Swarm Storage supports standard x86-64 CPUs (Intel, AMD)
Single or multiple sockets supported (and multi-core)
Recommend use of above CPUs that include AES New Instructions (AES-NI) support
Used by Swarm for improved performance of Encryption at Rest (EAR)
Most modern server processors include this as of 2010

Best PracticeMaintain the same network speed for all devices within the Swarm cluster; mixing speeds requires additional configuration to avoid performance problems. |

InfoMultiport network cards (two or more ports per card) are not truly redundant when considering failover for the storage hosts. Multiport NICs experience common failure modes which that can disconnect a Swarm host completely. A true An 'active-active' design includes the use of separate NICs in the storage hosts to meet the requirement. |

Appropriate for functional design and testing
3 or more nodes (chassis) in a cluster
Can be deployed as virtual machines (VMware guests)
Rule of thumb, minimum physical memory is 2 GB + (0.5 GB * number of volumes), but more memory improves cluster operation
