VNX data flow

Hi All,

Am a newbie to VNX and we are in the process of purchasing 1XVNX 5700.

Q:

Since we have DART and FLARE, how does data flow?

Like a Celera is it - Network > DART > FLARE>FLare LUNs  (For NFS and CIFS shares)
and

Like a Clarion is it - host>SAN>Flare>LUNs  (For FC LUNs)

I humbly seek a detailed response to the same

Regards,

Ash

Hi Ash,

They are no big difference between the old fashion DART and FLARE.

VNX always use SP for SAN access [iSCSI, FC, FCOE] ans X-Blade/DataMover for NAS access [NFS,CIFS,MPFS]

DataMover is like a host so you have to give him access to the storage. Only BIG difference between NS series is that tou can use pool and the feature FAST.

Re: VNX data flow

Ok.

My understanding -

1. Host from SAN talk to FLARE>LUNs. They do NOT go throught the DART

2. Datamover is a like a host. So, DART speaks to FLARE and then accesses Storage

3. Thus it like a gateway model.

DART>Clariion>Flare>LUNs

AND

SAN>Clariion>Flare>LUNs

4. Hosts on SAN have no relation to DART

Please confirm.

Raghav

Re: VNX data flow

Thanks a lot.

Final Q: Is there any tool to move data from Netapp to VNX 5700? Am seeking a tool in lines of Open Replicator for Symmetrix.

Re: VNX data flow

i just checked E-Lab ..neither file nor block are supported to be migrated to VNX (SanCopy/Celerra Replicator) from NetApp, so you are looking at using host based migration tools.
