cheapo storage over ip over 10ge will always be faster than 2x8gbit FC? RRiiiiight.
So wait, a 10gigE port shared between protocols and with FAT IP overhead will solve the bottleneck issues of 2x8gig FC?
Yes I've seen slow SANs - but that's a design question, and why you should have designers.
If you think you can solve any big problems with a little SSD caching or - lets call it distributed and localized - storage tiers then this might scale to serve up all your servers. but for the ones needing performance, it will suck.
Much like virtualized servers, which does fine for 98% of the windows boxes, but once you migrate your big apps onto it you suddenly see users ordering the largest non-virtual iron they can get.
did I mention uplink and backbone bandwidth issues?
I think you guys need to get some reality or you drift up into the clouds.
I'm building distributed storage over DDR infiniband and I'm also a big fan of i.e. amplidata how also have a nice idea of local ssd caching. And when purestorage does some more selling, we will see a whole new level.
just this stuff is new, unproven commodity solutions.
Yes your performance will degrade if you got a by-the-book san and consolidated 150 servers onto one EMC. But that's not an FC issue. It was asking you asking for a bottleneck.
A SAN is a *NETWORK* and so it might be helpful to use it like one, with more storage systems, and not sending every unrelated bit of data through the core.
Just as it semt so natural to use distributed commidity crap storage with SSD cache, why don't you consider avoiding bottlenecks in your SAN?
Bonus: The SAN is really fast when you need it. Always, not just when you got the data cached and coherency is not needed.
