asked on
LUN/Volume and Datastore Size.
This is my first time working with a SAN and want to just make sure I understand a few things before starting to carve out a bunch of LUNs and Datastores.
2 VMware Host running ESXi 6.0
SAN: Dell SCv2020
Usuable Storage: 12TB
The Dell SCv2020 actually allows you to create Volumes, which I have found out is also the LUN. I have read a bunch of good articles about if something happens to a specific LUN. I have read up on IOPS too.
What would be the best way to determine IOPS across these servers? We ran IOPS with Dell and they weren't that high.
I have the following server list:
Server1 - Running SQL for internal application - 500GB of data
Server2 - Running SQL for internal application - 1TB of data
Server3 - Primary DC - less than 100GB of data
Server4 - Backup DC - less than 100GB of data
Server5 - File Server - 1TB of data
Server6 - File Server - 1TB of data
Server7 - App Server - 100GB of data
Server8 - App Server - 200GB of data
See Diagram for my thought process on splitting the SAN into LUN's with the data above.
How would you split the SAN storage into LUNs?
Is it best to create the same size datastore as the LUN?
A LUN can be accessed by mutiple VMware host correct? It was weird that I have to assign the LUN inside the Dell Enterprise Console to a HOST.
The current infrastructure designed by the last vendor created 4 LUNs (2003 VM's, Linux VM's, 2008 VM's and Management VM's) What do you think about this setup?
I know that everyone has a different best practice so to speak but I wanted to hear some suggestions before I carve everything out.
