EMC Clariion AX150 Dual FC 4x750GB AX150-750 Data Sheet

With available iSCSI and Fibre Channel models, the AX150 enables users to choose the
network interconnect that is right for each environment. AX150 iSCSI arrays provide the
basis for cost-effective shared storage using readily available IP networking components
for either direct-attach or for SAN connectivity using conventional Ethernet switches.
AX150 Fibre Channel arrays can be connected to local servers with low-cost Fibre Channel
fabric host bus adapters (HBAs) to provide a simple direct-attached shared storage solu-
tion. With the addition of one or more fabric switches, up to 10 servers per array can be
supported.  

Each AX150 can support up to 10 hosts and 256 virtual disks (or LUNs), and the dual-controller
AX150 models support up to 20 initiators for 10 high-availability host connections. EMC

for AX150 software provides enhanced data availability and performance

through path failover and load balancing in high-availability installations.

The AX150 family includes two models that support a range of application requirements,
deployments, and scalability needs. The single-controller AX150 provides a low-cost
RAID solution that includes key data integrity features, such as RAID 5 and RAID 1/0 data
protection and battery-backed cache, and is ideally suited for customers beginning to
implement network storage. 

With two front-end host ports, the AX150 single controller can support two direct-
attached servers or up to 10 network-attached hosts connected through a switch. The
AX150 features 512 MB of processor memory with battery-backed cache to protect
against data loss in the event of an outage (for up to 96 hours). CLARiiON RAID technology
combines efficiency with availability and protection against data loss in the event of a
disk drive failure. With hot-swap disk drives and power supplies, the AX150 is simple for
users to maintain, while redundant cooling fans and the option of a second, redundant
power supply provide an extra measure of reliability.

The dual-controller AX150 provides dual active storage processors, mirrored cache, and
dual power supplies to deliver high availability and end-to-end data protection to sup-
port business-critical applications.

Dual storage processors, dual hot-swappable power supplies, and N+1 redundant cool-
ing result in superior availability, data protection, and integrity. An available rackmount
UPS (required with the AX150 dual-controller models) allows the array to destage data
from cache to disk in the event of a power failure. The operation of the UPS is fully inte-
grated with the AX150 to provide a graceful shutdown of the array in the event of a power
outage, further enhancing data protection and recovery. The dual-controller AX150 pro-
vides high-availability storage for up to four direct-attached hosts or two host clusters or
for up to 10 fabric-connected servers in a department. 

The AX150 family provides support for SATA II disk drives, providing the highest disk
capacities, cost-effective performance, and advanced data integrity features. SATA II pro-
vides faster 3.0 Gb/s data transfer to and from the disks as well as Native Command
Queuing (NCQ), which streamlines sequential data transfers. SATA II technology results
in significantly improved performance for I/O-intensive applications such as messaging,
