advance and use new technologies like helium to support huge capacities, up to 10 TB per drive, but they are not highly performant and are slow.  Write-heavy transaction workloads also need to be addressed differently. (See New Breakthrough Random Write Acceleration and Impact on Disk Drives and Flash technologies). All flash is still not practical due to the costs involved, and the large installed base of disk storage that must be addressed. Comprehensive software stacks  will rise in importance in 2015, since users must be able to optimize the cost and performance trade-offs and migrate workloads to the right resources needed whether flash or disk. Software-defined storage done right can help unify the new world of flash with the existing and still-evolving world of disks. Both have a future.

#4: Servers as Hyper-converged Virtual SANs will Continue to Displace Traditional Storage Arrays
The latest generation of servers are powerful and will continue to support even larger amounts of storage. Software defined storage software such as DataCore’s Virtual SAN software will further drive servers to be transformed into powerful storage systems and, in effect, enterprise-class virtual SANs.

DataCore's New Random Write Accelerator for Databases,SQL, ERP, OLTP and RAID-5 workloads

DataCore in its most recent release has added even more powerful and comprehensive enterprise-class functionality to its SANsymphony™-V10 storage services platform and its ‘any hypervisor, any storage’ DataCore™ Virtual SAN. The newest enhancements further boost I/O performance and double the scale of hyper-converged storage systems to 64 nodes.  
Accelerate Performance Up to 30X for Random Write Intensive Applications such as OLTP

The new software release includes a new Random Write Accelerator, which yields up to 30 times faster performance for random-write-heavy workloads that frequently update databases, ERP and OLTP systems. Even greater performance gains can be realized on RAID-5 protected datasets that spread data and reconstruction information to multiple locations across different disk drives.
To Learn more, see our webinar series and demo:
SSD-like Speeds from Spinning Disks; Faster Response and Reduced Write-wear for Flash
The remarkable write performance speed-ups are most pronounced when using low-cost spinning disks (e.g., SATA disk drives) where each write incurs significant rotational and seek delays to mechanically update blocks on spinning platters. Higher speed flash-based technologies (SSDs), especially prone to write-amplification and rapid wear, benefit from the Random Write Accelerator as well, delivering up to 3.6 times more IOPS.
Double the Scalability – Hyper-Converged Systems up to 64 Nodes and Over 100 Million IOPsThe new version of DataCore Virtual SAN supports larger scale configurations that can be managed centrally and organized to match business operational needs. With these latest enhancements, customers can now spread their workloads over more servers in a cluster and share resources across multiple clusters in order to improve their response and throughput. 
Doubling the possible number of nodes in a DataCore Virtual SAN is particularly valuable for latency-sensitive applications distributed over large-scale clusters, as well as virtual desktop (VDI) deployments for thousands of users.

Scaling out the configuration across more nodes enables better distribution of the workloads and segmentation of the physical storage capacity. DataCore’s zero-touch failover capabilities ensure workloads and applications are not disrupted in the event of a node or storage failure. The internode mirrors can also be stretched over metro-wide distances up to 60 miles (100 kilometers) to improve overall availability and business continuity. Scaling out to more nodes also enhances the overall resiliency of the infrastructure.

Press Release: 

DataCore Introduces Major Breakthroughs in Performance, Scalability and Quality of Service in its New Software-Defined Storage and Virtual SAN Release

Wednesday 10 December 2014

SearchVirtualStorage: DataCore boosts performance, adds Storage Accelerator and QoS to SANsymphony-V10 and Virtual SAN

