Overview

OverviewAn EMC® VPLEX™ cluster requires a properly equipped computer room with controlled temperature and humidity, proper airflow and ventilation, proper power and grounding, system cable routing facilities, and fire equipment.

To verify that the computer room meets the requirements for VPLEX, confirm that:

◆ Any customer concerns have been addressed through planning sessions between EMC and the customer.

◆ The site meets the requirements described in this document.

◆ The site contains LAN connections for remote service and system operation.

As a reference, you should download and install the VPLEX Procedure Generator from Powerlink. The procedure generator provides documentation that is customized for specific procedures, such as hardware upgrades and replacement.

Note: VS1 systems are available as factory-racked only. However, VS2 can be ordered factory-racked or field-rackable. The following sections describe the requirements for factory-racked and field-rackable systems.

Preparing the site to install a VPLEX cluster installed in an EMC cabinet

Cabinet clearance You must provide adequate clearance at the rear to service and cool the VPLEX components. Figure 1 shows the required clearance for the 40 U EMC cabinet.

Confirm that the doorways and elevators are wide and tall enough to accommodate the shipping pallet and cabinet. Figure 2 shows the dimensions of the boxed EMC cabinet.

Cable routing EMC recommends installing the equipment into a room with a raised floor, for accommodation of the cabling under the floor. If the customer plans to route the cables out the top of the cabinet instead, EMC recommends adding the optional top-route kit to the VPLEX order.

If you are installing the cabinet onto a raised floor, cut a cable-access hole in one tile as shown in Figure 3 on page 4.

Figure 3 Floor tile cutout

Floor load Table 1 shows the approximate weight of each VPLEX cluster configuration.

A VPLEX cabinet can be installed in a raised or nonraised floor environment. The raised floor environment is the preferred installation environment.

If the cabinet is installed in a raised floor environment, the customer must ensure that the raised floor is capable of supporting the system weight. EMC recommends the use of 24 X 24 in. heavy-duty, concrete-filled steel floor tiles. If a different size or type of tile is used, the customer must ensure that the tiles have a load rating that is sufficient for supporting the system weight.

To ensure proper physical support of the cabinet, the following requirements, which are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles, must be met:

◆ Floor must be level.

◆ Floor tiles and stringers must be rated to withstand concentrated loads of two casters, each load weighing up to 600 lb (272.2 kg).

◆ Floor tiles and stringers must be rated for a minimum static ultimate load of at least 1800 lb (816.5 kg) per tile.

◆ Floor tiles must be rated for a minimum of 600 lb (272.2 kg) rolling load.

Quad-engine 1664 lb (754.8 kg) 1418 lb (643.2 kg)



◆ Floor tile deflection must be minimized with additional pedestal mounts.

◆ Do not position the cabinet with more than two casters on a single floor tile.

Note: Cutting tiles per specifications as shown in Figure 3 on page 4 ensures the proper caster placement.

◆ Use or create no more than one floor tile cutout that is no more than 8 in. (20.3 cm) wide by 6 in. (15.3) deep in each 24 x 24 in. (61 x 61 cm) floor tile.

◆ Floor tile cutouts will weaken the tile. Therefore, at least one additional pedestal mount adjacent to the cutout of a tile is recommended. The number and placement of additional pedestal mounts relative to a cutout should be in accordance with the tile manufacturer’s recommendations.

◆ Care should be taken when positioning the bays to make sure that a caster is not moved into a cutout.

◆ Ensure that the weight of any other objects in the data center does not compromise the structural integrity of the raised floor and/or the subfloor (nonraised floor) of the data center.

The EMC cabinet includes four caster wheels, shown in Figure 4 on page 6. The front wheels are fixed, and the two rear casters swivel through a 1.75-inch diameter. The swivel position of the caster wheels determines the load-bearing points on the site floor, but does not affect the cabinet footprint. Once you have positioned, leveled, and stabilized the cabinet, the four leveling feet determine the final load-bearing points.

Stabilizer brackets If you intend to secure the optional stabilizer brackets to the site floor, prepare the location for the mounting bolts. (The additional brackets help to prevent the cabinet from tipping while cantilevered levels are being serviced, or from rolling during minor seismic events.) The brackets provide three levels of protection for stabilizing the unit:

◆ Anti-tip bracket (Figure 5) — Provides an extra measure of anti-tip security. You can use one or two anti-tip brackets.

Figure 5 Anti-tip bracket

◆ Anti-move bracket (Figure 6) — Fastens the unit to the floor.

Power requirements

Power cables Power cables and connectors depend on the type ordered with the VPLEX equipment, and must match the supply receptacles at the site. Table 2 shows the connector types.

Each AC circuit requires a source connection that can support a minimum of 4800 VA of single phase, 200–240 VAC input power. For high availability, the left and right sides of the cabinet must receive power from separate branch feed circuits.

Note: Each pair of power distribution panels (PDPs) in the cabinet can support a maximum of 24 amps AC current draw from devices connected to its power distribution units (PDUs). All VPLEX configurations draw less than 24 amps, and require only two discrete 240 VAC power sources.

Note: “Air quality requirements” on page 16 provides detailed air quality information.

Shipping and storage requirementsTable 7 shows the shipping and storing requirements for VPLEX equipment.

Air quality requirementsEMC products are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b.

VPLEX is best suited for Class 1 datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission-critical equipment and are typically fault-tolerant, including the air conditioners.

The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the data center should be filtered with a MERV 11 filter or better. The air within the data center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.

For data centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the data center should be minimized. It is also recommended that the data center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.

For facilities below 40% relative humidity, EMC recommends using grounding straps when contacting the equipment to avoid the risk of electrostatic discharge (ESD), which can harm electronic equipment.

As part of an ongoing monitoring process for the corrosiveness of the environment, it is recommended to place copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity), in airstreams representative of those in the data

center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put in place.
