cord may be broken, fire may occur, and/or you may be electrically shocked.
Do not install the disk array unit in an area of much moisture or dust. Remove dust
adhering to AC outlets and the plugs of power cords, if any. If dust remains
adhering to an AC outlet and/or plug, fire may occur.
Do not connect the plug of a power cord to an AC outlet with a wet hand. If so, you
may be electrically shocked.
While the disk array unit can accept the power of 100 - 240 VAC (50/60 Hz), the
power cord coming with the disk array unit can only accept 100 – 120 VAC. Use
100 – 120 VAC (50/60 Hz) when the attached power cord is used. Using power of
different voltage may cause electric shock, smoke, and/or fire to occur.
The controller of the disk array unit contains lithium battery. Do not remove the
lithium battery. The lithium battery may explode when it is brought close to fire or
immersed in water. Dispose of the controller according to local ordinance. Contact
your local government for details.
If the disk array unit does not operate normally due to the life of the lithium
batteries, contact your service representative. Do not dis as semble the controller,
or replace or charge battery by yourself.
v
CAUTION
Do not install the disk array unit and the host systems on unstable places. If so,
some substances may be dropped to cause you to be injured.
Do not install the disk array unit and the power cords in an area with direct sunshine
or near an apparatus generating heat such as a heater. If so, a fault may occur.
Further, the coating of the power cord may be melted to cause fire or electric shock
to occur.
Insert the plug of a power cord to an AC outlet securely. Any power cord shall be
routed with sufficient margin to avoid excess force from being given to the plugs of
the power cord or the power cord itself. If a power cord is removed from the AC
outlet during operation, data may be lost and/or a fault may occur.
To prevent electric shocks, connect a power cord to an AC outlet with earth
terminal. Connection of the earth line to a gas tube is extremely dangerous. Never
do it.
Connect or remove a peripheral device from the disk array unit after turning off all
the powers of the disk array unit and peripherals and pulling out the power cords
from the AC outlets. If not, some units may be broken and/or you may be electrically
shocked.
To carry or reinstall the disk array unit, disconnect all cables and power cords
beforehand. If not, some units may be broken, you may be electrically shocked,
and/or a fire may occur.
To install the unit in a rack, observe the following guidelines.
1. TMRA – If installed in a rack, consideration should be given to installing the
equipment in an environment compatible with the TMRA.
2. Reduced Air Flow – Installation in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading – Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit Overloading – Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading the circuits might
have on overcurrent protection and supp l y wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
5. Reliable Earthing – Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g., use of power strips).

While the disk array unit can accept the power of 100 - 240 VAC (50/60 Hz),
the power cord coming with the disk array unit can only accept 100 – 120
VAC. Use 100 – 120 VAC (50/60 Hz) when the attached power cord is
used. Using power of different voltage may cause electric shock, smoke,
and/or fire to occur.
Do not install the disk array unit and the power cords in an area with direct
sunshine or near an apparatus generating heat such as a heater. If so, a
fault may occur. Further, the coating of the power cord may be melted to
cause fire or electric shock to occur.
The disk array unit weighs 34 kg or more. Hold the disk array unit and disk
enclosure firmly with at least three people to carry it. Carrying the devices
only by two or less people may strain their back.
Select the place where the disk array unit can be connected to the AC outlet
by using the attached power cord.
Insert the plug of a power cord into an AC outlet securely. If some clearance
remains between the plug of the power cord and the AC outlet, dust may
enter into the clearance. This then may cause fire to occur.
Provide sufficient margins for the cables connected to the disk array unit so
that legs may not be trapped by the cables. Avoid power plugs and FC
connectors from suffering excess forces.
Do not use cables connected to the disk array unit with them leaving bent. If
so, a fault or fire may occur.
1-4
Use the cables approved by NEC as those connected to the disk array unit
and check the destinations to which the cables are connected. In addition,
always lock power cords and FC cables when they are connected.
Use the power source independent from TV or radio. Otherwise, a noise
may be generated.
To connect a cable to the mating connector, make sure that the connector
of the cable is not damaged and any pins are not bent. Using a cable not
approved by NEC or a damaged cable may cause a fault or fire to occur.
To disconnect a cable from the mating connector, always hold the
connector of the cable. Do not hold the cable itself to disconnect it.
1.4 Notes on Use of Disk Array Unit
Do not let any animal (pet) or children touch the cable connected to the disk
array unit. Pulling the cable may cause the unit to fall down, resulting in
failure of the unit.
Do not enter any liquid such as water into the disk array unit. If so, you may
be electrically shocked or the unit may be defected. If some liquid is entered
into the disk array unit, turn off the power and contact your sales
representative or maintenance engineer. If the disk array unit seems dry,
only a small amount of liquid may remain to cause the unit to be defected.
Do not enter foreign substances such as clip and screw into the disk array
unit through the ventilating holes on the front or rear face. If so, a fault may
occur.

