Solution Integration and Product Configuration Overview
3 Network and Storage Planning This section contains pre-planning materials that the installation specialist can review with the customer before the NAS 8000 system arrives onsite. It includes: ■ System overview: a conceptual overview of the storage system of the HP NAS 8000 HA, including: — Storage Overview and Terminology — HA Storage Configuration ■ Planning worksheets to record the required network and storage settings for the NAS 8000 HA system.
Storage Overview and Terminology The HP NAS 8000 HA is an easy-to-manage storage solution for heterogeneous environments including Windows, UNIX, and Linux. The storage space on the HP NAS 8000 HA is made up of physical and logical storage: ■ Physical storage refers to the hardware used for data storage. ■ Logical storage is created by software that organizes your physical storage into file volumes and directories.
Directories Directories let you organize information. Directories contain files or other persistent data structures in a file system that contains information about other files. Directories are usually organized hierarchically and may contain both files and other directories, and are used to organize collections of files for applications or convenience. Snapshots Snapshots are an important part of data-protection plans.
High Availability The HP NAS 8000 HA solution includes a cluster, or group, of two NAS servers that function as a unified system. The cluster is managed by a Quorum server. The main purpose of high-availability clusters is to provide a higher degree of storage availability to client systems than is possible with a single server. This is accomplished by eliminating single points of failure and providing functional redundancy.
Data Protection RAID Levels Redundant Array of Inexpensive Disks (RAID) technology uses different industry-standard techniques for storing data and maintaining data redundancy. These techniques, called “RAID levels,” define the method used for distributing data on the disks in a logical unit (LUN). The storage arrays used in the HP NAS 8000 HA solution support the following RAID levels: ■ RAID 1+0. RAID 1+0 provides data redundancy and good performance.
HA Storage Configuration This section provides suggestions for configuring the storage on a NAS 8000 with high availability features. On a simple direct-attach NAS system without HA features, the simplest way to configure the storage is to create a single LUN for the entire array and create one volume group with multiple file volumes beneath it. However, in an HA cluster with two NAS Servers, each volume group can be active on only one NAS server, or node, at a time.
Figure 1 Single Array with One LUN and One Volume Group for Active/Passive Failover Figure 2 Single array with Multiple LUNs, Volume Groups and Packages Network and Storage Planning 11
Figure 3 12 Network and Storage Planning Multiple Arrays, LUNs, Volume Groups and Packages
Planning Worksheets The following topics should be reviewed in a planning session with the customer prior to installation. ■ Available disk space ■ LUN, volume group and file volume requirements ■ High-availability features ■ Network settings The planning worksheets in this section provide space to collect the information needed to install the system. The blank worksheets are also included on the HP NAS 8000 Documentation CD.

Tighten the two screws to secure the module. — Battery Module: Lift the module and slide it completely into the frame. Align the tab on top of the module with the connector inside the bay. Tighten the two screws to secure the module.
4. Connect the components to the Power Distribution Unit (PDU): a Connect the power cables of the components in each rack to the PDU strip on the rack as shown in the diagrams in “Solution Integration and Product Configuration Overview” on page 3. Note Each NAS server must be connected to a separate UPS. b Plug the PDU into the Power Distribution Panel (PDP) on the UPS. c Power up the components one at a time, in the following sequence, to minimize current inrush: 1. 2. 3. 4. 5.
5. Verify Array Configuration To ensure that your storage array(s) have been configured correctly, you must verify the array settings on all arrays attached to your NAS 8000 system. 1. Connect a laptop with terminal emulation software to the array. Connect an RS232 null-modem cable to one of the serial ports on the array. Figure 12 Array Serial Ports 2. Use a terminal emulator to log in and confirm the array settings.
6. Define Basic Network and HA Settings Configure the Quorum server The Quorum server is running with a Linux operating system. Use your standard Linux network procedures to assign an IP address to the Quorum server using either DHCP or manual IP addressing. Configure the NAS servers Before you can access the Command View NAS web interface, you must configure the System Management network port on both NAS servers. Note You will configure additional NICs using the Command View NAS web interface. 1.
4. Disable DHCP. The HA cluster uses virtual IP addresses – a concept not supported by DHCP. You must disable DHCP on all NICs that will be used for client communication with the NAS system. To manually disable DHCP on each NIC, execute: setNetworkCardDhcpEnabled eth0 F ... setNetworkCardDhcpEnabled eth4 F 5. Verify that HA is enabled: a Verify the authorization file is installed by executing: getSystemPackageList — If the result includes an entry similar to hpNasOs-HA-authorization, proceed to step b.
8. Define the DNS information. Execute the following commands, where: — XXX represents IP address information. — domain represents the domain name provided by the system administrator. setNetworkDnsDomainName domain setNetworkDnsAddressList XXX.XXX.XXX.XXX If no DNS server is available, or if you prefer not to use the DNS server, execute the following commands, where: — XXX represents IP address information. — *name represents the name provided by the system administrator.
