Product FeaturesThe NetBackup 5000 has the following features:
■ Large capacityA single node supports a maximum of 16-TB capacity , and two nodes supporta maximum of 32-TB capacity .
■ Smooth expansionThe NetBackup 5000 supports online single-node expansion to improve thestorage capacity and backup performance of the whole system. Two nodessupport a maximum of 32-TB capacity .
■ High reliabilityThe key components such as fans and power supplies are redundant. Thebackup data is protected through RAID 6. Multiple disaster recovery policiesare provided to prevent data loss resulting from damaged devices. Global hotspare disks are provided. If a disk fails, a hot spare disk is used to replace thefaulty disk and reconstruct the backup data.
■ High securityThe NetBackup 5000 provides the data encryption function to preventunauthorized data access, thus improving data security.
■ Easy managementWith the Web-based management interface, the NetBackup 5000 can easilyback up and recover data,monitor system software andhardware, andmanagefault alarms.
■ Energy savingsThe NetBackup 5000 is configured with high-efficiency power entry modules(PEMs), fanswith intelligent speed control technology, and optional low-powercentral processing units (CPUs). These allow the NetBackup 5000 to meet theusers' requirements on low consumption. The NetBackup 5000 uses theintelligent dissipation technology to reduce the power consumption duringthe normal running of the device. The NetBackup 5000 uses the optimizedvent to reduce the noise and the power consumption of the device.

ChassisThe chassis provides the following functions:
HardwareChassis
20
■ Integrates all modules into one environment
■ Facilitates the heat dissipation for all modules through the venting and holesin the chassis
Figure 2-5 shows the appearance of the chassis.
Figure 2-5 Appearance of the chassis
Disk module functionsThe disk module has the following functions:
■ Hosting the OS. The OS of the NetBackup 5000 is installed on the system diskthat is in slot a and slot b.
■ Providing storage capacity. The NetBackup 5000 stores the system data onthe systemdisk. TheNetBackup 5000 uses the remaining unoccupied capacityon the system disk for backup storage.
Disk module componentsA disk module consists of the handle, disk tray, SATA disk, and SATA conversionboard.

Disk type, dimensions, capacity, and rotational speedThe NetBackup 5000 supports a maximum of 24 hot-pluggable SATA disks.
The height, width, and depth of the NetBackup 5000 are 175 mm, 440 mm, and685 mm respectively.
The NetBackup 5000 supports SATA disks with the capacity of 1 TB at therotational speed of 7200 rpm.
System diskThe disk in slot a and slot b are the system disks. See Figure 2-2 on page 15. forthe location of slot a and slot b.
■ Donot remove or insert the systemdisks. These actions candamage the systemdata.
■ Do not use the system disks as hot spare disks.

MainboardThemainboard is in themiddle of theNetBackup5000 chassis. It processes servicesand provides inband and outband management functions.
The following external ports and internal ports reside on the mainboard:
■ One management network port
■ Two service network ports
■ One VGA port
■ One system serial port
■ Two USB 2.0 ports
■ Two PCIe x8 slots that are used to connect the RAID card and NIC

RAID cardThe redundant array of independent disks (RAID) controller (hereinafter referredto as the RAID card) is installed in the PCIe slot of the NetBackup 5000. The RAIDcard connectswith themini serial-attached SCSI (mini SAS) port of the expansionboard through two external mini SAS connectors. This allows the RAID cardsupports up to eight SAS ports.
The RAID card is installed in the PCIe slot that is furthest from the memory. SeeFigure 2-7 on page 23. for the location of the RAID card.
The LSI MegaRAID card is installed in the NetBackup 5000.
Figure 2-8 shows the appearance of the RAID card.
Figure 2-8 Appearance of RAID card
The RAID card has the following features:
■ Flexible SAS/SATA disk array structure
■ Supports RAID 1 and RAID 6 with integrating RAID functions to avoid extraconsumption on the CUP
HardwareRAID card
24
■ Connects the SAS/SATA disks through the advanced serial technology
■ A battery Backup Unit (BBU), which provides power failure protection
Network interface cardThe network interface card (NIC) is installed in the PCIe slot. It connects theNetBackup 5000 to the network switch through Ethernet cables.
The NetBackup 5000 is configured with the dual-port Intel® Pro/1000 PT seriesNIC. It is connected to the GE switch through Ethernet Cables.
The dual-port NIC is a GENIC, and the type of the port is RJ45. The network cableis a category 5 unshielded twisted-pair cable.

The NIC provides the following performance features:
■ High performance and support for 10/100/1000 Mbit/s Ethernet connection
■ Specialized I/O bandwidth for the dense networking applications through theexpandable PCIe port
■ A virtual connection and reduced I/O overhead in the virtual environment,which improves the performance of the entire system
Expansion boardThe expansion board is in the middle of the NetBackup 5000 chassis. It connectsto themainboard through amini SAS cable. It supports expansion to 24 SASportsthat are connected to 24 SATA disks.
Figure 2-10 shows the expansion board of the NetBackup 5000.
Figure 2-10 Expansion board
The expansion board of the NetBackup 5000 has the following advantages:
■ TheNetBackup5000expansionboard requires fewer cables than the traditionalsolution of integrating the servermainboardwith theHBA. That improves thereliability and the stability of the device.

■ Compared with the traditional solution of installing a just a bunch of disks(JBOD)groupoutside the server, theNetBackup5000expansionboard simplifiesthe device installation and maintenance. That improves manageability.
Fan moduleThe fan module provides the heat dissipation function for the NetBackup 5000.
The NetBackup 5000 chassis is configured with six fan modules. The six fanmodules are arranged in two lines, and each line contains three fanmodules. Theyare lettered from a to f, as shown in Figure 2-11. The NetBackup 5000 continuesto function even if a fan module fails.

Power entry modulesThe power entry modules (PEM) provide power for the NetBackup 5000.
The PEM supplies power for the NetBackup 5000 in the ranges of 100 VAC to 127V AC or 200 V AC to 240 V AC. That assumes the ambient temperature rangesfrom 0° C to 49° C.
The rear chassis of the NetBackup 5000 provides two slots for the PEM, and thetwo PEMs are configured in 1+1 redundancy mode.
A single PEM allows the NetBackup 5000 to work normally in maximum powerconsumption mode. When two PEMs are installed, they provide a 1+1load-balancing power system. That ensures the normal running of the systemwhen one PEM is faulty. The PEMs are hot-pluggable.
Figure 2-14 shows the AC PEM of the NetBackup 5000.

Power safety specificationsTheNetBackup 5000 is configuredwith twoPEMs and one filler panel. It supports1+1 redundancy backup. When selecting the installation site of the NetBackup5000, consider the following factors:
■ AC power grounding protection.A grounding cable must be connected to the NetBackup 5000.
■ Overcurrent and overload protection.Circuits and related breakers must have power guarantee and protectionagainst overload.Separate the power supply fromapower supplywithheavypower distributionload. For example, the power supply of the air-conditioner engine, elevatorengine, factory engine. That helps prevent possible damage to the NetBackup5000.

Heat dissipation and air flow requirementsThe NetBackup 5000 uses the heat dissipation mode of “front in and rear out”.The cool air enters from the gaps between the hard disks at the front and passesthrough the backplane into themainboard area. The air that enters the unit coolsdown the mainboard and the expander board and the fans discharge the air. Thebuilt-in fans of the PEMs dissipate the heat of the PEMs.
The entire heat dissipation system consists of six fan modules. When one fanmodule is faulty, the other five fan modules can satisfy the heat dissipationrequirement of the fully runningNetBackup 5000. That assumes an environmenttemperature of 5° C to 35° C.
