HUGE PERFORMANCE FOR HUGE DATA

Complements SSD and HDD

New flash enclosure contains up to 12 flash modules

Shared resource to SAN

‒ Like HDD and SSD

‒ Unlike server-side cache

Flash module drives

‒ 1.6TB per flash module

‒ All flash enclosure will scale to 19.2TB

‒ Up to 8 flash enclosures – more than 150TB of flash!

HITACHI ACCELERATED FLASH STORAGE

1.6TB per flash module

Up to 8 flash enclosures per system –

maximum 154TB

12 modules per 2U enclosure – 19.2TB
