AIC BR-28 SAS Storage Cannister

Testing

The container was connected to a SAS Raid controller and container was configured as a single drive with the OS on it to give you a baseline of a single SAS drive. Then the container was then configured with a stripe (OS was spread across all drives). Next we pulled a bench mark from a single attached 10k rpm SCSI drive and a single connected SATA drive.

What is immediately noticable from the comparison above is that the SCSI hard drive has only a 5MB/s lead over the SAS drive which has a 6ms access time as compared to 10ms on the SCSI hard drive. This means the SAS drive accesses information much more quickly than the SCSI drive does and transfers almost as much infomation.

In the first image you can see that the SAS cannister continues to lead the pack with the lowest access times and the second highest transfer rate with the exceptionof the SATA Raid 0 which has a much worse access time but slightly larger transfer rate. The access time trend is continued in the second image with the same results in transfer rate. These SAS drives were obviously meant to be used in a Raid configuration which offers the strongest results.

As you can see the results speak for themselves really. If you have some money to spend to purchase not only the container with drives, but also a RAID controller along with it and of course understand what a RAID 0 is and what risk this is with running it over a RAID 5, then setting up one of these on your gaming system would be ideal.

Production Environment:

Ideal scenarios for deployment of the BR-28 include a server environment where space is a commodity and performance is a must. When integrated into our test server and deployed for use the BR-28 exhibited the faster OS and image load that we at TWL have ever witnessed. The time the BR-28 could save IT and its end clients once deployed is invaluable. Its a widely proven fact that organizations waste more money on its workers downtime (as discussed here) than on many other areas of a given organizations overhead. As we have suggested earlier spending on critical components which increase the effectiveness of your employees and infrastructure can add to your bottom line. The BR-28 addresses this concern directly by not only offering performance and reduced power consumption but by also doing so at a cost which is not extreme for an organization which would be in need of such devices.

A standard tower server may have as many as six (6) 5 1/4 bays in a tower and the same number of bays in a rack mounted 4U server. As such an organization could populate 3 of these cannisters in a server and thus offer up to 3504 Gb of high speed storage space in a single server which would be using much less power, space, and produce less heat than a comparably equipped server using standard drives.

In our tests the SAS drives performed excellent and user feedback was very positive.
