Implementation Guide
Note: To determine the number of flash drives to use, refer to the Design
Guide.
c. With Automatic selected, flash drives that will be used for creating FAST
Cache are listed in the bottom portion of the dialog box.
To select the drives manually, select Manual.
d. Click OK to create FAST Cache using the selected disks.
Note: If a sufficient number of flash drives is not available, an error message
appears and FAST Cache cannot be created.
e. Enable FAST Cache for the storage pool created for the solution.
 After FAST Cache is created, it is enabled by default for all new pools
created.
 To enable FAST Cache for an existing pool, select the FAST Cache
Enabled option under Advanced in the Storage Pool Properties dialog
box.
The FAST Cache feature on VNX does not cause an instant performance improvement.
The system must collect data about access patterns and promote frequently used
information into the cache. This process can take a few hours during which the
performance of the array steadily improves.
If the storage required for user data (that is, roaming user profiles or View Persona
Management repositories and home directories) does not exist in the production
environment already and the optional user data disk pack has been purchased,
complete the following steps in Unisphere to configure two CIFS file systems on VNX:
1. Create a block-based RAID 6 storage pool with the characteristics shown in
Table 10.
Create block-based RAID 6 storage pool Table 10.

The Design Guide describes the storage layouts.
2. Provision the required LUNs from the pool, as detailed in Table 11, to present
to the Data Mover as dvols of a system-defined NAS pool.
Configure LUNs for NAS pool Table 11.
