Rack and cable (power and network) the DX Object Cluster and the CFS Server(s). Set up the DX Object Cluster. Set up the CFS Server.
Dell DX Object Storage – File Gateway Deployment Guide Failover, Active Directory Member, External Spooler (DX Cluster + 2 CFS Systems + MD3200i, member of Active Directory) Complete the Site Survey Technical review. Order placement and delivery. Rack and cable (power and network) the DX Object Cluster and the CFS Server(s). Set up the DX Object Cluster. Set up the CFS Server. Configure SMB/CIFS gateway protocols for Active Directory Member Server.
Dell DX Object Storage – File Gateway Deployment Guide Shared Storage System – Shared storage is a cache where files are stored before they get written to the DX Object Storage and also where they can be accessed on subsequent reads, if locally available. A separate shared storage system, such as the MD3200i is required for failover solutions.
Dell DX Object Storage – File Gateway Deployment Guide Single Server CFS Configuration Dual Port NIC 0 1 CIFS/NFS Network Quad Port, TOE/iSOE NIC 2 3 4 5 DX Cluster Network Failover Configuration The failover configuration allows DX6000G CFS servers to be deployed in pairs so that if one server fails, the share can be recovered by the other CFS to minimize recovery time. In this configuration, the CFS servers utilize iSCSI storage to store spooled data.
Dell DX Object Storage – File Gateway Deployment Guide that have suitable competence may prefer configuration and management of link aggregation control protocol in place of adaptive load balancing. The preferred failover network configuration is identical to a single-server CFS configuration (above), except that iSCSI traffic shares the four NIC ports on the private DX Storage network.
Dell DX Object Storage – File Gateway Deployment Guide Software The following briefly describes the standard software components for DX Object Storage Gateway solutions. Red Hat Enterprise Linux – This is the operating system residing on the Cluster Services Node and the CFS Server. Different versions may run on the DX6000G CFS and the CSN. See the interoperability matrix for information about versions.
Dell DX Object Storage – File Gateway Deployment Guide How it all works together The data flow in a DX Object Storage File Gateway depends on the type of configuration. The following examples showa DX Object Storage cluster with a single-server gateway, and a DX Object Storage cluster with a failover gateway. DX Object Storage File Gateway (single-server) In a DX Object Storage File Gateway, data objects are written to a DX6000G CFS server before being written to a Storage Node.
Dell DX Object Storage – File Gateway Deployment Guide DX Object Storage File Gateway (Failover) A failover configuration (see Figure 2) provides two DX6000G CFS servers and a separate dedicated spool/cache.
