Description
Both IBM System Storage N3220 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 Fibre Channel (FC) SAN infrastructures
• High throughput and fast response times for database, email, and technical
applications
• 24 Serial Attached SCSI (SAS) 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 a maximum of 374.4 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 A12 to Model A22
N3220 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 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.
N3220 storage controllers are designed to interoperate with products capable of
data transmission in the industry-standard iSCSI, CIFS, FCP, and NFS protocols.
These include the IBM System p®, IBM System i® (NFS only), IBM System x®, and
IBM System z® (NFS only) servers.
Model A12 is designed to provide a single-node storage controller with iSCSI
support, and NFS, CIFS, and FCP support via optional features. Model A12 is a 2U
rack-mountable storage controller.
Model A12 includes:
• 2U, standard 19-inch rackmount enclosure
•
One 1.73 GHz Intel
TM
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) port
• Redundant hot-swappable, auto-ranging power supplies and cooling fans
Model A12 may be upgraded to a Model A22, however this is a disruptive upgrade.
Model A22 is designed to provide identical function as the Model A12, but with the
addition of a second processor control module (PCM) and the Clustered Failover
