Infortrend All Flash Array Storages deliver lightning speed performance and enable users to optimize SSDs and energy efficiency. It also provides all the benefits of SAN, NAS and Cloud Gateway storage together in one single system, making it the ideal choice for enterprise applications (such as database, virtualization, video editing, file sharing, backup, and cloud data integration). For hardware, all flash array storage features a 2U-25bay form factor, flexible host boards to choose from, and stable, reliable modular design with high expandability; as for software, it comes with complete data services and simple, intuitive management interfaces.

Flash Protection & High Availability (I)
 Symmetric active-active controllers
for block device
 Hosts can access the same LUNs simultaneously
via dual active controllers, enabling more
equally distributed workloads and effectively
minimizing costly path management time
 Cache protection technology
 Mirrors data cache between controllers with
super-caps destage to flash, keeping data ‘alive’
in the event of a power loss.
 Super capacitors with flash module provide
effortless maintenance Symmetric Logical Unit Structure

earsed
2 new pages (I-J) are ready to write,
but there is not enough space to
write these 2 pages. in order to write
to the pages with stale data (A-B), all
good and invalid pages (C-H, A'-D')
are read and written to a new block
Y then the old block X is erased. C
(invalid) and D (invalid) page will still
be read and written to another block
is because SSD do not aware that
