LUN Space

Jump to solution

I have couple of LUNs which has over 100GB available space and some of them VM's are already running in them as well, but my question is If I put a new VM in existing LUN which has 100GB space available, so will I run into any issue? I am sure I wouldnt, but I wanted to check with you to make sure it will not cause any problem with my existing VM's which are located in that LUN.

We are running high space in our SAN and trying to compress LUN's as much as we can.

Thanks.

you typically want to leave around 15 - 20% free space to allow for snapshot growth. Also, keep an eye on disk I/O. Just because a LUN has free space doesn't necessarily mean it's the best option.

I say continue to monitor your IOPS and you should be good, but still leave yourself some free space.
