Q

From iSCSI to Fibre Channel storage -- when to switch

Assessing Fibre Channel (FC) versus iSCSI benefits depends on storage capacity. Read expert Brain Peterson's advice on deciding when a switch is necessary.

When should a VAR recommend that a client invest in Fibre Channel instead of using iSCSI?
It is commonly understood that iSCSI SANs makes sense in SMB environments with fairly simple external storage needs, or where an existing Fibre Channel (FC) SAN does not already exist. A Fibre Channel (FC) SAN becomes necessary when nothing else will do the job: For example, if the customer's capacity or performance needs to dictate a storage array that provides more bandwidth via FC than via iSCSI.
