Netserve E800 / NetRaid 1Si Drive Compatibility

[Ron Allen_1]

Hi, I have an E800 with Netraid 1SI card and (2) 9 gb Ultra2 SCSI drives. Need to upgrade drives but not sure what is compatible since Ultra2 drives are to buy. Will Ultra3 10,000 RPM drives work with my Netraid card? Thanks in advance!

hi,
netraid 1SI do not mind about the kind of disk (U2/U3 or 7K/10K), so you can connect them, but if you have to add these disk to an existing logical raid, you should use same RPM disks, and/or compatible disks.

This is true. All SCSI are compatible Ultra, Ultra2, Ultra3, Ultra160, Ultra320. It is said that mixing rotational speeds is not "supported" but we have had not customer problems doing this and can not come up with a reason why it would make a difference. You are only changing the access time a few miliseconds, the controller is still going to be using Ultra2. But for you it sounds like you just want new drives, just remember you will have to create a new array, so backup and restore is required.

It is recommended that drives within the same RAID array be the same if possible.
