VMAX All Flash packaging
VMAX All Flash arrays offer the simplest packaging ever delivered for a platform. The
basic building block is an appliance-based entity called a V-Brick in open system arrays
and a zBrick in mainframe arrays. Each V-Brick or zBrick includes:
l
An engine with two directors (the redundant data storage processing unit)
l
Flash capacity in Drive Array Enclosures (DAEs):
n
VMAX 250F: Two 25-slot DAEs with a minimum base capacity of 13TBu
n
VMAX 450F, VMAX 850F: Two 120-slot DAEs with a minimum base capacity of
53TBu
n
VMAX 950F (open or mixed systems): Two 120-slot DAEs with a minimum base
capacity of 53TBu
n
VMAX 950F (mainframe systems): Two 120-slot DAEs with a minimum base
capacity of 13TBu
l
Multiple software packages are available: F and FX packages for open system
arrays and zF and zFX for mainframe arrays.
Pre-planning tasks
This document uses the term V-Brick for planning purposes. All guidelines that apply
to V-Bricks also apply to zBricks.

NOTICE
Delivery and transportation
Delivery arrangements
Delivery within the United States or Canada is by air-ride truck with custom-designed
shipping material, crate, and pallet. International delivery normally involves air freight.
Unless otherwise instructed, the EMC Traffic Department arranges for delivery
directly to the customer’s computer room. To ensure successful delivery of the
system, EMC has formed partnerships with specially selected moving companies.
These companies have moving professionals trained in the proper handling of large,
sensitive equipment. These companies provide the appropriate personnel, floor
layments, and any ancillary moving equipment required to facilitate delivery. Moving
companies should check general guidelines, weights, and dimensions.
Inform EMC of any labor union-based restrictions or security clearance requirements
prior to delivery.
Pre-delivery considerations
Take into account the following considerations prior to the delivery at your site:
l
Weight capacities of the loading dock, tailgate, and service elevator if delivery is to
a floor other than the receiving floor.
l
Length and thickness of covering required for floor protection.
l
Equipment ramp availability if the receiving floor is not level with computer room
floor.
l
Set up the necessary network and gateway access to accommodate EMC Secure
Remote Support (ESRS) so that it will be available and operable for the installation
date.
Moving up and down inclines
To prevent tipping when moving up and down inclines, the following guidelines are
recommended:
l
When moving cabinets, all doors/drawers should be closed.
l
When moving the cabinet down an incline, the front of the cabinet must go first.
l
When moving the cabinet up an incline, the rear of the bay goes last.
All portions of the bay will clear ramp and threshold slopes up to 1:10 (rise to run
ratio), per Code of Federal Regulations — ADA Standards for Accessible Design, 28
CFR Part 36.

Radio frequency interference
Electro-magnetic fields, which include radio frequencies can interfere with the
operation of electronic equipment. EMC Corporation products have been certified to
withstand radio frequency interference (RFI) in accordance with standard
EN61000-4-3. In Data Centers that employ intentional radiators, such as cell phone
repeaters, the maximum ambient RF field strength should not exceed 3 Volts /meter.
The field measurements should be taken at multiple points in close proximity to EMC
Corporation equipment. It is recommended to consult with an expert prior to installing
any emitting device in the Data Center. In addition, it may be necessary to contract an
environmental consultant to perform the evaluation of RFI field strength and address
the mitigation efforts if high levels of RFI are suspected.
The ambient RFI field strength is inversely proportional to the distance and power
level of the emitting device.
Recommended minimum distance from RF emitting device
The following table provides the recommended minimum distances between EMC
arrays and RFI emitting equipment. Use these guidelines to verify that cell phone
repeaters or other intentional radiator devices are at a safe distance from the EMC
Corporation equipment.

NOTICE
EMC provides the EMC Power Calculator to refine the power and heat figures to more
closely match your array. Contact your EMC Sales Representative or use the EMC
Power Calculator for specific supported configurations. The following table provides
calculations of maximum power and heat dissipation.
Power consumption and heat dissipation details vary based on the number of system
and storage bays. Ensure that the installation site meets these worst case
requirements.

Adaptive cooling
The systems apply adaptive cooling based on customer environments to save energy.
Engines and DAEs access thermal data through components located within their
enclosures. Based on ambient temperature and internal activity, they set the cooling
fan speeds. As the inlet temperatures increase, the adaptive cooling increases the fan
speeds, with the resulting platform power increasing up to the maximum values shown
below. These values, along with the SPS recharge power consumption, contribute to
the maximum system power consumption values over 35°C shown in Table 6 on page
25.

Specifications
Systems are designed for typical hot aisle/cold aisle data center cooling environments
and installation:
l
On raised or nonraised floors.
l
In hot aisle/cold aisle arrangements.
The airflow provides less mixing of hot and cold air, which can result in a higher return
temperature to the computer room air conditioner (CRAC). This promotes better heat
transfer outside the building and achieves higher energy efficiency and lower Power
Usage Effectiveness (PUE). Additional efficiency can be achieved by sequestering the
exhaust air completely and connecting ducts directly to a CRAC unit or to the outside.
Best practice is to place a perforated floor tile in front of each bay to allow adequate
cooling air supply when installing on a raised floor. The following figure shows typical
airflow in a hot aisle/ cold aisle environment.

Air quality requirements
VMAX All Flash arrays 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, ASHRAE TC 9.9 2011.
The arrays are best suited for Class 1A 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. In a data center environment, if
the air conditioning fails and the temperature is lost, a vault may occur to protect
data.
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.
The allowable relative humidity level is 20–80% non condensing, however, the
recommended operating environment range is 40–55%. 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 (RH), EMC recommends using grounding
straps when contacting the equipment to avoid the risk of electrostatic discharge
(ESD), which can harm electronic equipment.
Specifications
As part of an ongoing monitoring process for the corrosiveness of the environment,
EMC recommends placing 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 emplaced.
