We host a lot of websites and need a lot of fast storage for those websites and our Cloud Infrastructure. We currently run a lot of individual iSCSI devices over Gigabit Ethernet. We want to consolidate those individual iSCSI devices in to a centralized unit that is comprised of Hybrid storage (SSD+HDD) that is expandable to support a large amount of drives with redundant connections to our Cloud Infrastructure. › Continue reading
Building a ZFS SAN to scale up to hundreds of drives and several enclosures takes a lot of fore-thought. Also important in that decision is figuring out what kind or RAID levels you expect to be using, what kind of drives you will be using, and what kind of performance that you need.
We will discuss component selection including Chassis Selection, Motherboard Selection, Processor Selection, CPU Selection, Cooling Selection, Memory Selection, SSD Selection, Hard drive selection, Infiniband selection, and HBA selection.
We will also focus on the performance of the ZFS SAN using different ZFS RAID levels, and different failure modes.
