RAID setup in SAN

[Prasanna Venkatesh]

For the Blade servers, Can I set up a RAID in a SAN solution without the useage of RAID controllers?

[Ivan Ferreira]

Yes you can. You need an HBA (Host bus adapter) in the server in order to connect to the SAN Storage.

I see! This would mean that The RAID setup would be entirely in the SAN common to all blades and I would need a HBA to connect the server to the SAN, right?

Would I need a HBA for every Blade in the enclosure?

Yes.

I think that the blade servers can share one HBA connected to the blade enclosure, consider the performance issues of this.
