[gpfsug-discuss] Flash for metadata

[Marc A Kaplan]

"I assume that creating several smaller LUNs on each FlashSystem in the 
same failure group is still preferable to one big LUN so we get more IO 
queues to play with?"

Traditionally, more spindles, more disk arms working in parallel => better 
overall performance.

HOWEVER Flash doesn't work that way... So it's going to depend... 
Perhaps some kind soul can point us to some information about this and how 
much it varies among today's flash based storage products.
