DataCore SANsymphony-V 8.1 to go GA this week

DataCore is about ready to release its latest version of SANsymphony-V (SSY-V), version 8.1. The hallmark of this release is centered around a new feature in the DataCore toolbox called auto-tiering. Auto-tiering is similar to other technologies such as EMC’s FAST Cache (Fully Automated Storage Tiering) feature. The major differences are, as with everything DataCore, it is vendor neutral and extremely flexible.

Auto-tiering merges high capacity with high performance. In the storage industry we are seeing extremely large drive capacities (3-4TB per drive) being made available from various vendors. No one would argue about the need for this type of capacity, but performance has remained fairly constant over the years. By leveraging auto-tiering (which promotes more frequently accessed data from slower spinning disk to ultra high-speed solid state disk), you get the best of both worlds. Auto-tiering benefits the storage platform globally, without needing to dedicate expensive solid state disk to its own storage tier.

Clearly this new feature raises the bar on delivering higher overall system performance while keeping costs low. For more details about auto-tiering and DataCore Software, see the full press release below.

DataCore Software Adds Device-Independent Auto-Tiering to Its Storage Virtualization Software

SANsymphony™-V dynamically relocates workloads across different classes of storage equipment including SSDs to achieve best performance and utilization based on IT priorities and usage patterns.

FORT LAUDERDALE, Fla. – July 27, 2011 – DataCore Software, the premier supplier of storage virtualization software, today announced a state of the art advance in automated tiering of disks. The new option for its comprehensive SANsymphony-V product automatically relocates disk blocks among pools of different storage devices, keeping the most demanding workloads operating at peak speeds. Less critical and infrequently accessed disk blocks naturally gravitate towards lower cost disks.

New Infrastructure-Wide Advance Opens up Customer ‘Purchasing Power’ for Greater Cost Savings
Unlike hardware-embedded schemes that confine tiers to premium-priced trays within a single storage enclosure or frame, DataCore’s infrastructure-wide software spans multiple storage systems from potentially different suppliers. This expanded choice gives customers the opportunity to shop for the best value at each tier from competing sources without having to discard what they purchased last year.

“SANsymphony-V customers can immediately take advantage of auto-tiering using whatever equipment they have on the floor,” notes Augie Gonzalez, director of product marketing at DataCore. “We apply the same device-independent approach to auto-tiering as we do with all our high-value services, including thin provisioning, caching, synchronous mirroring, asynchronous replication, snapshots and CDP. Let’s just say it arms you with a lot more bargaining muscle when the next disk hardware purchase comes around.”

For example, tiers may consist of high-capacity, low-priced Serial Advanced Technology Attachment (SATA) drives from one vendor, a set of Serial Attached SCSI (SAS) midrange disk systems from another, and a new collection of high-speed Solid State Disk (SSD) cards from yet a third vendor. DataCore manages these independent racks as a diverse virtual pool under a common administrative interface. Of course, the software works just as well if all tiers happen to carry the same brand.

Addressing the Cost Optimization Challenge through Automation and Transparency
The drivers, challenges and trends impacting tiered storage management are well known:

Data Growth: The amount of data in most organizations is doubling every 12 to 24 months.
Cost Deltas: Performance and high-availability oriented storage devices and SSDs typically cost 3 to 10 times more than lower tier capacity oriented storage.
Access Frequency: Over 50 percent of stored data becomes inactive within 60 days of creation.
Hidden Costs: The effort to constantly classify tiers by access frequency rates and manually move data between tiers can quickly add up to costs that eliminate any potential savings.

DataCore customers have reported up to 60 percent cost savings with SANsymphony-V alone, and now with the ability to automate and dynamically optimize tiered storage capacity, incremental savings of 20 percent or more are now possible. The final result is an extremely cost effecting, self-tuning system.

“Device independent auto-tiering is a major addition to SANsymphony-V,” said Randy Kerns, senior strategist at Evaluator Group. “Beyond the obvious cost savings, it also simplifies infrastructure-wide storage management by optimizing the promotion and demotion of disk blocks transparently in background operations. Automation eases the administration tasks and allows users to benefit from the performance gained with tiering.”

Choice of Auto-Tiering Policies
Customers govern DataCore’s auto-tiering behavior by choosing among a set of pre-defined rules. For simple, hands-off operations, the software tracks which disk blocks are most active and promotes them to the top-performing tier. The most frequently used blocks gravitate towards the faster, higher-performing devices. By auto-tiering at the disk block level, rather than at the file level, hot spots on file systems enjoy the best response compared to seldom-used areas.

System administrators can be more selective as well. They may designate from which tier a virtual disk is allocated. This option ensures that the most pressing information can be retrieved and updated faster, regardless of access frequency. Similarly, less important volumes may be relegated to lower cost, slower performing tiers, to prevent them from competing for more precious disks.

Still other virtual disks may bypass auto-tiering altogether. They can just as easily be allocated from pools with devices of similar price/performance attributes.

Infrastructure-wide caching extends high-performance tiers
The quick ascent of SSDs into mainstream IT has made auto-tiering a necessity. Specifically, it helps reserve these premium storage resources for the most demanding applications.

In addition, DataCore adaptive caching techniques boost the native performance of SSDs and conventional hard drives, while reducing the duty cycle on these more costly resources. That translates into better utilization and a longer life for these exceptional assets.

Pricing and Availability
Auto-tiering is included at no charge for SANsymphony-V node licenses supporting over 100TBs or can be added as an optional feature for the midrange of the SANsymphony-V product line, priced at $2,000 U.S.D. per DataCore node.

  1. More details on the 8.1 release:

    Automated Storage Tiering. Migrates frequently accessed data to fast storage (e.g. SSD), and infrequently data to slower (lower cost, e.g. SATA) storage within a disk pool, based on access history, within individual virtual disks.

    PowerShell cmdlet library. Provides a full-featured command line interface to SANsymphony-V. What can be done in the GUI, can now be performed thru a universal scripting interface and opens up integration with 3rd party applications such as VMware vSphere, Microsoft System Center, etc.

    Support for greater than 5 node Windows clusters. Increase the number of hosts that share virtual disks using SCSI Persistent Reserve. This means that Microsoft Windows 2008 clusters will no longer be restricted to the 5 node limitation. Microsoft currently supports up to 16 nodes in a cluster.

    VSS Enables the integration of SANsymphony-V with common Microsoft application backup environments, including Microsoft System Center Data Protection Manager (DPM).

    Offline Replication Initialization. Provides the capability to initialize virtual disks to a transportable media and then ship to the destination server at the remote location.

    iSCSI Redundant Mirror Paths. Adds support for inter-node mirror traffic over iSCSI to support mirror path failover.

    License activation enhancements. Provides the ability to activate multiple keys in a single activation, making automatic and manual activation much easier. The ability to activate partial capacity has been implemented.
