Review: Hewlett-Packard's Next-Gen Z620 Workstation

HP has boosted the Z620's storage-controller options, adding an 8-port LSI 9717-4i4e SAS controller and LSI 9212-4i 4-port SAS RAID card. That's on top of the motherboard's Marvell SATA controller with six channels for RAID 0, 1, 5 and 10, two of which can handle 6.0 Gb/s. For system and booting, the company this year uses Seagate Pro series SSDs (instead of Micron).

The test system also sported a pair of Hitachi 7200K 6.0 Gbps spinning drives in a RAID 5 array controlled by an LSI MegaRAID 9260-8i. Against this array, the Z620 turned in a sustained data transfer rate for sequential reads of almost 370 MB/s. That's on par with some of CRN's Top 10 Servers.

Transaction and throughput performance were measured with IOmeter. For this test, peak performance was found with sequential 4K reads and a queue size of 48.
