Your customer manages a print media environment, consisting of three Isilon clusters, which are out of support. The customer would like to have access to new software releases and feature sets. You have been asked to perform a full discovery of the customer's environment.
The customer's current Isilon clusters are as follows:
"Cust" (12 x 12000X) serves as upload media storage for different tenants.
"Working" (8 x 12000X + 6 x X200) serves as a working zone for extraction to RAW and printing media from it.
"Archive" (16 x 72NL + Accelerator nodes) is used to store printed content for six months.
The customer operates in a Windows environment using SMB 2.0, two DNS servers per AD forest, three forest domains which are servicing three different environments. All servers are operating on a 1Gb network, three VLANs segregating the DEV/QA/PROD environments. Currently, there is no monitoring in place for performance measurement or optimization.
The requirements for this solution include:
Better ROI and TCO

Maintain same performance with possible improvements

Renew HW/SW and get inclusive support

Limit migrations

Reduce space, power, cooling consumption

Get new feature sets

If migration required, use Parallel copy (multiple nodes, multiple threads, multiple connections)

Segregate tenant shares from other tenants

Expand up to 1PB of total storage

Which licenses need to be defined for the solution to perform optimally?
