We are going to add several new arrays during the next few days and several new storage servers. We are now targeting smaller individual size with individual SSD caches to leverage more stable performance, and less effect on rest of the nodes.

Cache was fixed on the fly - infact, it was slowing down the array with too much activity being forwarded to the ssd drive.
After adding flashcache to one of the arrays it's performing extremely slow. It will be checked up on today.
It will lead to some nodes having downtime as we look into it, but we are hoping to keep it under 2hrs.
We will be adding several arrays today, and hopefully bringing a bunch of nodes into production today as well.
sorry took a little bit longer than expected, did some additional hardware level maintenance at the go.
Servers are booting back online, and we are now targeting that only downtimes for the next several weeks are data pool migrations.
