Supported Operating Systems; Microsoft Feature Support; Linux Feature Support; Multiple Operating System Support - HP StorageWorks 500 - G2 Modular Smart Array User Manual

Supported operating systems

Supported operating systems include:
Microsoft®
Windows® 2000
Windows® Server 2003
Linux
Red Hat Enterprise Linux
UnitedLinux
For information about the most current operating system support, errata kernels, and service pack
requirements, refer to the HP website (http://www.hp.com/products/sharedstorage).

Microsoft feature support

Static LUN balancing enables the administrator to optimize I/O by assigning specific volumes to
specific paths in the storage system. If one path fails, the storage system moves volumes to the path
for the redundant HBA for I/O management.
Server-based PCI Hot Plug functionality supports online HBA addition and replacement.
Logical volume hot-add functionality supports online array expansion/extension.
ProLiant Storage Manager with the ProLiant Multipath Manager software and device manager
extension provide point-and-click multipath management.
Configuration flexibility enables boot volumes for DAS solutions to reside on the storage system.

Linux feature support

Static load (read-only) balancing enables the HBAs to optimize I/O with dual paths to the same
volumes in the storage system. If one HBA fails, the storage system moves volumes to the path for the
redundant HBA for I/O management.
Depending on the operating system, servers maintain boot volumes and enable greater storage
capacity on the storage system.

Multiple operating system support

For multipath configurations with multiple operating systems, use SSP to restrict HBAs from accessing
logical volumes containing data from a different operating system. For more information about SSP, refer
to the documentation that ships with the 4-Port Shared Storage Module.

Supported four-node configurations

The following sections identify supported multipath configurations with their respective 4-Port Shared
Storage Module connections and locations for boot and data volumes. These configurations require two
or three servers attached with four SCSI cables to the MSA500 G2 storage system.

Two-server external boot configuration

All boot and data volumes reside on the MSA500 G2 storage system.
