Nexus 3064-X switches for high load storage multipath iSCSI traffic

Hello dear community members,

 

We have two switches Nexus 3064-X and we would like to build a new iSCSI SAN. Expected iSCSI storage performance is 30 Gig iSCSI-A + 30 Gig iSCSI-B

My questions:

1) can Nexus 3064-X handle such workload?

2) in general, what is iSCSI requirements to Ethernet switches? I know only about few: Line rate forwarding and MTU 9000+

3) Which Cisco nexus switches you recommend for CRITICAL VMware infrastructure + iSCSI storage

 

Thank you.

Thank you for your reply

 

What is advantage of 5K versus 3K in this particular case?

We don't need FC/FCoE capability that 5K provides.

We don't need advanced Ethernet features like FabrichPath/VXLAN/etc

Switches will forwarding only STORAGE traffic, not LAN

All what we need is to have 2 switches = 2 vlans = 2 separated iscsi paths:

 - iSCSI-A: "blade servers ---> Switch A ---> storage"

 - iSCSI-B: "blade servers ---> Switch B ---> storage"

 

Nexus 3K "not designed for this purpose"? Is it "out of this scope" to deal with iSCSI and storage connectivity?

 

 

 

Personally, nexus 3K and 6K designed more of low latency kind of setup ( personally never deployed iscsi on nexus 3K)

 

Nexus 5K UP (unified ports ) deployed many in various enviroment and  have DC deployment CVD recommend them.
