Dell NX3610, NX3500, NX3600 manual Example NAS Volume Creation Scenarios

various data access patterns. The security style can also be set to Mixed which supports both POSIX security and Windows ACLs on the same NAS volume.

•Quotas: Different quota policies can be applied to different NAS volumes, allowing the administrator to focus on managing quotas when it is appropriate.

Example NAS Volume Creation Scenarios

The following scenarios provide examples of how NAS volumes can be created to meet the needs of an example organization with the following conditions:

1.The average read/write mix is 80/20 and the average hourly change rate for existing data is less than 1%.

2.The departments and NAS volume requirements are as described in the following table:

Department	Securit	Snapsho	Replicatio	NDMP	Number	Read/	Hourly
	y Style	ts	n	Backup	of	Write Mix	Change % of
					CIFS/NF		Existing Data
					S
					Clients
Post Production	NFS	Hourly	No	Weekly	20	20/80	1%
Administration	CIFS	No	No	Weekly	10	50/50	None
and Finance
Broadcast	Mixed	No	No	Weekly	10	90/10	None
Press	CIFS	Daily	No	No	5	10/90	5%
Marketing	CIFS	Daily	Yes	No	5	50/50	None

Scenario 1

Create NAS volumes based on departments. The administrator logically breaks up storage and management into functional groups. In this scenario, the departmental requirements are quite different and support the design to logically create NAS volumes along department lines.

•Advantages:

–It is logically easy to manage the NAS volumes.

–The NAS volumes are created to match the exact needs of the department.

•Disadvantage: The NAS volumes become difficult to manage if the number of departments in the organization increases.

Scenario 2

We recommend grouping departments that have similar security requirements into NAS volumes. The administrator creates three NAS volumes: one for NFS, one for CIFS, and another for mixed.

•Advantage: The NAS volumes work separately between Windows and Linux.

•Disadvantage: Unwanted services may be provided to certain departments. For example, if the CIFS volume is backed up weekly for the administration and finance departments, the press and marketing departments also get backups even though they do not require it.

Scenario 3

NAS volumes can be created based on the feature (snapshots, replication, NDMP backup, and so on).

•Advantage: The NAS volumes are created to match the exact needs for each feature.
