MirrorView /S with CLARIION Flare 30 Gotcha

I’ve been working on a storage project over the last few months and I ran into a problem with MirrorView /S which turned out to be a bug in the CLARIION flare code. I thought id write a quick post about it incase anyone comes across the same problem. The Problem : The symptoms I saw were as [...]

Removing “EMC-SNAS” comment on Celerra CIFS shares

If you’ve ever configured CIFS shares on your Celerra before (VSA included) you’ll know when mapping to the shares using Windows 2000, XP or Server 2003 you get the default CIFS server comment added in windows explorer. The comment will display as “EMC-SNAS:T<Dart Version>” shown below as “EMC-SNAS:T6.0.36.4“ To stop this from happening you can typically handle this two ways. [...]

Celerra and Clariion Login Gotcha with Unisphere

In the last couple of months I’ve deployed two Celerra NS120′s and a Celerra VG2 gateway for which I experienced the same problem preventing anyone from being to login to Unisphere post install. The symptoms with the NS120′s was quite different to that of the gateway, the NS120′s gave a clear blatant certificate error which let you know the certificate was not valid [...]

Whats all this Unified Storage HOOEY about ?

I was talking to a friend last week who asked me two provocative yet valid questions, and I thought It would be worth posting about because at the end of our conversation he had opened his mind to a few concepts he had not considered. Question #1   “Whats all this Unified Storage Hooey about?”  Probably a good place to [...]

Celerra DART 6.0 with Clariion FLARE 30 GOTCHA

I’ve been deploying Celerra’s for a while now and with technology changing as fast as it does, you really need to be across the applied practice, best practice and NAS Matrix documents found in PowerLink to validate your storage design. For the last couple of years the majority of the Celerra’s Ive deployed have been shipped with DART 5.6 code [...]

Replication Manager 5.3 brings support for NFS on Windows VMware Proxy

Since Celerra NFS datastores have become supported by both Replication Manager and VMware Site Recovery Manager, I’ve been migrating Celerra customers off iSCSI to NFS mainly because of the overhead needed to facilitate Snapshots/Replication of iSCSI luns. In versions prior to 5.3 you needed to have a Linux host configured as the VMware Proxy to allow snapshots of NFS datastores, but the [...]

EMC Replication Manager 5.2.3 with a couple of Celerra fix’s

I’ve seen a number of times recently a scenario where a Replication Manager jobs starts to fail with an error indicating the Celerra file system holding the iSCSI lun is full. The cause of the problem is Replication Manager fails to clean up a failed snapshot, when the next job runs it fails because there is no longer [...]

iSCSI or NFS with EMC Celerra ?

There has always been a lot of debate in the VMware community about which IP storage protocol performs best and to be honest I’ve never had the time to do any real comparisons on the EMC Celerra, but recently I stumbled across a great post by Jason Boche comparing the performance of NFS and iSCSI storage using the Celerra NS120, you can [...]

EMC Celerra FAQ’s

Over the last couple of months Ive had a fair number of questions from readers wanting to know more about the EMC Celerra, there are a few common questions which keep coming up so I thought it would be worth doing a post to try to answer some of the FAQ’s.  Does Celerra support EFD (Solid State) disks ?  Absolutely !
