If you haven’t got the solution you need, you can’t just do whatever you want. You need to escalate it.
You clearly work for a company where budget is unlimited.
A solution might already be available, but can’t afford to buy it (or justify buying it)
We need a proper storage solution, for our ever-increasing library of virtual images. A NAS chassis with loads of disks, sata controllers, RAM and RAID-Z storage would be the solution. Probably cost around £1.5k to deploy.
The most I can “buy” is a couple of 2TB disks, and install them in a 6 year old retired server, running FreeNAS.