DataCore Software's SANsymphony-V10 now features a random write accelerator to improve performance of write-intensive workloads.
DataCore Software Corp. updated its SANsymphony-V10 storage virtualization software to boost performance and scalability, add quality of service capabilities and provide tighter integration with Microsoft Azure cloud services.
...The DataCore software runs on standard x86 servers and manages the capacity of their internal disk and/or solid-state drives (SSDs) as a shared storage pool.
One of the key features in the SANsymphony-V10 PSP1 update is the random write accelerator. DataCore said the new technology converts random writes into sequential writes to improve the performance of write-intensive workloads such as databases, ERP and online transaction processing systems, and workloads that use RAID 5 data protection.
Jon Toigo, CEO and managing principal at Toigo Partners International LLC, said DataCore could also position the random write accelerator to address the performance-degrading I/O blender phenomenon. The I/O blender effect occurs when multiple virtual machines try to write data at the same time.
"It's basically doing some log-file structuring and some write coalescence that turns a whole bunch of random writes into sequential writes so that you speed up the performance of your storage," said Toigo, who is a user of DataCore software.
Updates boost performance, management
Augie Gonzalez, director of product marketing at DataCore, said Iometer testing of 100% random write workloads with a 4K block size showed 33 times faster performance, with low-cost SATA hard disk drives (HDDs) running on Dell servers. According to Gonzalez, using identical test conditions, the random-write-accelerated SATA HDDs outperformed multi-level cell (MLC) SSDs that did not use the new "turbo charger" feature.
Gonzalez said, when using the random write accelerator, the SSDs also saw performance 3.6 times faster than without the write accelerator. The acceleration technology, coupled with the product's caching mechanism, also helps to reduce the write-induced wear-out factor of SSDs, he said.
SANsymphony-V10 PSP1 increases the maximum number of server nodes supported in hyper-converged configurations from 32 to 64. That allows customers to spread workloads across more servers in a cluster to boost throughput. The company said each server can support more than 1 million IOPS, and the extra scalability can be especially helpful with distributed latency-sensitive applications and large virtual desktop infrastructure (VDI) deployments.
"Let's say the production cluster is running out of space," Gonzalez said. "Before this customer can stand up another server and put more storage on it, they've got to get over this afternoon's processing window. Their test and dev cluster has extra space. Normally those two couldn't touch each other. In the case of DataCore, having a common storage pool, we can basically loan that production cluster some temporary capacity."
SANsymphony-V10 PSP1 also introduces quality of service (QoS) controls to enable customers to manage and regulate the system to ensure that low-priority workloads don't monopolize resources that more critical applications need. The new release features host group access control to let administrators assign different application hosts to different segments of the storage pool.
"The combination allows you to segregate local partitions of the data to where you need it but also to remap it when you need to," DataCore CEOGeorge Teixeira said.
Gonzalez noted that DataCore's QoS applies not only to capacity but also to Fibre Channel and iSCSI connections with the host. With PSP1, the company has added utilization tracking capabilities and chargeback reports to enable customers to manage their storage infrastructure as a private cloud.
Another new option in SANsymphony-V10 is the ability to have a standby node to enable full performance during software updates, equipment refreshes and maintenance tasks or to offload responsibilities from an overtaxed node. The product already supported automatic failover between nodes in the event of a storage or device failure, but there was a performance impact. DataCore customers will now have the option to shift workloads to a standby node without disrupting the applications or degrading performance and throughput.
Teixeira said the standby node will be especially helpful for customers such as banks or hospitals that use metro clusters or metro mirroring stretching across different locations. While this type of feature traditionally appeals to customers with no tolerance for failure, and who are willing to pay for an extra server to get an even higher level of availability, falling server prices could bring it to more midmarket IT organizations.
DataCore looks to public cloud for backup and DR
With the PSP1 update, DataCore also gives customers additional options to send data to public cloud storage for off-site backups, archives and disaster recovery. The company tightly integrated and certified its SANsymphony-V10 to work with on-premises Microsoft StorSimple hybrid cloud arrays, which can serve as a bridge to Microsoft's Azure public cloud storage.
"One of the advantages we bring to Microsoft is that their array only works with iSCSI storage," Teixeira said. "We work with both Fibre Channel and iSCSI, so we can virtualize all the storage on-premises, whether it is Fibre Channel or iSCSI based, and we can automatically tier and migrate it to the StorSimple gateway."
...Teixeira said he is especially focused on Windows Azure because the service caters to business use involving databases such as Microsoft SQL Server and Exchange Server.
"When we talk to our customers, what they're looking for is a rock-solid commercial capability out there, and Windows Azure seems to be that platform for most of them," Teixeira said. "So, getting it jointly certified was key for us. I think it's probably where we're going to see the most pickup from our customer base."

A2 Dominion Housing Group - Performance Improvements of Critical Apps with DataCore Software-defined Storage

UK Software-Defined Storage Customer Endorsements Span Any Hypervisor, Any Storage, Any Location 

DataCore, a leader in software-defined storage and Datashare Solutions,(Shift F7 Group) a DataCore go-to partner, are highlighting the momentum in the UK towards adoption of software defined-storage (SDS) solutions. Datashare Solutions has compiled a testimonial briefing pack outlining key buying criteria and customer adoption reasons.  

Shift F7 Group Marketing Manager, Sue Beckwith, explains more, “It’s been refreshing to compile this testimonial document as it really brings the ‘software defined’ experience to life. SDS has been much hyped of late, but as you can see from our customer endorsements, we have been successfully implementing DataCore’s software abstraction layer across any storage and on any hypervisor for many years now. It truly and flexibly stands the test of time.”
Company: A2 Dominion Housing Group - Performance Improvements of Critical Apps:
When one of the UK’s leading Housing Associations’, A2Dominion Housing Group, had a requirement to increase the performance of their core housing application and improve the recovery capabilities for the application in the event of a disaster, they engaged with Datashare Solutions for a solution. Their existing SAN was not able to deal with the high I/Os from replication and suffered a significant number of cache misses with an adverse effect on the performance of their critical applications for the users.
The existing hardware based SAN seemingly offered enough spindles for adequate disk performance, good capacity and RAID resiliency but was unable to cope with the load placed on it by the users. Installing DataCore SANsymphony software based storage, enabled the organisation to significantly increase their cache hits; increase server RAM and add a layer of high performance SSD. The solution also enabled near synchronous replication between A2Dominion’s primary and backup data centres, significantly reducing their RTO.
“There has been a marked improvement in application performance since the implementation – we were very impressed with the fact that we could improve performance and our recovery objectives with DataCore” Mark Prosser, Head of Service Delivery, A2 Dominion Housing Group

