5.5.1 Predefined Multi-HBA / RAID Zoning Configurations
There are three predefined Multi-HBA and Multi-RAID zoning configurations for the Ultrastar Serv60+8 that
are enabled at the manufacturer. The Multi-HBA portion of the configuration assists in providing better
performance by allowing more than one HBA to connect and manage the system. The Multi-RAID portion
of the configuration simply allows the main drive bay to connect to multiple HBAs. Each Multi-HBA/RAID
configuration is predefined to allow the system to perform to a specific set of zones.
Each configuration allows the user connect a different number of HBAs that have access to a set number of
drives. Each of these drives are part of a grouping called a zone group. This section displays the necessary
information related to each of the predefined Multi-HBA/RAID zoning configurations.
Dual HBA/RAID Zoning Configuration:
The Dual HBA/RAID Zoning Configuration allows up to two HBAs to view a specific zone group of drives.
Each host will be able to view up to 30 drives that are mapped to both HBAs. Each zone group will display
all of the devices that are contained within that zone. If a drive slot is not populated, it will still be part of
that zone group, but it will not display any results in enclosure management until the drive slot has been
populated. In this Configuration, the enclosure is divided into two zone groups as shown in the image
below represented by two different colors.
