Looks like an ipod... This is going to be interesting in the long term. Those Cisco chassis can do some expending though so you may be able to get to a more reliable system with what you have.
Actually UCS can't really expand much from a storage perspective. They don't have any native DAS JBOD support, and the MegaRaids on them they do little in integration or customization. UCS was never really designed to use local storage in RAID I'm convinced (at scale anyways). They are useful if your using them in true JBOD (VSAN, they are certified for use) or with HBA's to talk to an external disk array.
Definitely not designed for that use.
Other thing is get some training. There's some rookie mistakes lurking in that config that scare me about other things...
http://vmware.stanly.edu is the poor mans path to a VCP. Grab a copy of mastering vSphere. The HA deep dive book is free now if you know where to look. and increasingly we'll have storage and availability documents lurking at storagehub.vmware.com

This is true... But getting some training is rarely a bad thing. 8-)

Alright, so I'm going to need to fix some DNS issues which I think @JaredBusch informed me of yesterday. When I perform
nslookupon my file server and printer server it kicks back an error stating:DNS request timed out.
Default Server: Unknown
Address: 192.168.10.16 <-- IP of my domain controller (2003) -

I agree. Training and documentation are key once this fire is fully out.

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.
