Hi

Short description of our environment..

x1 poweredge R720 with x4 nic ports for iSCSI
x2 poweregde R710 with x4 nic ports for iSCSI
x1 poweregde R610 with x2 nic ports for iSCSI

x2 EQL PS6100E
x2 EQL PS4100E
x2 EQL PS6000
x4 EQL PS5000

Everything is divided evenly between two building floors using both SyncRep and regular Replication on the EQL boxes and using one VMware HA cluster and DRS on the hosts.
Physically separated networks for iSCSI and production network.

We are using powerconnect 5448 switches on the iSCSI network. Only one PC5448 for each floor and they are connected together with x4 LACP fiber trunk link.

I know those switches should be replaced but to what? PC6248, PC7048 or Force10? Maybe even another manufacturer? If so which model? The pricetag IS a deciding factor, I don't have the budget for expensive stuff
