Hello everyone. I am about to add another RAID 1+0 array to my SQL 2000 database. It will be (14) HP Ultra320 Drives, 72 Gig, 15k RPM. It will have the top-of-the-line SA 6404 Controller, with 512 Megs of Battery-Backed Read/Write Cache. It will all be in an MSA3000 Dual-Bus RAID Cage. I will be getting full U320 speed, and that is what this upgrade is all about: SPEED. I am moving one of our main databases from a shared RAID 1+0 array to its own on this new system, and giving it its own dedicated Log array as well.<br />
<br />
So now that you have the &quot;environment&quot;, the question: What is the optimal Cluster Allocation and RAID Stripe sizes for pure speed in SQL? We have PLENTY (and I do mean plenty) of physical space on the drives, so I am not concerned at all about wasting space due to larger clusters. Most things I have read have said 64K for both the clusters and the stripe, but I have also read a few things recently that recommend 64k for the cluster and 128k for the stripe.<br />
<br />
Anyone have any thoughts? I am implementing this tomorrow (Saturday July 1st), so any input is greatly appreciated.<br />
<br />
Thanks,<br />
Troy

Optimal Cluster Allocation/RAID Stripe Size on SQL 2000

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
