PS Series 3000 QuickStartStep 1. Set Up the Array HardwareB. Mount Array in a Stable RackA PS Series array must be mounted in a two-pole or four-pole 19” rack.Instructions for rack assembly and mounting an array are included with thetwo-pole assembly kit and the four-pole assembly kit in the array shipping box.When mounting an array in a rack, you must meet the following recommendationsand requirements: Be sure there is sufficient space for air flow in front of and behind the array. It is recommended that you attach the rack to the floor for added stability. Be sure to support the array until it is completely mounted in the rack. The location of the array must be properly vented and must meet theenvironmental, power, and physical requirements described in thefollowing table.PS Series Storage Array RequirementsComponentRequirementWeight of fully-loaded array80 pounds or 36.36 kilogramsOperating temperature41 to 104 degrees F / 5 to 40 degrees CStorage temperature-22 to 140 degrees F / -30 to 60 degrees CMaximum altitude10,000 feetOperational relative humidity8 to 90% non-condensingThermal output of fully-loaded array2200 BTU/hour, 660 wattsShock30 G for 2 msVibration.1 G @ 10 to 100 hertzInput voltage90 to 264 VAC (auto-sensing)Input current5.5 amperes (maximum, single power supply)@ 120 voltsInput frequency50 to 60 hertzInput power660 VAPower suppliesDual, 450 watts DC outputHeight/Width/Depth5.25” x 17 5/8” x 22.5”13.33 cm x 44.77 cm x 56.25 cm6

PS Series 3000 QuickStartStep 1. Set Up the Array HardwareC. Connect Power Cables for GroundingA PS Series array includes two power supply/cooling modules. It is recommendedthat you connect both power supplies to different sources of power, preferably onseparate circuits for increased availability.For a highly-available power configuration, connect one power supply to anuninterruptible power supply (UPS) system, and connect the other power supplyto a different source of power. See the table PS Series Storage Array Requirementson page 6 for information about voltage requirements.Notes: Do not turn on power to the array. At this time, the power cables are onlyfor grounding purposes.If your PS Series array was shipped with power cables, use these cables tomeet safety requirements.To connect power cables to an array, refer to the figure shown next. Be sure to usethe cable strain relief when securing the power cable in the array.Connecting Power Cables8

PS Series 3000 QuickStartStep 1. Set Up the Array HardwareD. Connect Array to a Network SwitchA PS Series array includes one or two control modules. Only one control moduleis active (serving network traffic) at one time. The secondary (redundant) controlmodule mirrors cache data from the active control module. If the active controlmodule fails, the secondary will take over network operations.Each control module has three Ethernet network interface ports, labeled PORT 0,PORT 1, and PORT 2, for up to three active connections to the network.In addition to the requirements and recommendations described in the followingtables, all the usual rules for proper network configuration apply to the groupmembers. General network configuration is beyond the scope of this document.Network RequirementsRequirementDescriptionAn array must have at least one functioning network interfaceOne or morenetwork connections connected to a network (through a network switch, if possible).When you configure the array, as described later in thisQuickStart, you assign an IP address and netmask to this interface.In a dual control module array, to ensure network availabilityregardless of which control module is active, connect a cable tothe network interface port on each control module.Correct networkcablesUse Category 5E or Category 6 cables with RJ45 connectors. Youcan also use Category 5 cables if they adhere to the TIA/EIATSB95 standard.Network RecommendationsRecommendation DescriptionSwitched GigabitEthernet networkConnect arrays and hosts to a switched network and ensure that allnetwork connections between hosts and arrays are GigabitEthernet. An array can operate at 10 and 100 Mbits, butperformance will be significantly degraded.Multiple networkconnectionsFor increased bandwidth and availability, connect multiplenetwork interfaces to the network (and different switches, ifpossible). Connect interfaces in the following order: PORT 0,PORT 1, and PORT 2.After the initial setup, use the Group Manager GUI or CLI toassign an IP address and netmask to each additional interface.9

PS Series 3000 QuickStartStep 1. Set Up the Array HardwareNetwork Recommendations (Continued)Recommendation DescriptionAccess to the groupIP addressIn a multi-subnet group, each configured network interface shouldhave access to the subnet on which the group IP address resides.Redundant networkpathsUsing a multipathing solution helps to ensure that no single pointof failure exists between hosts and arrays.For replication, areliable, adequatelysized network linkFor effective and predictable replication, be sure that the networklink between the primary and secondary groups is reliable andprovides sufficient bandwidth for copying data.No STPfunctionality onswitch ports thatconnect end nodesDo not use Spanning-Tree (STP) on switch ports that connect endnodes (iSCSI initiators or storage array network interfaces).However, if you want to use STP or RSTP (preferable to STP),you should enable the port settings available on some switchesthat let the port immediately transition into STP forwarding stateupon link up. This functionality can reduce network interruptionsthat occur when devices restart, and should only be enabled onswitch ports that connect end nodes.Note: The use of Spanning-Tree for a single-cable connectionbetween switches is encouraged, as is the use of trunkingfor multi-cable connections between switches.Flow ControlEnable Flow Control on each switch port and NIC that handlesenabled on switches iSCSI traffic. PS Series arrays will correctly respond to Flowand NICsControl.Unicast stormcontrol disabled onswitchesDisable unicast storm control on each switch that handles iSCSItraffic, if the switch provides this feature. However, the use ofbroadcast and multicast storm control is encouraged on switches.Jumbo FramesEnable Jumbo Frames on each switch and NIC that handles iSCSIenabled on switches traffic to obtain any performance benefit and ensure consistentand NICsbehavior.VLANs10Configure switches to use VLANs in order to separate iSCSI SANtraffic from other network traffic.

PS Series 3000 QuickStartStep 1. Set Up the Array HardwareThe minimum network configuration for a single control module array is onenetwork connection to PORT 0. The minimum network configuration for a dualcontrol module array is one network connection to PORT 0 on each controlmodule, as shown in the figure Minimum Dual Control Module NetworkConfiguration. This configuration protects against control module failure.Minimum Dual Control Module Network ConfigurationFor maximum network bandwidth and availability, connect cables to all networkports and distribute the connections across multiple network switches, as shown inthe figure High Performance, High-Availability Network Configuration.High Performance, High-Availability Network Configuration11

PS Series 3000 QuickStartStep 1. Set Up the Array HardwareF. Connect Array to a Console TerminalEstablish a serial connection between the array and a console terminal (or acomputer running a terminal emulator) to run the setup utility, which enablesyou to configure the array and add it to a group. After setting up the array, theserial connection is not needed, but you should keep the serial cable. You can usea serial connection if there is no network access to the group or array.Note: If you have a Microsoft Windows system, you can use the EqualLogicRemote Setup Wizard to configure an array and create a group instead ofusing the setup utility. The wizard does not require the serial cable.The serial connection must have the following characteristics: 9600 baudOne STOP bitNo parity8 data bitsNo hardware flow controlTo create a serial connection, obtain the null modem cable that shipped with thearray and refer to the next figure. The serial cable must always be connected toSerial Port 0 on the active control module (ACT LED will be green).Connecting the Serial Cable15