Datacentre Solutions: One of the world’s largest online gaming companies NetEnt turns to DataCore’s software defined storage

NetEnt realises the business value of DataCore’s Software-Defined Storage

One of the world’s largest online gaming companies turns to DataCore’s software defined storage, SANsymphony-V.
Europe’s largest gaming company, NetEnt uses DataCore’s SANsymphony-V software-defined storage platform to safeguard it’s customer data and add the needed flexibility and cost efficiencies to deal with high data growth rates of over 30% quarter on quarter. NetEnt operates in one of Europe’s most dynamic, intensely regulated and competitive business sectors. Today, DataCore enables NetEnt’s business to meet its business continuance objectives; to prevent storage from disrupting critical applications and to work across heterogeneous systems and diverse legal requirements. This enablement allows NetEnt to perform its business and support over 16 billion transactions a year.
NetEnt Live Roulette
As a premium supplier of online casino games, NetEnt services’ are used by many of the world’s most successful online casino operators. NetEnt operates its business from several data centres across the globe, including the company’s primary data centre in Malta. Supporting a vast degree of varying sized customers, with different cross-border compliance regulations, NetEnt’s Infrastructure Architect, Anders Redaner faces a 24x7x365 global challenge to ensure zero downtime in a highly performant infrastructure:

Business Continuity: Software-defined Storage Eliminates Single Points of Failure
“100% safety of customer data and high availability 24/7 of hosted services has always been our top priority. In our previous hardware based environment, we had identified potential single points of failure using our existing high capacity storage arrays operating as isolated islands which we needed to address and federate.”
It was the support and management of different models of hardware used for different customer scenarios that caused NetEnt to spend too much time on migrating customer systems between arrays. Firmware upgrades could not be guaranteed with 100% data security and availability, also performance and capacity issues proved to be inflexible, hard to solve and costly to fix.

DataCore SANsymphony-V: A Comprehensive Solution
A fundamental overhaul of the storage architecture was needed to provide 100% customer data security and high availability with no risk of data loss; increased flexibility for storage performance and capacity management, today and in the future, and better cost efficiency. NetEnt evaluated several storage solutions proposed by vendors like HP, IBM, HDS, NetApp, EMC and others. But what they could not pin-point was a vendor who could bring one comprehensive solution that offered both future scalability and the flexibility to accommodate the diverse needs and differing sizes of different Casino platforms.

NetEnt was initially introduced to DataCore at an industry event where it learned about its pure Software-defined Storage approach. A detailed proof of concept process was soon started to test the stability, performance and functionality of SANsymphony-V. Anders details the journey to DataCore within NetEnt:

“Amongst all well-known storage vendors, there was no real encompassing solution until we evaluated DataCore’s SANsymphony-V software. DataCore’s Software-defined Storage platform gives NetEnt all the storage flexibility, high availability, performance and functionality required and improves our overall data security with an adaptable design for future requirements, which is a key priority for us”

Simple and Non-disruptive Migrations with SANsymphony-V
Procurement of new hardware also occurred. Hitachi Data Systems (HDS) were bought to replace legacy HP storage, but the purchase came with a welcome increase in performance and a lowering of the cost of storage hardware. This was possible since the fully agnostic SANsymphony-V software layer enabled the systems to be migrated without disruption and added performance acceleration to the entire storage infrastructure.
Anders comments: “With DataCore, we are free of a hardware vendor lock-in and migration from one platform to the next is easy.”

Worldwide today, 14 SANsymphony-V nodes have been deployed running on HP Proliant servers, each equipped with 256 GB RAM and DataCore’s high speed caching. DataCore now virtualises, pools and optimises the HDS storage hardware and centrally manages all storage from the DataCore Software-defined storage platform. Over 400 TB and 1500 virtual machines are now supported by the DataCore infrastructure. The SANsymphony-V architecture provides high availability and performance for the CasinoModule™ production systems backed with underlying Microsoft SQL data bases and systems under Windows, Linux and VMware. For total resilience, SANsymphony-V is used to synchronous mirror production data and safeguard it between data centres worldwide and within separate fire proof sections inside individual data centres, safely securing the core business of over 16 billion transactions, each year.

