16 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment Enviromental Requirements Table 2.4 Environmental Requirements +15 C to +32 C (59 F to 89.6 F) site temperature 40% to 55% relative humidity 0 to 2439 meters (0 to 8,000 feet) above sea level operating altitude Air Quality Requirements EMC 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. The data center should maintain a cleanliness level as identified in ISO , 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 to 80% non condensing, however, the recommended operating environment range is 40 to 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, it is recommended to use 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 , 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. Confirming Site Requirements 14

17 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment This EMC cabinet ventilates from front to back; you must provide adequate clearance to service and cool the system. Depending on component-specific connections within the cabinet, the available power cord length may be somewhat shorter than the 15-foot standard. Figure 2.1 Access and Ventilation Requirements Optional Securing Brackets If you intend to secure the optional stabilizer brackets to your site floor, prepare the location for the mounting bolts. The additional brackets help to prevent the cabinet from tipping while you service cantilevered levels, or from rolling during minor seismic events. The brackets provide three levels of protection for stabilizing the unit. Anti-Tip Bracket Anti-Move Bracket Seismic Restraint Bracket Optional Securing Brackets 15

18 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment Anti-Tip Bracket Use this bracket to provide an extra measure of anti-tip security. One or two kits may be used. For cabinets with components that slide, EMC recommends that you use two kits. Figure 2.2 Anti-Tip Bracket Placement Anti-Move Bracket Use this bracket to permanently fasten the unit to the floor. Figure 2.3 Anti-Move Bracket Placement Optional Securing Brackets 16

19 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment Seismic Restraint Bracket Use this bracket to provide the highest protection from moving or tipping. Figure 2.4 Seismic Restraint Bracket Placement Optional Securing Brackets 17

20 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment Cabinet Positioning The cabinet bottom includes four caster wheels. The front wheels are fixed; the two rear casters swivel in a 1.75-inch diameter. Swivel position of the caster wheels will determine the load-bearing points on your 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 on your site floor. Figure 2.5 Cabinet Positioning When the cabinet is centered over two typical 24 in. (60.96 cm) by 24 in. (60.96 cm) floor tiles: Cutouts should be 8 in. (20.32 cm) by 6 in. (15.24 cm). Cutouts should be centered on the tiles, 9 in. (22.86 cm) from the front and rear and 8 in. (20.32 cm) from sides. Cabinet Positioning 18

21 Greenplum DCA Site Preparation Guide Chapter 2: Preparing the Data Center Environment Package Dimensions and Clearance Make certain your doorways and elevators are wide enough and tall enough to accommodate the shipping pallet and cabinet. Use a mechanical lift or pallet jack to position the packaged cabinet in its final location. Figure 2.6 Door Clearance Leave approximately 2.43 meters (8 feet) of clearance at the back of the cabinet to unload the unit and roll it off the pallet. Figure 2.7 Unloading Clearance Package Dimensions and Clearance 19

22 Greenplum DCA Site Preparation Guide Chapter 3: Gathering Site-Specific Information 3. Gathering Site-Specific Information In order to complete an installation of an EMC Greenplum DCA, the following information should be gathered from the customer s network and database personnel: Table 3.1 Site-Specific Information Information External IP and hostname of the primary master External IP and hostname of the standby master Netmask Gateway NTP server IP DNS name server IP idrac password root password gpadmin password System locale System timezone Description This is the IP address and hostname that the customer will use to connect to the primary master host from their public LAN. The master hostname is also used for client connections to Greenplum Database. This is the IP address and hostname that the customer will use to connect to the standby master host from their public LAN. Netmask of the customer s network. Default gateway of the customer s network and the IP address and interface name of the router. The IP address or hostname of the customer s preferred NTP (Network Time Protocol) server. The IP address of the customer s DNS name server. This is the password used for remote access to the master, standby master and segment hosts using the integrated Dell Remote Access Controller (idrac) interface. The default idrac password is calvin. Customer supplied root password for the master, standby master and segment hosts. The default root password is changeme. Customer supplied Greenplum Database superuser password. The default gpadmin password is changeme. The preferred locale to be used on the master, standby master and segment hosts. en_us.utf-8 is the default locale for the Greenplum DCA (U.S. English and Unicode character set encoding). A locale identifier consists of a language identifier and a region identifier, and optionally a character set encoding. For example, sv_se is Swedish as spoken in Sweden, en_us is U.S. English, and fr_ca is French Canadian. If more than one character set encoding can be useful for a locale, then the specifications look like this: en_us.utf-8 (locale specification and character set encoding). The local timezone to be used on the master, standby master and segment hosts. The default timezone is PST. 20

23 Greenplum DCA Site Preparation Guide Chapter 3: Gathering Site-Specific Information Table 3.1 Site-Specific Information Information Database character set encoding Software Tools Hardware Tools Description UNICODE (UTF-8) is the default character set encoding for Greenplum Database (server-side encoding). This is usually the best choice, as it allows the customer to store all possible Unicode characters from any language, but if all data you are storing is from a single language (now and in the future), it does entail a slight storage space penalty compared to an encoding specific to that language. If the space savings is key, the customer should consider Latin-1, Latin-9, or WIN1252 for US or Western European installations, since those encodings use a single byte per character. Likewise in Thailand you might consider WIN874 to store Thai, since it uses a single byte per character. However, keep in mind that this prevents storing any data outside those character sets. Even in the US or Western Europe, customers might find that some of their data is Latin-1, while some is Latin-9 or Win1252, so any choice of single-byte encoding will not accommodate all of their data needs. See the Greenplum Database Administrator Guide for a list of all supported character set encodings. Connection to the DCA for setup and management requires an SSH utility. EMC recommends Putty or Cygwin. The following hardware tools will be required during installation of the DCA: Utility Knife 9/16 Socket Wrench ESD (electro-static discharge) kit Power Connection for Service Laptop Dial-home Connectivity Power for external devices should not be drawn from the DCA cabinet. A power connection is required for the EMC personnel service laptop. The connection should be a standard AC V~1.5A, 50-60hz outlet. The DCA supports dial-home for event notification to EMC Global Services support center. Communication from the DCA to EMC is done via FTPS. Firewall access should be setup to allow FTPS traffic from the DCA s external IP address to the following EMC addresses: corpusfep3.emc.com corpusfep4.emc.com 21
