MSDP 250TB

Hi

I have some questions about MSDP 250TB

can I have 32TB Disk and expand it later to 64TB then 96TB and so on in Windows and use crcontrol command to add it? I mean I use MSDP in my backup plan and then expand it. in dedupe guide says:

Before you can use the Media Server Deduplication Pool,you must add the other two volumes to the disk pool.

another question is this phrase: 8 mount points, each mount point must have a separate RAID group, a RAID 6 is recommended. 

in windows in a single drive how could I use 8 mount point with separate RAID group?

and it's interesting doc says: Recommended operating systems: ■ Red Hat Linux 7.5 ■ Windows Server 2012 R2 Datacenter 

Thanks in advance

Re: MSDP 250TB

1) present 32TB LUN to media server

2) apply a partition table (usually *not* MBR these days) to the LUN

3) create a partition to occupy the full LUN space

4) apply a file system to the partition - in your case NTFS

5) mount that new 32TB file-system at a specific location (as per previous post from Marianne)

.

For step 5... see a method here:

what's nested volume? and my question is can I deploy MSDP with 32TB and use it as a backup server and after a while I expand it to 64TB and so on?


You may want to read the article again?

You can start with 2 volumes - 1 x 1TB for MSDP Catalog, 1 x 32TB volume.
Then add more 32TB volumes as needed, following instructions in the article.

Nested volumes are described in the article - the volumes are mounted as folders under the same drive letter. 

Have a look at the example in the article :

.... each (32TB)  data# directory is a nested mount.
"c:/msdp/data1" ,"c:/msdp/data2" ,"c:/msdp/data3"
Catalog volume: "c:/msdp/cat" 

So, if you want to start with 32TB, you will just have c:/msdp/data1 and c:/msdp/cat as a start. 
When you want to add another 32TB volume, you will mount it as c:/msdp/data2 and use the crcontrol command to add the 2nd volume. 

For example:

C:\Program Files\Veritas\pdde\crcontrol --dsaddpartition c:\msdp\data2

Re: MSDP 250TB

You actually need multiple 32TB volumes and a 1TB volume:
 9 file systems in total - one must have 1TB storage space and the other 8 must have 32TB storage space each.

The volume used should be present as nested volumes on the same drive letter. 

Herewith detailed HOWTO doc. Skip to the Windows section:

Re: MSDP 250TB

Refer to the recently published  article on how to configure a 250TB MSDP pool on Windows and Linux.
https://www.veritas.com/content/support/en_US/article.100038442.html

This will tell you what is requireed and how to set it up.
If you have an existing pool of 32TB, you should be able to expand to 250TRB by adding the additional mount points.
