DataCore is a provider of storage control and storage management software.
SANmelody disk servers are a compelling alternative to conventional storage arrays and iSCSI appliances, they are lower in cost, simpler to set up and yet they can be easily expanded to include all the powerful productivity features previously available only on high-end Arrays or SANs. The software is the industries most affordable and powerful approach to serving disk storage to LAN or FC attached application servers. SANmelody is targeted at small business, workgroups and enterprise departments.
The SANsymphony storage platform is targeted at the enterprise-class data center market and traditional SAN environments with more complex storage deployments. SANsymphony has a proven track record, having been sold and installed at hundreds of blue-chip customer sites worldwide, and the product has been recognized for providing leading edge storage virtualization to large enterprises with complex heterogeneous and tiered-storage environments like Lufthansa and AmeriGroup. With SANsymphony, enterprises are able to improve the overall performance and availability of their hardware investments, and reduce total cost of ownership through optimization and simplified management.

As regards quality of service, having DataCore software in front of intelligent shared arrays as well as mid-range and low-end disks actually accelerates their performance. This is a result of a powerful cache multiplier effect, unique to SANsymphony. The additional performance and enhanced channel fan out can be used to share the vital storage resource with more servers. Diverse paths through the networks and N+1 redundant nodes ensure no single point of failure.

16. SANsymphony Product Introduction
Auto-Provisioning
12TB allocated
No Agents on Hosts
2TB volume (NVM) assigned to each server
Small fraction of real capacity allocated to each virtual disk
SANmelody automatically allocates capacity when needed
SANmelody Category D adds even more capacity, performance capabilities, high availability and data protection features. The ability to automatically provision storage capacity is a unique feature of SANmelody that will save time, simplify administration and reduce wasted capacity. Finally, we get rid of the guessing. Instead, SANmelody elegantly auto-provisions just enough space, just-in-time to needy servers. It does so in real time by assigning very large “virtual disk images” to each server. By large, we mean the largest addressable disk an operating system can handle (often 2 terabytes).
In much the same way that virtual memory operates, all of the servers think they have plenty of room. Physically, however, only a fraction of real space is assigned to the pool. The amount on day one is dictated by current actual requirements plus a reserve for near term growth.
Those applications that consume additional capacity as time goes on, deplete the free space, many never reaching anywhere close to their 2 terabyte virtual allotment. SANmelody doles out additional real space in granular increments, say 128 MB and monitors for use before granting more.
Over time, as the free space for the entire pool is chewed up, the low reserve mark is reached, triggering a notification. 20% reserve is common. Upon this alert, additional disks are acquired and added non-intrusive to the pool, upping the free space to a comfortable level once again.
The servers, and more importantly their users and applications are never interrupted.

18. SANsymphony Product Introduction
Snap Shot
Snapshots
Instantaneous Point-in-time snapshots
Complete Images
Snap from FC to SATA disks
Production Volume
Snapshot Copy
Disk Snapshots Take Place of Daily Backups Disk Servers can be configured to periodically generate daily 'snapshots,' or point-in- time copies, of critical volumes on separate disks -- eliminating the need for daily tape backups. The snapshots may be mounted just like a removable drive to rapidly restore an application to a known good image from the previous day. Where conventional tape backups can disrupt application processing for several hours, an online snapshot only requires a brief application pause to record the current state of the data. Immediately after a snapshot is taken, the 'live' source volume is released and applications may resume updates. SANmelody then captures subsequent changes to the data in real-time on a separate volume. This process dramatically reduces the time to create a "backup copy."
Use Auto-Provisioning with Snapshots to conserve capacity

Snapshot View
Point-in-time Snapshot (Backups, testing, etc.)
Live Volume
The magic behind snapshots is in making the backup server believe it is sourcing all the information from a frozen-in-time image.
The backup image is really a snapshot “view” concocted by combining unchanged blocks on the live volume with copy-on-write blocks on a separate virtual disk. SANsymphony’s copy-on-write operation preserves the original contents of the live volume prior to updates to maintain the illusion.

22. Why go Virtual? What is the driving force to go Virtual?
Flexibility to Adapt to Change + Economics and Productivity:
Saving Money, Time and Effort
Better utilization and consolidation of assets
Rapid response to address growth and change
Hardware Independence and Cost Savings
Productivity gains by consolidating tasks, process and resources
Server Virtualization
Processor utilization, for example, Intel/AMD typically CPUs averages utilization of less than 10 percent - 90% waste
Storage Virtualization
On average 25% of allocated physical disk space in Microsoft environments is effectively utilized by users – 75% waste

23. SANmelody: Target Customers
Customers who:
Are seeking entry-level SAN capability ($10k-$50k storage budget)
Have a limited infrastructure seeking low cost disk solutions
are implementing virtual server infrastructures
Have a low-cost DR or business continuance requirement
Have application servers, 500GB – 5TB+
iSCSi or Fibre Channel storage connectivity

Example
Building Building Remote Site
This financial company purchased 2 TagmaStor boxes for production. Instead of purchasing a third Tagma to replicate to they moved one of the production boxes to the DR site, added some EVA storage for production and used SANsymphony to replicate. The result was huge saveings and cost avoidance.
