I am estimating hardware configuration for customer environment but hesitating how should I configure the disk.
My reqirements are
2500 evt/sec (Maximum)
58 TB of logs ( holding for 1year )
5 shards, 1 replica for each index.
I am considering to split into 3 nodes which ends up with about 20 TB / node.
Considering the size of storage, I want to use 4TB 7200 RPM NL-SAS with RAID 1 + 0.
However, I assume that 20 TB of NL-SAS RAID 1 + 0 will require long recovery time
1491 hours (100 IOPS per disk , 5 disks per node )
May I ask for advice about how should I configure my node and disk in this case? I would appreciate any advice.
