That's not entirely true, is it?
Dimitris, we get it, your devotion to NetApp is commendable; but surely even you understand it's limitations - It's ok to like Engenio now, NetApp own them.
The FAS Series does have lots of speed, but the WAFL architecture and the copious abstraction layers before even presenting a LU is it's own downfall when it comes to sequential workloads - even NetApp as a whole recognised this; which is why they acquired the Engenio business.
The Engenio range is an excellent solid array, whilst not feature rich by any standards, it does it's work nicely due to the fact it is quite simply Traditional RAID Groups (or Volume groups) with LUNs (Volumes) without all of the overhead that comes with:
Nor does it have to find contiguous blocks in the same way that WAFL does.
As a side benefit; the Engenio also has a better fail-over function - that is, it's failover is near instantaneous (more akin to EVA, Clariion, AMS, Compellent) vs. NetApp with a 90+ second failover (or 120+ second without an RLM card) which I personally find interesting. (I've nursed more than enough WAFL checks to have no sense of humour on this subject)
So Dimitris, seriously buddy, I respect your right to an opinion, but you've got to get a sense of reality about the FAS range.
Seriously good hardware/software, but not suited to all workloads or environments, and neither is the Engenio (or anything else for that matter).
