Building New Core Network for 10Gb iSCSI SAN - Recommendations
Posted on 2013-11-10
I wonder if anyone can help me specify some new switches for a new project I'm working on.
I have been given the chance to build a new server and network infrastructure, so want to make sure its done right.
I will be installing a SAN a HP P2000 G3 10GbE iSCSI along with a few HP DL380s with 10GbE.
For core switching I wanted to go modular and have selected the HP 5406zl (J9866A).
For edge switching to the desktop I've selected 2920-24G Switch J9726A with HP 2920 2-port 10GbE SFP+ Module (J9731A) as they fit the budget. I'm looking at 4 2920s at present.
So the plan would be to have 10GbE iSCSI trunks to the servers and SAN and 10GbE data trunks from servers to core switch.
And 10GbE SFP+ fibre trunk between the 5400zl and 2920-24Gs HP 8-port 10GbE SFP+ v2 zl Module and using HP 2920 2-port 10GbE SFP+ Module (J9731A) over 50/125 OM3.
First off, is this a compatible configuration?
Second, can I apply different VLANS to the 2920s so I can:
1) Separate desktops from printers, with desktops getting one ip range from dhcp and printers getting another.
I know printers are notorious for generating lots of chatter, so I want to keep them separate.
Is it a case of ip helpers on the VLANS pointing to the dhcp server.
2) I'd like to use a 10.x.x.x class of address, but subnetting is not my strong point.
The site is never going to have more than 20 servers, 30 printers or 80 desktops.
I'd like servers in one range, desktops in another, and printers in another.
There are also 20 VPN users would I'd like in a different range.
Some recommendations on this would be gratefully received.
