NAS b3000 v2 - Quick Start Guide (326190-002)

Product Overview
20 NAS b3000 v2 Quick Start Guide
The NAS b3000 v2 is configured at the factory with default system and storage
parameter settings via the pre-loaded customized NAS operating system.
However, storage included with the second model is not pre-configured, allowing
the NAS administrator to tailor the organization and configuration of the storage
to specific environmental needs.
With MSA1000-based storage, the NAS administrator uses the included HP Array
Configuration Utility (ACU) to manage the hardware storage. With the VA-based
storage, the NAS administrator uses the HP Virtual Array Configuration Utility to
configure the storage. The Logical Disk Manager (LDM) included in the NAS
Operating Systems is utilized to manage the logical storage regardless of which
storage system is in use.
NAS b3000 v2 as a Clustered Pair
Note: Do not connect SAN storage enclosures until the SAN connection tool has been
completed inclusive of all configuration steps and software loads that the tool
prescribes.
In the clustered configuration, two NAS devices are linked via a private network
and have access to shared storage as illustrated in Figure 2. In the example, each
NAS device is attached to the MSA1000 storage enclosure via a pair of fiber
channel HBAs and two external SAN switches or two embedded switches on the
MSA1000. Similar configurations exist for VA deployments as do MSA1000
deployments. Dual HBA per NAS device is recommended, but not required for
cluster deployments, since dual HBAs allow for path failure without causing node
failover in the cluster.
The cluster setup for the NAS b3000 v2 requires at least three logical unit
numbers (LUNs). One LUN is required for the quorum disk and two LUNs are
required for data storage. Individual data storage specific to each node is required
for the proper setup of file sharing where both nodes participate in file-sharing
activities. Clustered NAS systems have the ability to provide redundant
active/active access to file shares on disk. However, as with all Microsoft-based
clusters, the unit of ownership among nodes is at the LUN level. Therefore,
individual file shares can be accessed by only one node at a time based on which
node owns the LUN.
For clustered NAS b3000 v2 deployments, it is important that the LUNs in use by
the cluster follow the guidelines pointed out later in this chapter in the Storage
Management section.
