[c-nsp] Cisco Switch Packet Buffering Matrix?

[Arie Vayner (avayner)]

Skeeve,

If you want to get this info in the "right" way, then the best approach
would be to talk to your local Cisco account team...
Some of the info may require NDA etc.

On the same point, you may want to also look at 4948E and Nexus5000
switches, which could give you better latency performance, which is
important for storage-related applications.

I don't think this email got through the other day... I didn't see it
appear.

Hey all,

I am doing some iSCSI implementations are the moment and are looking at
which switch models are best for different iSCSI rollouts we're doing.

I am wanting to know which 29xx and 35xx/37xx series switches have the
following:


-          Size of packet buffering per model

-          If the PB is per port or shared

-          Is there one or more classes of PB classification

-          If the PB is shared, is it per switching module (i.e. 8/12
port block) or across the entire switch

-          If the 10GB model is plugged in, does it have its own PB, or
does it share the main boards?

I looked in the Portable Product Sheet -
http://www.cisco.com/web/partners/tools/quickreference/index.html  but
found nothing, and Google and Cisco.com proved useless.  Maybe there is
a reason for this, or my searchfoo is weak.
