Celerra gets 10 Gigabit Native iSCSI plus much more (Part2)

Posted: January 12, 2010 in Celerra, VMware

I recently posted about some of the changes to EMC’s Celerra unified storage system, if you missed part 1 you can view this here and for everyone else as promised here is part 2.

As previously noted in post 1, all information was found on PowerLink, if your an EMC customer and you havent already done so, I highly recommend getting an account.

Celerra Manager IE8 Support

Celerra Manager has been a bit behind the times in regards to support for Internet Explorer, its great to finally see IE8 supported.

Fast Mount

I actually plan to do a post shortly on Celerra DataMover (now called X blade) failover and cover some of the considerations when your setting up your Celerra in production, so keep an eye out for this in the near future.

What is Fast Mount ?  

The improvements in DART V5.6.47 will reduce the file system mount time significantly for a typical configuration. The file system mount function is a major part of the reboot and failover processing time. Configurations with larger numbers of file systems will benefit even more.

Manual Deduplication management API and CIFS compression 

What manual options are now available for using Celerra deduplication?

With DART V5.6.47, an API has been introduced to enable external management applications to call the deduplication process for specific files. Currently CIFS file level compression functionality in Windows Explorer is the only interface used for this manual function.

How is the CIFS compression functionality enabled?

In Windows Explorer, if a user right clicks a file, specifies properties and selects “Advanced”, there is an option to “compress contents to save disk space”. If the client file is on a share that is hosted by Celerra running 5.6.47 and with to With DART V5.6.47, an API has been introduced to enable external management applications to call the deduplication.

Replication Enhancement “Out of Family” support

Reading over the information I found on PowerLink, it suggests earlier versions of DART supported replication (using Celerra Replicator) between the same major DART releases e.g. 5.5, 5.6, but in reality when you contact the Celerra support team I can say from experience they want to see identical versions of DART running on both Celerra’s.

 Now with “Out of family support” EMC will support phased upgrades of systems on different major releases e.g. 5.5, 5.6. This is to allow for upgrades in environments with multiple systems involved in replication and it is not feasible to upgrade all platforms at the same time.

It’s important to note this functionality is supported from 5.6.47 and above only.

Windows 2008 R2 iSCSI support

As you would expect this did in fact work as expected but was previously unsupported, I’m glad to see Windows 2008 R2 is now fully supported.

SMB2 Support

The SMB2 protocol is now fully supported with 5.6.47 which is great news for Windows 7 and Windows 2008 users which utilises the new protocol, it’s also worth noting that you can run SMB2 exclusively or run both SMB1 and SMB2 together.

As noted above with the iSCSI support, SMB2 with windows 7 and Windows 2008 works as expected in earlier DART versions but its great to see EMC getting these things “supported” as nothings worse than sitting in front of a customer and having to say it works but its not supported.
