Architected for Reliability and High Availability
The AX150 and AX150i consist of up to two active/active storage
processors and hold up to twelve 250 GB or 500 GB SATA-II disk drives.
They feature redundant fans, and fully redundant “N+1” power supplies
in a single 2U chassis. The dual-processor configuration is supported by an
additional 1U, UPS for maximum data availability.
SATA-II hard disk drives can offer improved performance over previous
generation SATA drives through Native Command Queuing (NCQ) which
uses advanced algorithms to execute commands in the most efficient
manner.
Connectivity Choices for Flexible Configurations
The AX150 offers up to four full-bandwidth, 2Gbps Fibre Channel host
ports and allows direct connection of up to four hosts or a single 2-node,
high availability cluster (two HBAs per server). With the addition of the
Brocade SW200E Fibre Channel switch, the AX150 storage system can host
storage for up to 10 redundantly or non-redundantly connected servers.
The AX150i offers up to four 1Gbps Ethernet host ports and allows direct
connection of up to four hosts or a single 2-node, high availability cluster.
With the addition of a Dell PowerConnect™ (or any industry-standard)
Gigabit Ethernet switch, the AX150i storage system can host storage for up
to 10 redundantly or non-redundantly connected servers. With the use of
free iSCSI initiators for Windows and Linux, the AX150i offers the most
affordable connectivity option available for a Dell/EMC SAN.
Redundancy Features Keep Your Information Available
The AX150 and AX150i feature mirrored cache, and hot-swap fans, power
supplies, and disk drives, to help assure continued operation in the
unlikely event of component failures.
One of the twelve hard drives can be dedicated as a "hot spare" to be
automatically incorporated into a RAID 5 or 1/0 RAID set should another
drive fail. Data in cache is written to disk in the event of a power failure.
Unlike data stored in battery-backed cache, data stored on disk can be
retrieved long after batteries are exhausted.