“The combination of DataCore SANsymphonyV with dual HDS Arrays gives NetEnt a very secure and highly available solution that can handle the company’s current and future requirements through its flexible topology. We have achieved full redundancy independent from storage systems and gained the flexibility to scale, migrate or change the hardware exactly to our needs.” reflects Anders Redander.

Software Flexibility to Meet Future business Needs and Changing Legal Regulations
NetEnt summarized their strategic targets and how they were achieved through DataCore’s SANsymphony-V Software-Defined Storage approach by volunteering to present their SDS experience independently to European audiences at this year’s IP Expo Europe (London, 8/9 Oct 2014). <>. Anders concluded that his customer data is safe and sound. Storage failures no longer impact critical applications and 100% high availability is now achieved by removing all single points of logical and physical failures. Now fully enabled with a more flexible storage infrastructure solution, NetEnt has significantly reduced its workload and management overheads, enabled non-disruptive updates, changes and migrations by utilising an adaptable design that improves productivity and accommodates changes brought on by future regulations. Costs have been regulated and whether servicing large data centres or smaller installations, the benefits are equally reaped by both.

The Register: DataCore lifts baton, strikes up the 64th SANsymphony with latest update release for SANsymphony-V and Virtual SAN

Comment DataCore has updated its SANsymphony and Virtual SAN software products to reach 100 million IOPS and 64PB capacity. It's also getting into bed with Azure.

SANsymphony-V10 PSP1 builds a SAN from a cluster of servers, aggregating each server's storage into a central virtual pool. The company has built its product on virtual SAN technology which VMware has now blessed as a concept with its VSAN technology...
...DataCore says that - unlike VMware's ESXi-only VSAN - its Virtual SAN supports any hypervisor and any storage.

Its software enhancements mean the following things:
  • Systems can scale out to 64 nodes, up from 32
  • They can scale up to 64PB configurations
  • Notionally they can deliver more than 100 million IOPS
Claiming a 64PB and 100 million IOPS capability is bold; achieving it will be impressive.
The SANsymphony V10 PSP1 product has quality of service (QoS) features providing policies which manage access to storage tiers divided between on-premise and public clouds, defining storage resource allocation and providing Service Level Agreement capability. This ensures high priority applications aren't slowed by less important ones whose consumption of resources is controlled by capping their data transfer rate and IOPS.

DataCore says storage resources can be logically segregated, monitored and regulated on a departmental basis. This SW release also adds utilisation tracking capabilities and chargeback reports.
Random Write Accelerator technology has been added, which - DataCore says - benefits ERP, OLTP and database applications with up to 30 times faster writes. This secret sauce is said to provide a greater than 30x random write improvement on RAID-5 protected datasets with data and metadata - reconstruction information - spread across multiple locations on different disk drives.

It is also said to be especially effective with slower SATA disk drives exhibiting longer rotational and seek delays when updating data blocks. And flash can benefit too, with SSDs having lower write amplification and less wear, as well as a claimed 3.6x increase in IOPS.

This sound to us like some kind of random write buffering transforming many random writes into fewer sequential ones.
Doubling the node count in Virtual SANs helps increase the number of applications they support or the number of users in the VDI use case. DataCore says resources can be shared across multiple clusters as well.
There is zero-touch failover to provide non-disruptive failover if either a storage or server component fails. Internet mirrors can span 60-mile (100 kilometre) distances.

Microsoft Azure integration

SANsymphony-V can use Microsoft's Azure cloud core via a Microsoft StorSimple array with a very, very long name - the DataCore-ready certified Azure StorSimple Hybrid Cloud Storage Array.
In a hybrid cloud scheme Azure provides backend geo-redundant cloud storage, with SANsmphony-V auto-tiering on-premise storage to StorSimple Arrays and hence Azure. The StorSimple arrays can be pooled like any other SanSymphony storage.
Working set backups (snapshot copies) can be sent to Azure through the StorSimple gateways. They can be retrieved from separate locations by other StorSimple arrays or by Azure-hosted applications.
If accessing hosts use Fibre Channel, SANsymphony-V converts this protocol to iSCSI.

Bits and bobs

There's more; SANSymphony V10 PSP1 gets performance-monitoring capabilities, wizards to automate processes such as software updates, and enhanced CDP capabilities for restoring from known good points-in-time.
There is now a standby node capability whereby workloads can be redistributed when an existing node is taken out of service or gets overburdened in a SANsymphony-V group.
The latest Fujitsu PRIMERGY BX and CX servers are certified as DataCore Ready Software-defined Storage servers. Fujitsu's ETERNUS DX arrays have gained DataCore Ready Certification.
SANsymphony V10 PSP1 and VirtualSAN are shipping now with the enhancements above. DataCore's 10,000 customer sites should be pleased with this raft of new features as their mature product gets significantly extended.
