NO kidding.

I miss 90% of the stuff that's written on the weekends.

That's the one time I normally keep up best.

@wirestyle22
Things to do.
Replace the core switch with 1 GB or better
Fix DHCP so it gives out two DNS hosts
Make sure both (or more) DNS servers are working/syncing -

Less normal daily work I'm guessing for you. I'm just not on the computer or phone much on the weekends.

So what was the status of this from yesterday?
- IPOD
- VM Restored and powers on
- Still having DNS/DHCP issues?

Replace the SAN.Replace, or re-engineer the storage?

ReplaceRemove the SAN.FTFY

ReplaceRemove the SAN.No, that is not the correct solution.

Well the issue with that is that it's a major change. That's a great idea, but it's a major change and one he is not prepared to do. Replacing the SAN is a drop in replacement and he could move from a device that isn't plausible to use in a scenario like this to one that is. It's a huge amount of money, but that's a spend that they committed to before he was there. Moving to an HDS, EMC, 3PAR or Nimble is a drop in change that would fix a lot of things.

it's a plan that the previous IT was committed to. Management only because they were probably sold a bill of goods because they put their trust in the wrong person. But we don't actually know any of those details.

I'm interested in hearing why these would make a good alternative to the SAN and IPOD?

I have read this entire thread (albeit over a lot of time) I don't know the piece of equipment "IPOD" as it is referenced in this thread. I figure it is not an Apple device. Could someone clarify?

An IPOD is an architectural system design. Where you have 1 storage node (usually a SAN) and two servers. The entire setup is configured so that the servers sit up at the top, with no storage capabilities, and the SAN at the bottom.
Often the two servers are connected together with two switches and then the servers are connected to the single SAN.
The term IPOD means Inverted Pyramid of Doom, the term refers to the fact that if the connection to the SAN or the SAN its self goes belly up, you lose all functionality of the system.
It's a commonly sold design because it has huge profit margins, two compute only servers, the switches, and the SAN.

If he can't get away from a SAN architecture, I'd highly recommend the Nimble storage units. We have them here, and they rock, big time!

They aren't an alternative for SAN, they are SANs. The thinking here is that architecturally there would be very little work to install a SAN from one of those vendors (these are known good SANs) into his current setup.
The best solution considering what we know about @wirestyle22 environment would be for him to migrate away from VMWare (cost reasons) to XenServer or Hyper-V (both include vMotion/storage vMotion for free) with local storage. Sadly his Cisco servers apparently aren't a good choice when considering local internal storage, so moving to new servers would probably be advised.
I would consider contacting xByte specing out two newer'ish servers with enough local storage Install XS or Hyper-V and migrate.
The major concern I've heard in doing this is that since @wirestyle22 works for medical, his medical software vendor might not support XS or Hyper-V. If this is important to him, then he could stay with ESXi on the new host servers with local storage.
But damn.. He definitely needs to replace that 100 Mb switch he has at the core of the network.

This is probably the first thing he should do. Falls way below the home line and would be an inexpensive upgrade to gigabit.
