Personally, I think Netapps SSD offerings were just to add another tick in
the box when comparing their capabilities with EMC.
I thought Netappıs strategy was to increase performance by:
1. Changing their OS so that NFS scales better by using more threads
2. Offering the ability to massively increase cache using add-on cards so
disks are used far less.
3. Offering scale-out solutions where data can be striped across filers.
Thatıs obviously a far cheaper way to get performance and, at least in the
short term the sales patter is likely to be without bias (because we can
offer SSD too), weıd recommend you buy our PAM modules instead and if that
isnıt quick enough then SSD is an optionı.
Mind you, an OnTap 8 24 node cluster with SSD and PAM would probably be
pretty rapid ;-)
