Celerra 5.5.30 NS500 has these limits:

10TB FC per datamover
16TB FC+ATA (only 10TB FC)

forgot to mention that CX500 can take 7 DAEs (120 drives), so you have a lot more capacity available for fibre channel connectivity ..other then for use with Celerra.

So even though you can have a total of 120 disks, the total storage amounts on those disks can't exceed 10TB for FC and 6TB for ATA?

Can not exceed 10TB FC and 6TB ATA for NS500 running dart 5.5.30. Now if you upgrade your Celerra to 5.6.43 (latest code), Celerra will be able to utilize 32 terabytes per datamover (10FC+22ATA). This is how much NS500 Celerra platform supports ..even though array capacity can be much higher.

But still limited to 120 disks even with new dart?

DAE limitations are dependend of the backend, not the NAS/DART version

Hi Martin,

DART doesnt care about the number of disks - only about the usable capacity it sees

the 120 disks are a physical limitation of the CX500 Clariion - if you were using a larger Clariion or adding another one you could use more "disks" from the Celerra side

The mentioned Celerra capacity limits are qualification limits that I believe currently arent enforced by the code
You can find them in the Release Notes for your release in the "Capacity limits" section
Depending on your use case and workload you can ask EMC engineering for approval to go higher - that needs to be done through your local EMC team and an RPQ process

hope that clarifies it

Rainer was speaking of using more disks, not more TB per datamover.

Depending on the disk sizes, you could use more than 120 disks before you reach the 32 TB limit. Also the disks do not need to be used for NAS only ...

what do you mean you could use more disks ? Even if i have CX4-960 as my back-end storage ..NS500G can still only use 32T (published number). Is that a correct statement ?

Thanks guys this is all good information. I do have one other question relating to limits. We have 3 filesystems on our NAS each 1TB in size.

What is the maximum size of a file system you can create on the NS500G?
