This is going to be a mercifully short entry. I’m saving the big one for another day
One of the features of NetApp storage is that by using Converged Network Adapters (CNAs) one can use a single wire and transport over that FC, iSCSI, NFS and CIFS, at the same time.
You see, since NetApp storage is truly unified, we don’t need cables coming out of 5 different boxes running 3 or more different OSes to do something (which is what, say, a certain competitor’s “unified” box is like – actually it’s even more boxes if one counts the external replication devices).
You might say “OK, that’s cool but how does it affect my bottom line?”
Just a few benefits that immediately come to mind:
- Far less cables to run in your datacenter for both storage and all the servers (each server needs 2 cables for redundancy vs 4 or more)
- No compromises since there’s no need to be forced to choose between iSCSI, NAS and FC – each server can happily use whatever’s best for the task at hand yet retain the exact same connectivity
- Less switches (no need for both FC and Ethernet switches)
- Less OpEx since it’s a simpler solution to manage
- Very high speeds (each link is 10Gbit) and low latency (FCoE is similar to FC – no need to do iSCSI if the same link can do both)
- Overall a far simpler and cleaner Datacenter
The other part is also important: Single OS. Inherently, something running a single OS has 3x less moving parts than something running 3 totally different OSes, regardless of packaging.
Here are some cool throughput results. Line speeds
One can dance around such concepts with marchitecture and fancy Powerpoint slides, but, in the end, just use your head. It’s pretty simple.
Food for thought…
