Emc celerra file locking

Multiprotocol batch jobs failing since migration to Unity from VNX due to file locking. Unity uses a different default policy for locking in Multiprotocol environments, this can affect some operations that previously ran on VNX and used the VNX default nolock locking policy for Multiprotocol environments.

NFSv4 has the lock management integrated in the protocol itself, but may also be advisory or mandatory, depending of the implementation. A locking policy property is used to define the alternate behavior. You can select one of the following locking policies for a multiprotocol file system: Setting Description Mandatory Default Uses the SMB and NFSv4 protocols to manage range locks for a file that is in use by another user.

Many of the files stored on the Celerra are large and deduplication will result in cost savings for the KIT with the benefit of faster access to the files. Unified storage is clearly an area where customers are getting this value as well as increasing the operational efficiency of their environments. By consolidating VMware, Windows, Linux and Unix environments onto a single Celerra NS system, IT managers gain a tremendous amount of flexibility and the ability to deploy and update the latest storage technologies across all application environments as needs dictate.

The new Celerra systems continue this tradition and integrate numerous innovative new capabilities, at no additional charge, into a single, easy-to-use system. As with the previous generation, the new easy-to-use Celerra NS models are customer and partner installable. No Locking option C.
