AX4 is a versatile and cost-effective solution for organizations looking for an
alternative to server-based storage. The AX4 delivers performance, scalability, and advanced data
management features in one, easy-to-use storage solution.
Affordable and scalable
Advanced capabilities start with the scalability to meet the needs of today and the requirements of
tomorrow. Single-controller AX4 models are a low-cost approach to deploying external storage and
provide an economical storage platform for applications such as backup-to-disk and a variety of data
archiving tasks. Dual-controller models offer the superior availability, connectivity, and performance
that business-critical data and applications require.
Need more capacity and performance than 12 disk drives can provide? The AX4 can scale up to 60
drives through four expansion enclosures and up to 120 TB of capacity for headroom that will keep
users and applications in their comfort zone. The capabilities of the AX4 go beyond simply providing
generous storage capacity. With the ability to provide consolidated storage for up to 64 hosts, the
AX4 provides maximum flexibility for growing organizations that want to add servers and applications.
Well connected
With both iSCSI and Fibre Channel models, the AX4 enables organizations to choose a network inter-
connect that is right for their environments. AX4 iSCSI arrays provide the foundation for cost-effective
shared storage using widely available IP networking components for either direct-attach or for a net-
work using conventional Ethernet switches. AX4 arrays with 4 Gb/s Fibre Channel connections utilize
low-cost host bus adapters to provide cost-effective direct-attach configurations with a wide range of
SAN switch options to create SANs for up to 64 high-availability servers. Each controller supports two
front-end ports—either 4Gb/s Fibre Channel or 1 Gb/s iSCSI.
Tiered storage—mix it up
The concept of tiered storage is simple—having a range of storage types to match the storage needs
of the data. What makes this simple concept powerful is having the option to easily mix drives geared
for performance, as required by I/O-intensive applications, with those that deliver cost-effective
capacity for backup and archiving, among other needs. The AX4 can be equipped with serial-attached
SCSI (SAS) drives for performance-oriented applications and serial ATA (SATA) drives to deliver the
lowest cost per gigabyte and highest capacity per drive. The ability to mix SAS and SATA drives within
each enclosure provides the most flexible and economical system configurations for all needs.
The EMC CLARiiON AX4 series delivers functionality that unleashes the benefits of tiered storage.
Users can easily deploy, expand, and re-deploy storage with the AX4 series.
Users can migrate data seamlessly between different classes of drives and RAID types to deliver the
optimal combination of performance, availability, and economy. With CLARiiON’s unique virtualLUN
and metaLUN technologies, users are able to unlock the full capabilities of tiered storage, easily
