LaCie 12big Rack Fibre and expansion Disk Rules and Configuration/Setup and CablingQuick Install Guide page 7Disk Rules and4.ConfigurationDisk Slot Arrangement4.1.cauTion: All disk slots must have either a Disk Carrier orDummy Carrier module installed. No slot should be left empty.Disk Confi guration Rules4.2.The 12big rack fibre and expansion enclosure systems supporttwo different types of disks: SATA and SAS. In order to allowoptimal configurations to be built, the following rules shouldbe observed.• Different disk types cannot be mixed in the same column.• SATA disks must either have all Active-Passive or allActive-Active MUX Transition cards. They cannot be mixedin an array.• To achieve optimum performance, slots should be popu-lated in the following sequence, if all slots are not beingpopulated (see Figure 6):1 - Column 2 (Disks 2, 6, & 10)✦2 - Column 3 (Disks 3, 7, & 11)✦3 - Column 1 (Disks 1, 5, & 9)✦4 - Column 4 (Disks 4, 8, & 12)✦• If it is necessary to install a different type of drive, install thenew drive in a different column (see figure 6). All drives in thecolumn should be the same drive type.Figure 5: Slot Number Identifi cationSetup and Cabling5.SFP Installation5.1.Remove the dust cover from each of the SFP cages and1.SFP Transceivers to be populated.Insert the SFP Transceiver into the SFP cage and push2.to seat it. Ensure the ejector is positioned to its storedlocation.Connect the fibre channel data cables as described in3.the next section.Ethernet Connection (Embedded5.2.StorView)The controller is connected to the network for out-of-bandmanagement and monitoring via the RJ45 10/100 BaseT Eth-ernet port, using the embedded StorView Management mod-ule and software.Ensure that the host computer is connected either directly to orvia a switched LAN to the Ethernet port on the RAID Controllerusing a shielded Cat 5 cable.iMPoRTanT: Only shielded Cat 5 (or better) cables should beused for connection to the Ethernet port for EMC conformance.Example of Ejector StoredFigure 7: Installing the SFP ModulesFigure 6: Drive Population Order and Sample Type Loading
