Hello, sandwich fans! It’s been awhile since I’ve written, but I have some fresh deli meat for you today. If you recall, last year I wrote a blog post about setting up VMware, Synology, and iSCSI MPIO. It turns out to have been my most-read post so far, for which I thank you. Since I’ve gotten such positive feedback, today I’m going to show you a similar setup, but this time I’m going to use NFS instead of iSCSI.
There are some pretty significant differences between iSCSI and NFS, both in terms of architecture and performance. One big difference is that NFS really doesn’t have support for multi-pathing (MPIO) in the way that iSCSI does. It has a few work-arounds like using alternate subnets and so forth, but for today we’re going to rely on simple failover on the host side with LACP link bonding on the storage side. Later on, we’ll compare the performance to the iSCSI system we built last year.