* Ask your sales representative for non-NEC servers (hosts) which are supported and compatible
operating systems.
The storage capacity of the disk array unit can be easily expanded by installing an additional FC disk
drive (option) in the expansion slot of the disk array unit.
An additional FC disk enclosure (option) to enable the expansion of the storage capacity of the disk
array unit is provided for the disk array unit.
The disk array unit supports RAID types 1, 5, 6, 10 and 50. If a fault occurs in a single disk drive (2
disk drives for RAID type 6), the disk array unit can continue the operation without loss of data.
Any defected disk drive can be replaced with a new one without system shutdown. Further, the disk
array unit has the auto repair feature which automatically starts data recovery after the replacement of
the defected disk drive.
If a single disk drive is specified as the spare disk, the data in the defected disk drive can be
immediately recovered in the spare disk. The use of this hot spare feature as well as the auto repair
feature allows the data in the defected disk drive to be automatically recovered in the spare disk as
soon as a disk drive is defected. This improves the system reliability.
The disk array unit has the cache memory data hold function by using the battery backup unit. The
function allows comfortable high-speed data processing to be done under high reliability.
Further, owing to the redundant configuration of the controller, fan, power supply, and battery backup
unit as well as disk drive, high availability is achieved.
See Section 9.2 "Optional Components" for the product names and part numbers of options.
Above features of the disk array unit are effective only for the hardware failure
(e.g., the hard disk is physically damaged or inoperative). The software failure
(e.g., the data is lost or rewritten due to program excursion) is not covered by
these features. When the software failure would occur, the system could seriously
be damaged. To minimize the damage, be sure to back up the data periodically.

2.1 Hot Spare Feature
Spare disks can be installed in the disk array unit. If a disk drive is defected, the data in the defective
disk drive is recovered in the spare disk. After the data recovery, the disk drive operates normally if
another disk drive is defected.
A defective disk drive can be replaced without turning off the power of the disk array unit.
With the shipping default, if the disk drive defected during the operation by using the spare disk is
replaced with a normal disk drive, the replaced disk drive works as a spare disk.
The data can also be recovered in another other disk enclosure.

Do not move any of the factory-installed disk drives into another slot.
The spare disk can operate only when it has a capacity and a revolution
equal to the defected disk drive.
If disk drives having different capacities and/or revolutions coexist, spare
disks of the different capacities and/or revolutions are defined to manage the
disk drives clearly.
Up to 32 spare disks may be installed in the entire disk array unit.
2-3
2.2 Write Cache Feature
For RAID type 5, 6, or 50, the performance of the disk array unit may be decreased during writing of a
small amount of data. It is because the previous data and parity data must be read to recalculate the
parity.
The disk array unit is equipped with cache memory. When write data is stored in the cache memory,
the disk array unit terminates the command processing and then writes the data to disk drive for
improving the performance.
The cache memory is backed up with the battery backup unit. To increase data security,
an uninterruptible power supply (UPS) should also be used.
In general, if the power is shut down before the data saved in the cache memory is written to disk
drive, the data in the cache memory will be lost. To prevent this, the disk array unit provides the
battery backup by battery backup unit installed in the power supply to retain data in the cache memory.
The backup time using the battery backup unit is res tri cted as follow s :
The backup time of battery backup unit depends on the number of battery backup units installed. The
following table shows the backup time when the battery backup units are installed and they are fully
charged.

* If the discharging (power-off) time exceeds 16 hours in daily use, the battery back units
need to be replaced at a cost before they reach the service life of 5 years. Ask your
NEC sales representative for the relation between the operation mode and the life of a
battery backup unit.
The following conditions are imposed to make the write cache feature effective:
The disk array unit is operating normally with the following components being installed:
– 2 controllers (or 1 controller if you have made the setting to enable Write Cache from the
maintenance PC)
– 1 or more power supplies
– 1 or more battery backup units installed in the power supply or power supplies above
(BBU0 for PS0 and BBU1 for PS1)
The battery backup units are fully charged.
If any of the conditions is not satisfied, the write cache feature does not work sufficiently.
The batteries installed in the battery backup unit are fully charged for about eight hours.
