IBM has launched an upgrade option for its grid based XIV Storage System, which allows for the utilisation of solid-state drives (SSDs) as cache. This will in turn increase the set-ups performance, by almost three times.
Last July, IBM launched the XIV storage system's third generation that raised the capability from 256GB to 360GB of DRAM, besides shifting from serial ATA (SATA) drives to SCSI (SAS) drives - for a better overall performance.
This latest upgrade, with the SSD caching option, allows users to store data on flash memory, located between the hard drives and DRAM. The company confirmed that they have used 400GB SSD drives, for increasing the capacity, up to 6 TB.
An IBM's spokesperson stated in an email that "Unlike some of today's storage systems that incorporate multiple drive tiers (i.e., SSD, enterprise hard drives, and near-line drives), the XIV system is unique in that it uses only large, nearline drives for enterprise workloads." reported Computer World.
NetApp and EMC, plus other main competitors of IBM are already offering SSD options, within their arrays.
The company also introduced an Apple iPhone application that allows the administrators to monitor the XIV storage environment, via web browser interface.
