There are two SAS controller card options for the Sun SPARC Enterprise T5120 and T5220 servers (both options support RAID). The standard option uses the on-board SAS controller card preinstalled on every server. The second option is a StorageTek SAS RAID Internal Host Bus Adapter (HBA) PCIe card. The internal cabling of your server will be different depending on the SAS controller card option you choose.
Figure 131 HDD Data Cable Routing for SAS RAID Controller Cards in Eight- or Sixteen-Disk Capable Sun SPARC Enterprise T5220 Servers
1 Route both cables between the PCIe slots and FB-DIMMs
2 Route both cables along the power supply midwall
3 Route the 530-4119 cable under the fan midwall and fan boards, to the hard drive backplane
4 Route the 530-3892 cable under the fan midwall and fan boards, to the hard drive backplane
Note - For information about installing the PCIe HBA card, refer to the document, Installing the StorageTek SAS RAID HBA Into the SPARC Enterprise T5120 and T5220 Servers.
