Does Celerra can support replicator via mirrorview/a over iSCSI

Hi Dennis,

Celerra replicator does not support Mirrorview/A over ISCSI.

No, celerra does not support the Mirrorview, and iscsi is used only for presenting the iscsi LUN to the host.

But you can use the remote replication in Celerra as well, I am sorry I was not able to understand your requirement of using the mirrorview in celerra, can you please elobarate.

Regards

Sameer

what are you trying to achieve?

Is there any doc for that?

Celerra does support MirrorView/S for a box-failover (complete Celerra) solution for a long time now

Dennis,

Could you confirm, what do you mean by "mirrorview/a over ISCSI"

Hi,  Naveenkumar :

I knew that Celerra Replicator can support mirrorview/s before, but not sure can support mirrorview/asyn.

And unify storage can use mirrorview on iSCSI link for DR purpose.

So I would like to confirm that we can use Celerra Replicator via mirrorview/a on iSCSI link.

It may not good way to use this configuration, it should use replicator only via network.

my english is not good, so sorry for confusing.

Still not sure how to understand this.

Celerra does only support Mirrorview/S, no Mirrorview/A.

If you want to use Mirrorview/A, than you can not use this for data hosted on the Celerra.

Celerra Replicator is tranferring its data over the IP-Network, using a datamover interface.

If you are asking if you can do mirrorview/a of non Celerra luns (a CX Lun, which is not used by the Celerra) using a CX iSCSI interface, than I do not know the answer.

Hi Dennis,

Celerra does not support Mirrorview/A.

When you are using the term ISCSI, do you mean to say volume based replication?

Hi, Naveekumar:

I'd like to do filesystem replication.

The original requirment and thinking is do filesystem replication at low bandwidth environment.

We may get high replication rate by MirrorView technology, and not sure Celerra Replicator can get good performance result.

So I mentioned MirrorView/A before.

It's my fault, so confusing you.

I think it's correct to use Celerra Replicator and fulfilling the replication via network.

I have no idea about the details of Celerra Replicator on MirrowView/s link.

It may do lun base replication first and then assign luns to remote storage group.

Maybe it can automatically identify the LUNs, become Celerra filesystems.

appreciate your help.

If you would like to do a file system replication, You can go by Celerra replicator (V2).

The replication rate depends on the available bandwidth between the two sites. In V2 replication, you can schedule the bandwidth utization also.

To understand how Celerra works with Mirrorview, I will upload the document on Using Mirror View Synchronous with Celerra for DR document.

The section on system requirement and restriction should be good enough to give you an idea of Mirrorview on Celerra.
