Isilon A2000 - Max out cluster capacity

Question

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

Hi, https://dell.to/3mbkHcX and https://dell.to/3arfw5K I believe smartpools will allow you to do it with mixed drive sizes.   Let us know if you have any additional questions.

Hello macyero, You do not mix drives of different capacities in your node.  This will cause issues when mixing drives of different sizes.

Hi Sam,

Just so there isn't any confusion. I currently have a 14 node cluster. If I add the remaining nodes using all 16 TB drives you are saying this could cause issues? So for future deployments would best practices be to use the maximum supported drives for your initial cluster creation?

Thanks
