Celerra

The Celerra is multiprotocol NAS head that can be attached to an EMC Clariion to provide SAN access via CIFS, NFS, or FTPS. The OIT-ISO-PROV group is building a storage service (and price point) around using this instead of accessing the SAN via Fibre Channel.

One of the primary features of the Celerra is the ability to create CIFS servers and join them to AD domains.

Quirks:

• Access Based Enumeration (ABE) has to be enabled on the back end.
• Shadow Copy has to be enabled on the back end.
• File Filtering (by extension) has to be enabled on the back end.
• Quotas must be managed using a command-line tool from EMC.
• While the shares on the Celerra "server" can be used for DFS Roots or leaf nodes, NTFRS/DFR-R are not supported.
• The first share on the "server" must be created on the back end (and it comes with some *nix-y folders that automatically get created within it). You can create additional shares inside the first one, but you do not have access directly under C$ to create any. You also will need to type in the share paths since it won't let you browse inside the original share.
• When using the MMC Share snap-in to set NTFS permissions (not share permissions), you will be disabling inheritence of NTFS permissions. It is recommended to change the permissions by mapping higher-level share and setting them there.

GPO Support: The Celerra "server" will update its Group Policy every 90 minutes (need to double check) to update certain settings:

• Security Settings
• Audit Policy
• Restricted Groups??

The information that OIT needs if you wish to use the service:

 Amount of storage (current pricing is <$1300/year)
 FQDN of the "server"
 Shadow Copy Enabled?
 ABE Enabled?
 AD Group that will be assigned permissions
 Name of the 1st share you want on it

Support models:

• Support it yourself (OIT Creates is, gives permissions, you move it to your OU, and you deal with it)
• Helpdesk Supported (more info once the HD is trained)
