Data Convergence and Storage
For the storage of the information we are gonna implememt SAN network, and is divided in two parts, the LAN Network and the servers (storage). SANs provide high availavility and robust business continuity for critical data environments. Are typically switched fabric architectures using Fibre Channel (FC) or iSCSI for connectivity.
How we can see in the previous topology, we want a Meshed SAN Architecture, that every storage unit being connected to each server via multiple SAN switches also called SAN directors which provide redundancy with the paths to the storage unit.
Also, we want to use Fiber Channel over Ethernet (FCoE) is a computer network topology that encapsulates Fiber Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds). FCoE operated directly above Ethernet in the network protocol stack, in contrast SCSI which runs on top of TCP and IP. As a consequence, FCoE can not be routed at the IP Layer, and will not work in routed IP networks.
In out datacenter we won’t use FCoE since Arista Networks (our network hardware company) because the don’t have switches with this feature. Despite this we have been looking what switches could we use to implement this network, and we have found the switch 7280R that provides the technology MLAG (Multi-Chassis Link Aggregation) that supports spine leaf and ECMP that allows to load balancing the traffic between different links.
Finally, this switch has 48 1/10GbE that we think that it’s enough for this network. Anyway, if we need more speed we can select other switch with highest speed port.
