SANsymphony-V software solves difficult storage-related challenges introduced by server and desktop virtualization, cloud computing and more general expansion, business continuity, and disaster recovery initiatives. It forms an active, transparent virtualization layer across disk storage devices to maximize the availability, performance and utilization of datacenters large and small.
SANsymphony-Vforms a transparent, scalable virtualization layer across your storage infrastructure in order to enhance its capabilities and centralize its management. The many nuances and incompatibilities distinguishing different models and brands of storage no longer stand in the way of using them together.
Provisioning disk space
TheSANsymphony-V administrator carves out virtual disks on demand from the physical disk pool according to the capacity, availability and performance needs of each workload.
Replicate offsite for disaster recovery and migration
For additional offsite disaster recovery, or simply to migrate data between locations, SANsymphony-V replicates disks asynchronously over unlimited distances using conventional IP lines. You can also reverse the direction of replication to restore the original site after the danger has been averted. For additional confidence, remote restoration procedures may be tested regularly while normal production processing goes on at the primary data center.
Cache overcomes I/O bottlenecks
DataCore taps each node's processing, memory and I/O resources to carry out advanced functions across all of the storage devices under its command. SANsymphony-V reserves up to 1Terabyte of random access memory per node for SAN-wide "mega caches". Thanks to the sophisticated multi-threaded caching algorithms, data written to or read from disks move swiftly into and out of the caches, harnessing the full potential of each node's high speed multi-processors. Caching makes application run faster than they would had if they accessed the disks directly, whether connected to top-of-the-line storage systems or lower end gear.
Automatically optimize disk access across tiers
Disks with different price/performance attributes can be organized into separate storage tiers. For example, the fastest tier may be composed of Solid State Disks, with lower tiers made up of SAS and SATA drives, respectively. The same tier may include similar units from different manufacturers acquired overtime. SANsymphony-V automatically promotes frequently accessed disk blocks to faster tiers and demotes less active blocks to slower, more cost-effective drives based on the IT team's criteria. You may override auto-tiering policies by explicitly defining which disks should be used for special workloads or confine the selection of tiers to a narrower set of resources.
