Higher Availability
InSpeed Embedded Storage Switches
improve system availability 20% by delivering
a very rich set of features designed to keep
storage systems active. These capabilities
are invaluable right from system setup by
performing intelligent pretest of drive drawers
and devices before they are inserted into the
system to eliminate situations where newly
added devices can disrupt a stable system.
And their intelligent health and performance
monitoring is continually collecting vital
statistics to predict failures and take automatic
corrective action to remove problem devices
from the system before they affect overall
system health; error types that affect as much
as 50% of known device failures.
Maximum storage system stability is achieved
with InSpeed’s unique Stealth Intelligent
Change Manager that gives unprecedented
control over embedded network interruptions
caused by health or configuration changes
sent by initiator and target devices. OEMs
can now pre–configure ports at the factory
to appropriately protect them from system
interruptions in their most effective manner.
And, InSpeed’s One-Step Zoning can be evoked
for flexible, dynamic hardware–protected
isolation between groups of ports within the
storage system; an important capability for
applications that require an additional level of
isolation from each other, whether temporarily
or permanently.

The InSpeed Embedded Storage Switch Model 350 is a 1U, half–
rack form factor 12–port non–blocking switch that is ideal for:
Embedded Root Switch In
Disk Storage Systems
Root Switch implementations place switched connectivity be-
tween the storage controller (or NAS head) and drive shelves
within a disk array for enhanced RAS capabilities and up to
3x performance while scaling improvements.

Fully Switched Infrastructure of
Root Switches & SOC–based SBODs
Fully Switched Infrastructures implement a Root Switch in
conjunction with Emulex InSpeed SOCs in SBODs to obtain
maximum RAS and up to 3x performance while scaling im-
provements, and up to 5x with the use of Automatic Trunking.
