SAN Storage problem in Vsphere 6.5

Hi, yes it has 24 disks, we set them to 2 volume, 10 TB each.

Is there any procedures we should follow to successfully expand the disk? Does it require down time for server?

Expand what disk and where ?

As Andrew says you can just add a disk enclosure to the MSA. It is trivial for the first additional enclosure since you just tie it onto both expansion ports. A bit more complicated when there is already an expansion enclosure attached to preserve the "top-down / bottom up" redundant connectivity but even then it can be added live with no downtime if you know what you are doing.

@ Andrew: I mean expand the SAN storage with that enclosure. Does it require downtime?

@ Andy: do you know the reference link / any documentation for procedures of mapping the enclosure?

https://support.hpe.com/hpsc/doc/public/display?docId=c03823462 , use the Fault-tolerant cabling (left) rather than straight-through bur admittedly for a single additional enclosure both layouts are the same.

You can add the enclosure live "Fault-tolerant cabling allows any drive enclosure to fail - or be removed - while maintaining access to other enclosures." implies that. I've added enclosures live to previous MSA versions, they complain a bit when adding a third or fourth enclosure as you temporarily break one link to insert it but they keep going as there is a redundant path, you just get a few redundant path down warning emails.

Hi, I got these steps on some Internet sites, are they enough?

1. Mount enclosure to SAN storage via SAS cable
2. Create a new disk group on SAN Storage
3. Add disk group to current pool
4. Expand current volume
5. Expand datastore on VMware GUI

looks a good plan

Hi,

+1, plan looks fine.
If you manage to extend the actual RAID array/storage pool and LUN the datastore is on, you will have the option to expand the existing datastore without downtime.

For 1 unit of D2700, it supports maximum 30 TB of storage, am I right?

It depend on drive type - I've read 12.5TB

But this one stated that it can support up to 30 TB?

Depends on the document you read, and drive type you use...

I've read two different documents from HPE...

https://tdhpe.techdata.eu/Global/documents/13404_div.PDF?epslanguage=en

This one confirms 30TB. (but the doc is 5 years old!)

But the fact that most pages are not available on HPE, suggests End of Life ?

(but agan states 12TB)

Hi Andy, so how many TB should we have if I purchase D2700 and 25 sff SAS drives 1.2 TB? Please give reference.

Hi, sorry to come back, but because D2000 and D2700 is EOL, so which one should we use?

Is MSA2050 Disk enclosure possible?

You mean you can;t buy a D2700 any more?

The EOL notice lists  Q1J07A as the replacement SKU, which is indeed a MSA2050 SFF disk enclosure. Better than D2700 as it's 12Gb rather than 6Gb but takes one less disk. Sorry, I pasted the wrong part no from the EOL/replacement SKU list previously.
