That's the kind of situation where blades can make sense. For general use, unless you have crazy space requirements, up until about 8-12 servers, at least, I wouldn't consider them. At a pay-per-U datacenter, that could make sense.
Yes, we've used NetApp SANs for NFS/iSCSI. I've also seen good results with many other brands of storage enclosure. Even QNAP has a decent storage system at reasonable prices. Blade systems CAN simplify cabling (unless you still need a ton of uplinks). The HP c7000 system was pretty easy to manage, but we had issues with the management cards in both chassis. Over time ping to the OAs would get longer and longer until they quit responding and the onboard administrators had to be reset. We had the issue with C7000 acquired in 2008 and another in 2010. HP, of course, said "We've never seen this before". We just accepted it as normal, eventually, and did a failover of the OAs, primary to secondary, and rebooted them about once a month. That was non-disruptive to the workload. HP's converged networking makes a lot more sense to me than Cisco UCS's (acquired 2013). Overall, the blade system increased the price, left us constrained on things like memory slots and ability to put in PCI cards and local disks.
