@donaldlandru said in ZFS Based Storage for Medium VMWare Workload:
My next biggest concern, like any technology, is how do I get there from here. I have enough budget for a storage node, and we are going to run out of space within the next 60 days. I do not have, and will not receive additional funding this year for new servers. So some form of "in-place" style of upgrade has to occur. Obviously, this is a server down, convert vm bring it back up type of process that has an unknown LoE.
So when someone says "You will not get more funding" you need to reply "You will not get more IT for no spend". Apply quota's to the file servers, implement aggressive archiving cut back vCPU and memory allocations so your cluster can fail over, quota mailboxes on Exchange and in general "enforce" their "no new budget policy". Turn on FSRM reporting and post reports that show who's using the most space (Dump similar reports from Exchange). Don't let things hit a wall and crash, start putting the breaks on growth. IT is not a magyver episode where your expected to conjure IOPS and capacity and RAM from thin air.
Trying to not paint a picture of a rock and a hard place, but realistically where else am I at right now?
Your not between a rock and a hard place they are. Follow the rules above, and they will either find you capital to invest in so they can continue to use more storage and compute, or they will agree that its not worth the spend. THIS IS NOT YOUR PROBLEM. Your problem is to quantify what it will cost to deliver x and deploy if funded. It is not your job to be given an arbitrary budget and produce y. I remember when I realized this, and my job became a lot more Zen like. "Do what you say you will do" was my old office motto. Because of that people said no a hell of a lot.
