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, or both.
• Device Manager extension provides 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 feature support
• For multipath configurations with multiple operating systems, use Shared Storage Presentation
(SSP) to restrict HBAs from accessing logical volumes containing data from a different operating
system. For more information about SSP, see the documentation shipped with the 4-Port Shared
Storage Module.
Supported four-node configurations
The following sections discuss 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. lists the boot volume and data
volume location for the two-server external boot configuration.
