This is what our tagline of Simply Faster means. The performance is there, and is simple to use.

and on the JR4
[root@jr4s ~]# cat /etc/exports /data 10.1.0.0/255.255.0.0(rw,no_root_squash,async,no_subtree_check)
Caching impacts not relevant, as the 69GB is larger than both the JR4 and DV4 ram, and the disk on the JR4 feeding this DV4 over NFS is so much faster than the fabric, that storing it in ram wouldn’t do much, even if you could fit it all in.
No tuning on the 10 GbE cards, this bit rate is roughly half what they can do. Will be working to get over 1 GB/s NFS later on this weekend.
