SAN and RAID

Hi Guys,
I have question regarding RAID and SAN. For disk arry, does SAN use RAID in
the disk array? what is relationship between them? Thank.A SAN uses RAID technology as part of a storage solution. Unlike
direct-attached storage, a SAN provides storage virtualization and features
to improve availability, manageability, scalability, fault tolerance and
performance.

Hope this helps.

which RAID a SAN can use? Thanks.

The RAID level and configurability depends on the features of the specific
SAN. A SAN is proprietary solution but the ones I've worked with support
RAID 5 and 10.

To be clear, you can use both in the same SAN.
I think Network Appliances even uses RAID 4.

Email: sql (at) greenms.com http://www.greenms.com/sqlserver.html|||Iter, it sounds to me like you are considering (or have already) purchasing
a SAN for use with SQL Server. You REALLY REALLY should get professional
help in setting this up correctly since you appear to be a newbie with them.
Configuring this yourself will lead to VERY suboptimal performance,
guaranteed. You simply cannot learn what you need to do this from a few (or
even many) forum posts.
Note that (in my esperience) most SAN-vendor-employed-consultants know VERY
little about how to properly configure a SAN for SQL Server usage.
