Newbie wants to put high speed disks within V440 server
Good afternoon,
I have a Sun Fire V440 server, in which there are 4 Fujitsu "MAY2073RCSUN72G" disks and 8 Seagate "ST373207LSUN72G" disks.
I would like to boost the performance of that server by replacing the mentioned disks, which turn at 10,000 Tours/Minute, by other disks which turn at 15,000 Tours/Minute or even more.
Following the V440 datasheet, the only kind of internal disks that can be used are "Ultra320 SCSI" disks.
Does anybody know whether there are disks of higher speed that I could use within my server?
Thank you
Dominique

How do you fit twelve disk drives into a chassis that can only hold four ?

Perhaps you have some externally attached array(s), as well ?
You might be mis-interpreting the specifications that you have been reading.
No matter what disk drives you use, the data transfer rate will be limited
by the SCSI chipset in the platform, which is a 320MB/sec burst in the V440.
Disks with a faster rotational speed could possibly find a data sector
faster, but would you actually see any improvement in throughput ?
I predict that in real world circumstances, you will not.
Save your money.Spend it on fibre-attached external storage.
Get GB/sec burst throughput with that other technology.

Here is an online treatise from the Ars Technica Paedia, entitled "What Is SCSI?"
