A customer is asking me about ISE VM storage performance requirements. The documentation states the following:
"The storage system for the Cisco ISE virtual appliance requires a minimum write performance of 50 MB per second and a read performance of 300 MB per second. Deploy a storage system that meets these performance criteria and is supported by VMware server."
The customer, or more specifically the customer's storage team, is asking if this is a "sustained" requirement along with the questions below. Is there any published or best practice info regarding specific IO performance for ISE that I can share with them?
Avg Read Latency Requirement: < ?ms
Avg Write Latency Requirement: < ?ms
Peak Read Latency Requirement: < ?ms
Peak Write Latency Requirement: < ?ms
Avg IO Size: ?
Write to Read Ratio: ?
Read Throughput: 300 MB/Sec (Is this sustained?)
Write Throughput: 50 MB/Sec (Is this sustained?)
Avg Read IOPS: ?
Avg Write IOPS: ?
Peak Read IOPS: ?
Peak Write IOPS: ?
Would the devices function as Active/ Passive or Active/ Active?
Would the above workload requirement be the sum of both sites or would the characteristic be for each appliance running concurrently?
