SAN STORAGE

Superior Dependability

Fully redundant

•

system architecture delivers 99.999% availability

Active-active controllers

•

provide highest performance and

dependability in a multipathing environment

Snapshots and replication

•

enable data protection

Self-healing

•

, patented

of RAID rebuilds by 30%-50% and reduces HDD failures by fixing

hard drives before they fail

Catches silent data corruption

•

of both SAS and SATA drives that

is not detected by other systems

RAID groups span enclosures

•

for maximum reliability

Global hot spares

•

and hot swappable hard drives

Mirrored ECC cache

•

is also battery-backed

Background disk & cache scrubbing

•

prevents applications from

receiving corrupt data

High Efficiency

Thin Provisioning

•

enables smart capacity over-provisioning,

keeping drive costs to a minimum

Both FC and iSCSI

•

connectivity is ideal for making the transition

to an IP-based storage infrastructure

SAS and SATA intermix

•

in the same enclosure can economically

store both primary and secondary data

Power off RAID groups

•

when not in use to save energy

Wide Scalability

Expand RAID groups

•

dynamically by adding HDDs one-by-one or

many at a time while data is still being accessed

Up to 144 HDDs

•

in a single RAID group

Grow LUNs online

•

without reconfiguring RAID groups

Use 8 front-end ports

•

to attach more servers without a switch

Up to 8 GB cache

•

provides top performance for multiple hosts

Command Line Interface (CLI)

•

allows automated control

Email notification and SNMP traps

•

proactively alert you

Browser-based GUI

•

allows remote management of up to 32

arrays in a ‘single pane of glass’

NEC D4 Storage

The D4 SAN storage array delivers both high performance 8 Gbps

Fibre Channel ports and cost-effective 10 Gbps iSCSI connectivity

block-storage applications. It uses SAS and SATA drives in the

same enclosures to create a tiered storage architecture.
