Nearly eight years ago, I introduced All-In-One virtualized storage, first at STH
Time for a new idea:
napp-it Z-Raid HA vCluster
easy and cheap enough
I am on the way to finish my Z-Raid Cluster in a Box solution.
In the past a Cluster in a Box consists of two servers with a common pool of mpio SAS disks. One of the servers builds a pool from the disks and offers services like NFS or SMB. On a failure or for maintenance you can switch over to the second server within a few seconds. Management is done for example with RSF-1 from high-availability. SuperMicro offers special cases that can hold two mainboards
Such solutions are expensive and management is quite complex but offers high performance and high availability. To reduce costs, my solution is based on ESXi (any license) to virtualize the two nodes and a control instance. It uses the shared controller/ shared raw disk options of ESXi so my solution does not need multipath SAS but can work with any disks.
Setup see http://www.napp-it.org/doc/downloads/z-raid.pdf
If you want to try the preview state that allows a manual failover within 20s, you can update napp-it to the free 18.02 preview (or 18.12dev).
