MSA 2050 Volume not matching with ESXi 7

[LaithA]

I have a MSA 2050 with 2 Pools of the same config. RAID 6 with 8 drives in each Pool and 2 Global Spares. ! VDG in each Pool. I have created 1 volume in each VDG. These volumes on the MSA are 7.190TB. When I search the Host for a new Datastore is finds both volumes but shows that they are 6.5TB. Why am I missing 600GB per volume?

Hello,

It looks like you may be looking at the datastore with two different units of measurement. 
Because 7.19TB equals 6.5TiB 

I hope this helps.

Thanks for responding. The Server with VMWare7 shows the available storage to create a New Datastore as 6.54 TB. The HPE MSA 2050 shows the volumes I created as 7190.9GB. I was hoping you were correct so I double checked the sizes and this is what is shown. I would post pictures if I could figure out how

Hi,

Operating systems usually show volume size in base 2. (TiB,GiB)
MSA uses Base 10 as the default. (TB ,GB)

1TB = 0.909 TiB

MSA reports size in TB by default whereas ESXi reports size in TiB

7.19TB converts to approximately 6.5TiB.
You could use any online TiB to TB calculator.

You could change MSA settings to show values in Base 2 or TiB.

Log into SMU (Web management interface of MSA), click on system > Actions > System settings.
Select Manage Users
Select the user account to which you are logged in.
Base 10 would be selected by default.
Select base 2 from the drop-down box.
Click on Apply and close.
Log out of SMU and log in and check the volume size values.

You were correct. VMWare shows TB but means TiB. They make it very confusing by doing that. Thank you for your help!

I'm glad everything worked out.

Cheers!

Thank you for the reply. This was the issue. Not sure why VmWare 7 shows TB when they mean TiB. That really throws a lot of confusion into the available storage. Thank you!
