Description

Both IBM System Storage N3240 models are designed to provide:

• High data availability and system-level redundancy to help address the needs of

business-critical and mission-critical applications

• Single, integrated architecture to support concurrent block I/O and file serving

over Ethernet and FC SAN infrastructures

• High throughput and fast response times for database, email, and technical

applications

• 24 Serial Advanced Technology Attachment (SATA) disk drives (via optional

features)

• Support for both block I/O via FC and iSCSI, and file I/O via CIFS, NFS, HTTP,

and FTP protocols

• Support for a maximum of 144 disk drives for up to 432 TB of physical storage

capacity

• Up to 6 GB of random access memory (per node)

• Optional 10 Gb Ethernet or 8 Gb Fibre Channel ports

• Two onboard SAS ports (per node)

• Upgrade capability from Model A14 to Model A24

N3240 storage controllers support the EXN1000 SATA storage expansion unit,

EXN4000 FC storage expansion units, the EXN3000 SAS/SATA storage expansion

unit, and the high-density EXN3500 SAS storage expansion unit.

These N series models are designed to provide fast data access, simultaneous

multiprotocol support, expandability, upgradability, and low maintenance. Additional

functions, such as snapshot, mirroring, and business continuance capability, are

available through optional licensed features.

N3240 storage controllers are designed to interoperate with products capable of

data transmission in the industry-standard iSCSI, CIFS, FCP, and NFS protocols.

These include IBM System p®, IBM System i® (NFS only), IBM System x®, and IBM

System z® (NFS only) servers.

Model A14 is designed to provide a single-node storage controller with iSCSI

support, and NFS, CIFS, and FCP support via optional features. This model is a 4U

rack-mountable storage controller.

Model A14 includes:

• 4U, standard 19-inch rackmount enclosure

•

One 1.73 GHz Intel

dual-core processor

• Up to 6 GB random access ECC memory

• Four integrated Gigabit Ethernet RJ45 ports

• Two SAS ports

• One serial console port

• One integrated Remote LAN Management (RLM) ports

• Redundant hot-swappable, auto-ranging power supplies and cooling fans

Model A14 may be upgraded to a Model A24, however, this is a disruptive upgrade.
