# From Aaron: 37 PB storage
Currently operating a cluster of 14 servers, each with 168x 18TB drives for roughly 37PB of raw capacity. I've had multiple drives fail across the cluster and within a server without any impacts.
The biggest issue I've encountered is that some of the maintenance tasks are single volume at a time and as such take a very long time to complete across the cluster.
Initially deployed servers with each disk having a single volume service but later updated and changed the deployment to using 4 disk RAID 0 per volume service. This increased single threaded throughput dramatically and impacted rebuilding and moving volumes positively.
Each 1U server has 2 Seagate 5U 84-bay SAS enclosures attached.
