At present, X-IO Hyper ISE 7-series arrays contain two X-IO DataPacs totaling 40 drives, of which 10 are 200GB eMLC SSDs providing 1.6TB of flash. The 740 will double the capacity of flash drives to 400GB for a total of 3.2TB, made up of SMART Optimus 2.5” eMLC flash.
As with other 7-series arrays 2.5” SAS HDD capacities will be 300GB, 600GB or 900GB for a total array capacity of 21.6TB before RAID formatting, with eight 8 Gbps Fibre Channel ports.
The Hyper ISE 740 – that will ship in early 2013 – will not deliver a higher overall input/output per second (IOPS) figure than other 7-series devices (a quoted maximum of 300,000IOPS) but will allow more operations to benefit from higher I/O performance by shifting I/O to flash with its automated storage tiering software, CADP (Continuous Adaptive Data Placement).
It is aimed at virtual desktop infrastructure (VDI), OLTP and business intelligence (BI) use cases.
X-IO solutions development director, Gavin McLaughlin said: “We are boosting SSD to HHD capacity ratios from 8% to 15% to cater for such instances as in VDI where large boot storms hit and the array needs to deal with a lot of reads at once. CADP sees hot spots on the SAS drives and balances that data over to flash to deal with those reads.”
X-IO sells storage arrays with its proprietary sealed drive DataPacs, which are in part a legacy of IP acquired when it bought Seagate’s Advanced Storage Architecture group in 2007.
A key selling point is that its DataPacs bring reliability and utilisation beyond that possible from other storage suppliers that use commodity drives, by incorporating low vibration, self-healing and granular failure repair characteristics, such as the ability to lock off a single platter surface rather than fail a whole drive.
