Question : Problem: WTF's up with my iSCSI network config ???
|
|
Experts:
I just purchased an EMC AX4-5i dual-SP SAN appliance; two racks, one for SAS drives and the other with SATA drives. I'm just setting up the appliance and I'm stuck, hoping you all can help me figure something out.
If you look at the attached file you'll notice my vanilla setup: 1 server with 3 NICs connected to a pair of GigE switches configured in a meshed network connecting a pair of SP units, each with two iSCSI ports of their own.
The problem I'm having is that on the server i can only ping one of two switches and only two of four iSCSI ports

No problem... glad to help. I actually envy your situation. You will accomplish A LOT and will be able to do it YOUR way! That's not always easy in large enterprises where many different tasks are managed by different groups and where decision makers are not always technically-savvy and sometimes end-up making the wrong choices.
Anyway, you will like the book I am sure... especially the checklists. They ensure you will not overlook anything.
<<Can I just purchase pre-terminated fiber cables that match the specs of the network?>>
You can certainly buy pre-fabricated fiber patch cables for the patch panel-to-switch connections. However, I don't think you want to use that in ceilings between wiring closets and obviously not between buildings as it would not comply to standards.
<<When buying Cisco devices, should I go directly to Cisco for the best prices?>>
Cisco does not sell equipment themselves. They use resellers like CDW, computers4sure.com, Insight.com, directdial.com, tribecaexpress.com, zones.com, PC Mall, etc. You can purchase equipment and SmartNet contracts from these outlets after you decide on a bill of materials. I think Cisco sales/engineers can help you with this however but I've never had the chance to use this approach before.
<<I will defintely look into Panduit when it comes to supplies. How do they relate to other companies in terms of price?>>
They are like Cisco, they use distributors. I've used Anixter before to buy some Panduit supplies but that was in very low quantity so I can't say about pricing.
