DX Object Storage Platform Overview Network Topologies The Dell DX Object Storage Platform network consists of one or more DX Storage Clusters connected by DX Content Router services. There are many possible network topologies depending on the storage network goals. All networks share the following features: •...
Advanced Administration Guide at support.dell.com/manuals. Local Cluster Configuration A basic Dell DX Storage Cluster consists of at least one DX Cluster Services Node and at least two DX Storage Nodes, along with the necessary Ethernet infrastructure to connect them. See Figure 2-1.

DX Storage Nodes. A single name allows communication with the DX Storage Nodes using one domain name. DNS automatically rotates addressing through the storage nodes. For more information, see the DX Object Storage Application Guide at support.dell.com/manuals. DX Object Storage Platform Overview...
Communicating Directly With a Remote Cluster Applications may communicate with a remote DX Storage Cluster during local-cluster disaster recovery. For an application to communicate to a remote DX Storage Cluster, the DX Cluster Services Node on the remote public network must be addressed. A proxy server on the DX Cluster Services Node (on the local cluster) accepts HTTP requests from the application and forwards them to a DX Storage Node in the DX Storage Cluster.
Installing the Initial Cluster or Redundant Cluster Services Node The Dell DX Object Storage Platform consists of at least one DX Cluster Services Node and two DX Storage Nodes. Installation of the initial cluster or additional cluster services nodes require deployment services from Dell.
Adding Additional DX Storage Nodes Before setting up the DX Storage Node, locate the Getting Started Guide for your Dell DX6axyS system. Unpack and set up the DX platform hardware. To set up the DX Storage Node hardware: 1 Rack and cable the DX6axyS system...
DX6axyS system in the rack. Cabling the Appliance Locate the Dell DX6axyS Getting Started Guide that shipped with your system and follow the instructions to attach the power cables and network cables to the DX6axyS system.
To add additional network adapters: 1 Turn off the DX Storage Node. 2 Follow the steps to add a network adapter in the Dell DX6axyS system Hardware Owner's Manual. 3 Connect the Ethernet ports to the private network.
Adding Cluster File Server Nodes Installation of a DX CFS node requires deployment services from Dell. For information about setting up the hardware, see the Hardware Owner’s Manual for your system at support.dell.com/manuals. Setting Up the DX Object Storage Platform...

It is recommended that you download the updates to ensure that the cluster runs optimally. See the Dell DX Object Storage Platform Interoperability Guide at support.dell.com/manuals to determine the minimum software versions supported.
Checking Software Version Compatibility The versions of the software and hardware components installed in the cluster are checked by the Dell DX Compatibility Manager which is installed on the DX Cluster Services Nodes. The Compatibility Manager collects information about the current BIOS, firmware, drivers, and software versions in your cluster.
Troubleshooting the Compatibility Manager If you experience problems with Compatibility Manager, verify that the latest version is installed. Compatibility Manager can be downloaded from support.dell.com. Run the following commands to determine the current version of: • The package name— #rpm -q -a|grep dellacm •...

If a single disk failure occurs, replace the failed hard drive. For more information, see Hardware Owner's Manual for the affected system at support.dell.com/manuals. After the hard drive is replaced, it is automatically assigned by the RAID controller and rebuilt into the disk group.
RAID disk groups and virtual disks. The BIOS Configuration Utility is independent of the operating system and is available during system startup. See the Dell PowerEdge RAID Controller (PERC) H700 and H800 User's Guide at support.dell.com/manuals for more information about the BIOS Configuration Utility and virtual disk management.
Use the Unified Server Configurator - LifeCycle Controller Enabled (USC- LCE) utility on the system to recover the operating system. For specific instructions, see "Deploying the Operating System using the OS Deployment Wizard" in the Dell Unified Server Configurator - LifeCycle Enabled User Guide at support.dell.com/manuals. CAUTION: Reinstalling the operating system on existing disk drives erases all installed applications and data.
