Welcome back to SAN array land, Oracle. Larry Ellison's company has reinvented its Pillar Axiom 600 SAN array as a hybrid flash/disk array, the FS1-2, with auto-tiering and noisy neighbours sorted.
It is a general-purpose hybrid array but tuned for Oracle software. Calling its new storage box the Flash Storage System (FS1), the Big O has honed in on EM's all-flash XtremIO as its competitive focus, even though that system has no disk storage. The FS1-2 should more properly be compared with hybridised enterprise-class arrays from all the mainstream storage suppliers - EMC VMAX/VNX, NetApp FAS, HP 3PAR, etc. - as well as hybrid arrays from Nimble Storage, Tegile and Tintri.
