General Information for AX150
Configuration Rules: AX150 Storage Systems
Note: In this document, array means storage system.
A total of 10 servers are supported per storage system.•
A total of 10 Host Bus Adapters (HBAs) are supported on single−SP AX150 storage systems.•
A total of 20 HBAs are supported on dual−SP AX150 storage systems.•
A total of 4 storage systems per server are supported.•
A total of 256 virtual disks per storage system are supported.•
User installable HBAs are limited to the Emulex and the QLogic E models.•
HBAs from different manufacturers cannot be mixed in the same server.•
User installable switches are limited to the QLogic SB3050−08A−E and the QLogic SANbox SB1404−10AJ−E, the Brocade DS−3250−VL2E and the
Brocade DS−220B−FF−D, DS−210B−DEU and the DS−210B−DE. Pre−configured zoning or the Zoning Wizard must be used with these switches to
be user installable. All other supported switches are not user installable and require professional installation.
•
Switches from different manufacturers cannot be mixed in the same SAN.•
If an AX100 series system is connected to a server, no other type of storage system can be connected to that server.•
A server must be connected to a storage system either directly or through a switch. A server CANNOT be connected to the SAME storage system
both directly and through a switch.
•
All direct connect configurations are user installable.•
For example, figures 1 and 2.•
Any switch configuration utilizing an Inter Switch Link (ISL) is not user installable. No more than 2 switches can be connected with an ISL.•
For example, figures 14 and 15.•
In any supported multiple−server configuration, the servers can run the same operating system or any combination of supported operating systems.•
The snapshot feature requires that the source and secondary servers are connected to the same SP. As a result, the snapshot feature is not
supported for figures 4 and 5.
•
PowerPath must be installed on all attached servers for all configurations.•
A clustered configuration requires one or more HBAs per server and a single−SP or dual−SP storage system.•
2 to 8 nodes are supported in a clustered configuration.•
All nodes in a cluster configuration must run the same operating system. Diagrams may show other operating systems, but dissimilar operating
systems cannot be clustered.
•
All nodes in a cluster configuration must be connected to the same SPs.•
For example, figures 2, 7 and 8.•
The installation of an operating system on a storage system for the purpose of booting the server from the storage system is not a user installable
option.
•
Boot from a storage system on clustered servers running Windows 2000 require a dedicated boot HBA.•
Boot from a storage system on clustered servers running Windows 2003 DO NOT require a dedicated boot HBA.•
Backup Device Support
EMC's testing and qualification responsibilities only apply to SAN (switch) attached backup devices. SAN attached backup configurations include a backup
device connected to a port on the switch. These configurations are not currently user installable. Please refer to the EMC ESM for SAN attached backup
supported configurations.
For tape devices connected directly to a backup host, EMC strongly recommends that the component vendors' supported configuration matrices are reviewed
(host configuration matrix for compatibility with SCSI or Fibre Channel interface used to connect to tape device, tape device vendor for compatibility with
selected SCSI or Fibre Channel interface and backup software vendor for compatibility with the tape device).
Path Definition
A path is a connection between an HBA port and a target SP port in a storage system. Each HBA that is directly connect to, or zoned through, a switch to an SP
port is considered an initiator of that SP port. An HBA port can be zoned through different switch ports to the same SP port or to different SP ports, resulting in
multiple paths between the HBA port and an SP.
Remote Replication
For customers planning to utilize the AX150 along with CLARiiON arrays running EMC SAN Copy software, adding SAN Copy/E software to the AX150
provides the ability to replicate data from the AX150 via Navisphere. For example, using the AX150, SAN Copy/E can be used to replciate data from branch
offices back to the data center to provide disaster recovery protection and to consolidate the backup process. The SAN Copy/E application on an AX150 is
qualified for connectivity to the CX arrays running SAN Copy (for the SAN Copy application only, not host attach) through professionally installed switches listed
on the AX Support Matrix. For cost effective remote replication solutions, as well as low cost DR implementations, the QLogic iSR6142 SAN Router has been
qualified.
