Hi,

For the Isilon A2000, if I wanted to max out the cluster capacity of the array and I currently have 14 nodes using the 10 TB drives (280 drives total) ~2.73 PB, can I use the 16 TB drives on the remaining 238 nodes? Do I need to create a separate pool or can the existing pool be expanded?

Based on the specifications the A2000 supports the following:

Chassis capacity: 10 TB (800 TB), 12 TB (960 TB), 16 TB (1.2 PB)

Hard Drives Per Chassis: 80

# of Nodes per Chassis: 4

# of Chassis: 1 - 63

# of Nodes: 4 - 252

Cluster Capacity: 800 TB - 80.6 PB

Current Configuration:

Currently configured for 14 Nodes so I assume 238 nodes are remaining to reach capacity which if using the 16 TB drives should give me around 74 PB or do I have to stick with the 10 TB drives which will only give me ~46 PB? Does the cluster need to be the same drive size or can you use other supported sizes such as the 16 TB?

Thanks
