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
What would you recommend be done to consolidate the three clusters into one?

A.
• Expand the largest and most I/O intensive cluster using SmartFail
• Consolidate the remaining two clusters using Multithreaded version of RoboCopy
• Modify A-Record and propagate to all DNS servers to point to the new cluster

B.
• Leave the clusters as is
• Upgrade drive sizes to meet the customer requirements

C.
• Expand the largest and most I/O intensive cluster using SmartFail
• Consolidate the remaining two clusters using SyncIQ

D.
• Build a new cluster for consolidation
• Use SnapshotIQ to migrate the existing data onto the new consolidated cluster
• Spoof DNS to point to the new cluster
