We are currently looking at 655 GB - 1 TB network storage solution.
The solution must be Gigabit Ethernet attached, providing NFS version
3 (and hopefully inthe near future version 4) over TCP/IP. We also
hope to expand to 2-3 TB within 1.5 - 2 years in a attempt to
consolidate and provide further resources.
We are concerned with performance; reliability and single points of
failure; limiting factors in the filesystems and storage
units/hardware that effect expanding/shrinking filesystems; and
scaling multiple units in the future. We have been looking at the Sun
StorEdge 3900 series with a SunBlade 1000 providing NFS, and due to
EDU pricing, a Netapp F820 filer.
My primary role has only been network-based until recent, and what
really need to do in the end is simple -- provide software and data
access over NFS -- hence, the Netapp really makes sense to me.
However, we run a software package Cadence which requires a locking
daemon running on the NFS server. Netapp does have a proxy solution
in this case because big-guns like GM and Ford use this software on a
filer, but it does raise concern... will we confront a problem in the
future that we will have to live with because we are small/edu? We
have a good working relationship with Sun, but I'm not convinced
adding complexity (and less features from what I have seen) for our
simple needs will bring us much benfit, nor
I'm interested in people's experience (and limitations they have hit)
with these products, pointers to sites, and possible other solutions I
should look at.
Thanks in advance.
