Friday, April 3rd, 2009United Digital PCIe RAID first Look
Thursday, March 26th, 2009So last week we took delivery of our first United Digital 9116 PCIe RAID.
Unlike traditional RAIDs that connect via either a SCSI or Fibre card the United Digital 91xx series connect directly to the PCIe bus of the host Mac. This pretty much eliminates bottlenecks caused by traditional connectivity methods.
I like the design of this raid. it has a very simple easy to use web management console, easy to set-up email notifications for if things go wrong.
The system I was testing was a 9116 a 16 bay subsystem comprising of 8 x 750Gb SATA Hard Disks. This was connected to a 2.8GHz Quad Core Mac Pro running Mac OS 10.5.6 & 6Gb RAM.
Using Xbench the results were astounding: I was getting a sustained read speed of 669 MB/sec & sustained write speed of 470 MB/sec. I compared this against an Xserve RAID (7 x 250Gb HDD @ RAID 5) which could only muster read/ write speeds of around 140Mb/sec.
With performance figures like these, couple this with 10Gb Ethernet we could potentially have a serious lower cost rival to Xsan systems.
