Hello,

I have a HP 4204vi switch.  I'm looking to use a SAN of off it on a VLAN.  However, the switch does not support jumbo frames.  Will I see major performance issues if I don't have that feature?

It's generally recommended by your SAN vendor, to enable jumbo frames, but performance can vary, between network equipment and SAN.

You are only likely to notice, when you are stating to push the connection, using iSCSI

9K bytes in Jumbo frames are 6 times higher then standard 1500 MTU. Less frames on network means less overhead and better performance  .

Performance difference is less than 1% with or without jumbo. Not really worth the effort. But troubleshooting every now and then tech support asks for it. God knows why.
