>> 10 drive raid >Which controller? Chipset? Battery backup? RAM?
Looking at an adaptec U320, 256 MB w/battery backup for 72 hours. The rest of the system is a SuperMicro serverworks dual xeon mobo + case. It has 10 drive bays in the 4U case with a backplane and hotswap. 4GB of ram. About $6,000 for the whole thing. >> What RAID config would you use for the databases? >Depends on what RAID controller you have. If it is IOP321 based, 10 disks in a RAID 6 or 9 disks in a RAID 5 and a hotspare. I didn't know what RAID 6 is -- "RAID-6. This type is similar to RAID-5 but includes a second parity scheme that is distributed across different drives and thus offers extremely high fault- and drive-failure tolerance. There are few or no commercial examples currently." So you would have only one data volume for the two databases? What about the logs? >> How important is (battery backed) write cache for the raid? >It is the single most important way to improve performance on the hardware side. Sounds like this would be a hard limit on scalability for connections per second because of the cfsessions client vars.
