Best Practices for Building a Virtualized SPARC Computing Environment

o Enterprise Manager Ops Center can create, resize, delete, and
clone LUNs. A dynamic block storage library can be created if an
Oracle’s Sun ZFS Storage Appliance is discovered and managed by
Enterprise Manager Ops Center.
This best practices guide discusses considerations for both iSCSI and FC SAN setup
and use, but it is recommended to use dynamic storage libraries based on Oracle’s Sun
ZFS Storage Appliance wherever possible.
Dynamic Storage Library Configuration
This best practices guide describes how to create a storage library for guest metadata
using iSCSI LUNs from Oracle’s Sun ZFS Storage Appliance. In addition, the Sun
ZFS Storage Appliance offers a unique capability in Enterprise Manager Ops Center
to create and resize LUNs as needed.
Sun ZFS Storage Appliance Setup
Details of setting up and configuring a Sun ZFS Storage Appliance can be found in
the product documentation available in Oracle Unified Storage Systems
Documentation.
For the best performance and reliability, use dual storage controllers with clustering
enabled and configure IP multipathing and jumbo frames on the network devices.
Enterprise Manager Ops Center requires the presence of Storage Connect workflows
in the Sun ZFS Storage Appliance. Those workflows are part of the appliance kit
necessary to set up an iSCSI Target and iSCSI Target Group within the Sun ZFS
Storage Appliance and then include these names in the Enterprise Manager Ops
Center’s discovery profile. More details on the procedures to set these up can be
found in the guide Oracle® Enterprise Manager Ops Center Discovering a Sun ZFS
Storage Appliance and Configuring Storage Libraries.
Enterprise Manager Ops Center Discovery of Sun ZFS Storage Appliance
After the Sun ZFS Storage Appliance is configured, use Enterprise Manager Ops
Center to discover it. The detailed steps are provided in the Enterprise Manager Ops
Center document referenced in the previous paragraph. Ensure that the discovery
profile has the iSCSI target checked and that the Plugin Specific Information field
contains the iSCSI Target Group and iSCSI Target values that were set up on the
storage appliance. It is also possible to select the NFS target in the discovery profile,
thereby enabling creation, management and use of NFS shares from within Enterprise
Manager Ops Center. No plugin-specific information is required for the NFS target.
Execute the Add Assets action using this discovery profile and when job completes, a
new dynamic library is available in the Dynamic Block Storage section of the Libraries
navigation accordion. This library allows creation or deletion of LUNs, shows existing
LUNs, and allows them to be resized. As described later in this guide, it is also
possible to use this dynamic storage library as the source for LDOM guest disks, in
which case the LUN is created at the time the LDOM guest is created.
