Qsan Technology, Inc. and Enhance Technology, Inc.’s iSCSI storage has passed Vmware Hardware Certification Program. By Qsan’s P200C iSCSI GbE (X4)-to-SAS/SATAII RAID controller and Enhance’s strong consolidation for enterprise & SMB storage solution, the Enhance Technology UltraStor RS16 IP-4 now is VMware ESX 3.5 compatible and fully certified.

RAID controller

With the largest market share in virtualization and concentration since 1998, VMware provides users for saving overall cost by its green nature for fewer servers required, reducing IT cost with high flexibility, and deceasing planned and unplanned downtime. VMware ESX 3.5 enables multiple virtual machines to share physical resource on the same server hardware, run unmodified operation systems and applications, and run the most resource-intensive applications side by side on the same server. VMware also provides variety of operation system choices for most of usages and applications. By the long time of verification and stress test, VMware VMtion can leverage the complete virtualization of servers, storage systems and networking to move an entire running virtual machine instantaneously from one server to another. And it only takes seconds. With more features not mentioned here, Vmware makes virtualization and your cost a lot of easier.

Enhance Technology UltraStor RS16 IP-4 is the latest iSCSI GbE (X4)-to-SAS/SATAII storage system which is composed of Qsan Technology P200C iSCSI RAID controller. Qsan P200C is built around with Qsan innovative RAID stack, featuring industry-leading performance on Intel IOP platform. With 4 GbE iSCSI ports connected to the host/GbE switch, either working independently, trunking/LACP, or MPIO together, the benchmark data shows up to 120,000 IOPS and the throughput can achieve up to 600MB/sec.

The outstanding performance is produced by not only the highly-optimized Qsan storage stack but also strong computing power offered by Intel Xscale IOP342. At drive-side, P200C supports SAS drives, thus SATA compatible. Not only it supports up to 16 drives in single enclosure, there is a SAS JBOD expansion port built-in, connectible up to 4 SAS JBODs (Enhance Technology UltraStor RS16 JS) and up to 80 drives installed. The SAS interface adds flexibilities, higher performance, and very cost effective expansion.  And with the green feature of disk auto spindown supported by Qsan, the whole system including one P200C and four SAS JBOD enclosures with fully loaded 80 hard drives can achieve high power efficiency and save the overall drive power cost. Other useful features are also included, such as RAID 6, on-line migration, web-based management, snapshot (QSnap) and so on.
