Lousy Disk Storage = Lousy Disk Storage Quarter
From the top...
IBM's high end is 5 years out of date.
The mid range is lacking in critical functionality when compared to HDS, EMC, 3PAR and other mid-range products.
XIV is largely a joke.
SVC is funtionally good, but too expensive for many customers.
N series (rebadged NetApp) is more expensive than the NetApp version, so why would anyone but IBM's flavour?
Flames, because someone @ IBM needs to light a fire under their storage portfolio before this market is lost to all but the most die-hard IBM shops.
