What is Oktawave Volume Storage (OVS)?
Posted by Maciej KarmaƄski on 28.12.2012 15:39

Oktawave Volume Storage (OVS) is a logical unit running in the virtualized resources of Oktawave data center, defined by the amount of disk space (expressed in GB, gigabytes) and available in internal storage network in a form similar to the hard disk (as a block device recognized by the operating system as a disk).

OVS is a block storage sharing system (same as the matrix or the disk), but its operation speed is comparable to the matrix with several thousand conventional (magnetic) disks SAS. Real access time for OVS Tier-2, Tier-3, Tier-4 and Tier-5 is measured in microseconds (while the matrixes, or standard disks operate in milliseconds).

OVS is the network based on FC SAN 16Gbps, providing bandwidth of about 1.8 GB/s for each instance, and up to 200,000 IOPS (for Tier-5 disks) and about 150 MB/s and 1000 IOPS for Tier-1.

OVS important feature is the ability to smooth and uninterrupted migration of shared resources between all three Tier's, online, and matching performance to your needs. In laboratory tests, Tier-5 reached 1 million IOPS performance for OCI with 64 GB RAM and 16 VCPU, and the currently available 200,000 is a software-limit, which over time will be increased. Main feature of OVS is a data replication between storage nodes, which guarantees continuous availability regardless of the failure of any component.

OVS is the logical equivalent of ultra-fast hard drive and is ideally to run databases of all sizes and any load. Operating speed of this database (for Tier-5) can be compared with a data processing on ramdrive.
