Hellocommunity, I needa recommendationfor configuring aFAS2552HA.Webought aFAS2552HAwith the following equipment, 20x600GBSAS-discsand4x200GBSSD,withclusteredDataOntap8.2.2RC2. We want to configure oneVserverforCifswith about50concurrent client sessions and one VserverwithiSCSI/CIFSforHyper-V /SQL andwithabout 70concurrentSQL-client sessions.Howshouldthe aggregates beconfigured?
I see twopossible configurations.
1. creating one Flash-pool aggregatewith6datadisks and the ssd-discs forHyper-V /SQLonnode1and one aggregate with4datadisksonNode2forCIFSclientrequests.
2. one singleFlash pool aggregate with12datadisksfor all services.
What wiil be the more suitable configruation? A largeaggregatesdue to higherIOPS, or2aggregatesforbetter loaddistributionbetween nodes?
as you will need two root aggregates, 6 disks will be lost (2x raid4 and 1x spare for each node).
with only 14 disks left I would configure just one aggregate and use the second node just for failover. I don't know if flashpool can make up the loss of performance of having only 7 disks in the aggregates if you create one for each head.
