Connecting Cloud Innovators: Building Community at .NEXT 2024
Hello mates, We have 2x NX3350 and Arista switch which handle roughly 100 VM. Workloads are: 20x VM with heavy disk workload which are used mainly for reporting and analysis. R/W ratio is roughly 50/50. They created 20K IOPS workload when they lived on SAN storage with RAID10 and tiny flash tier and average latency was always below 5 ms. 10x VM which are used for application virtualization 70x VM which are use for desktop virtualization. Now, when we migrated to Nutanix, we have only 4K cluster IOPS and 20 ms latency which does not seems to be very good for us. Trying to resolve the issue, we enabled inline compression and increased CVM memory up to 20GB. We also tried to change tier sequential write priority. Unfortunately, this does not help. ncc, cluster status and prism health claim that everything is ok. Before we migrated our environment, we've run diagnostic VM and the results was roughly 100K IOPS for read. Here is the current configuration of cluster:NOS Version: 4
