Dell DX Object Storage – File Gateway Architectural ReferencePage 5Failover ConfigurationThe failover configuration allows CFS servers to be deployed in pairs so that if one server fails, theshare can be recovered by the other CFS server to minimize recovery time. In this configuration, theCFS servers utilize iSCSI storage to store spooled data.HardwareThis configuration consists of the following hardware: (2) PowerEdge R410 serverso Chassis: Up to four Hot-Plug Hard Drives, LCD diagnosticso Processor(s): 2 x E5620, 2.4GHz 12M Cache, Turbo, HT, 1066MHz Max Memo Memory Configuration: 24GB Memory (6x4GB), 1066MHz Dual Ranked RDIMMs forProcessors, Optimizedo HDD Configuration: RAID 1 configuration; internal drives in RAID 1 for OS andapplication; spooled data and namespace stored on iSCSIo Primary Controller: SAS 6.iR SAS internal RAID adapter for Hot Plug Configuration, PCI-Expresso Hard Drives: (2) 500GB 7.2K RPM Near-Line SAS 3.5in HDDo PSU: 500Watt Redundant power supplieso Embedded Management: iDRAC6 Enterpriseo Network Adapter: Broadcom NetXtreme II 5709 Gigabit NIC w/TOE & iSOE, Quad Port,Copper, PCIe-4o DVD-ROM Driveo Operating System: RHEL 6 X64 Basic with 3 Year Subscription (1) iSCSI Storage: MD3200io Controllers: Single or Dual controller optionso Hard Drives: Up to 12 3.5in HDD with the following HDD options- 500GB near-line SAS 6GB, 7.2K, 3.5in HDD- 300GB SAS 6GB, 15K, 3.5in HDD- 450GB SAS 6GB, 15K, 3.5in HDD- 600GB SAS 6GB, 15K, 3.5in HDD- 2TB near-line SAS 6GB, 7.2K, 3.5in HDDo HDD Configuration: RAID5
