The EMC® CLARiiON® 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 60 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
interconnect that is right for their environments. AX4 iSCSI arrays provide the foundation for costeffective
shared storage using widely available IP networking components for either direct-attach
or for a network 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.
It allows users to 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 migrating, expanding, and reconfiguring their storage capacity to meet changing application
requirements. AX4 users can also easily expand existing disk pools and virtual disks as application
storage needs change.
Superior data availability and reliability
Leveraging Intel® Xeon® processors, the AX4 provides a flexible, reliable storage solution for your
business. The AX4 has inherited many advanced software capabilities that have proven to deliver
five-nines availability in CLARiiON midrange storage systems, including the CLARiiON CX3 series.
The efficient mirrored cache design on dual-controller models supports high performance as well
as availability. The AX4 provides continuous background disk consistency checking, enabling endto-
end data integrity. The simplified management and rebuild features of the AX4’s global hot-spare
technology enhance protection and maximize system dependability.
Advanced capability without the complexity
The AX4 delivers maximum capability in an entry-level system without adding unwanted complexity.
The system combines exceptional ease of use and intuitive manageability with the performance
and scalability that business-critical applications require. The AX4 also offers unmatched flexibility
with a choice of management environments and software solutions, enabling customers to grow the
capabilities of the system to match their changing environments.
Included software functionality provides ease of use
The EMC CLARiiON AX4 comes with Navisphere® Express, an intuitive user interface that simplifies
installation, configuration, and operation. The graphical approach to creating and managing storage
allows users to create and allocate new capacity in seconds.
And with built-in CLARiiON tools such as virtualLUN capability, users can easily and dynamically
migrate data to optimize performance and efficiency, all without application downtime. The AX4 also
comes with point-in-time snapshot capabilities and EMC PowerPath® path management software
with load balancing and path failover for high availability.
Optional advanced management and data replication
The optional Navisphere Management Suite extends the capabilities of the AX4 to meet the needs
of growing and distributed organizations. Navisphere Manager provides the ability to manage
multiple CLARiiON arrays, including AX and CX systems, from a single console. It also supports
EMC SnapView™ software, which is included with Navisphere Manager, for multiple point-in-time
snapshots as well as full-volume copies of critical data.
For Fibre Channel AX4 systems, the addition of EMC MirrorView™ software enables synchronous
or asynchronous data replication between arrays, maximizing data availability and enabling
comprehensive disaster recovery solutions. EMC SAN Copy™ software enables high-speed data
replication between AX and CX series models, as well as multi-vendor arrays for data migration
and edge-to-core environments such as remote or satellite offices.
To enhance these capabilities, the addition of EMC Replication Manager simplifies the management
and automation of the entire information replication process from the application layer, including
Microsoft Exchange, SQL, and Oracle, to the array for CLARiiON SnapView and SAN Copy software.
Most capable and affordable entry-level SAN for VMware
With iSCSI connectivity and integration with virtualized servers, the AX4 provides the most capable
entry-level SAN for VMware. A storage area network (SAN) featuring the CLARiiON AX4 will further
the benefits of VMware® deployments by supporting and enabling the powerful new features of
VMware Infrastructure 3, such as VMotion™, DRS, and advanced high-availability features. A solution
combining VMware with the affordable, simple, scalable, and reliable CLARiiON AX4 provides
enterprise-class capabilities and efficiencies in an easy-to-use storage platform.
Comprehensive interoperability support for multi-vendor environments
The EMC CLARiiON AX4 is the answer to storage consolidation for heterogeneous environments. It
supports Windows, Linux, AIX, HP-UX, Solaris, and VMware. The CLARiiON capabilities on the AX4
allow realtime volume expansion for new virtual machine creation. EMC E-Lab™ testing and support
resources ensure interoperability with host operating systems, HBAs, SAN infrastructure, and
clustering solutions.
Service and support
CLARiiON AX4 support options deliver choice and flexibility. Count on EMC’s world-class support
paired with maintainability and usability features to keep information available and operations
running. The AX4 includes a standard three-year warranty with 5x9 coverage (Enhanced support) for
next-business-day on-site response. Customers can also choose to upgrade to a premium level of
maintenance (Premium support) which includes 7x24 coverage with four-hour on-site response.
