== Hardware recommendations : Hyperscale ==

=== Nodes ===
* For single cluster minimum of 3 storage nodes are recommended.
* To scale performance and capacity , add storage nodes to hedvig .
* Node should be added in multiples of 3
=== CPU and Memory ===
* Servers should be dual socket E5/E7 with on board storage, Jbod are also supported but in Jbod or Raid0 mode.
* Hedvig is optimized for scale out. It is preferred to add storage node then to add storage to single server.
* The minimum memory configuration for each physical server for a Hedvig Cluster Node (non-hyperconverged) is usually 48 GB.
Typical deployments use servers with 128 to 256 GB.

=== Network ===
* 10G network for internal network and 1 G network for management.

===Drives ===
* No limitation to any drive SAS/SATA/SSD
'''Note''': It should be yet to be verified that SAS 12Gbps will have any advantage as storage tearing is in place.

== Hardware recommendations : Hyperscale ==
* In hyper-converged architecture , storage and compute scale together on commodity servers.
* Hedvig recommends separate controller for VM (hypervisor ,vm storage and client side cache) and Storage.
* One drive, for a datastore for the Hedvig VMs (that is, the Hedvig Cluster Node VM and Hedvig Storage Proxy VMs).
* Additional drives, which are dedicated to the Hedvig Cluster Node and which should all reside on the second controller that can be passed through to the Hedvig Storage Node VM.

== Storage node ==
* Two SSD are used for metadata commitlog and Hblock commitlog and data.
* Further SSD are used server side cache , auto-tiering
