Page 4: Introduction To The Dx Object Storage Cluster Services Node
Chapter 1. Introduction to the DX Object Storage Cluster Services Node 1.1. DX Object Storage Cluster Services Node Overview The DX Storage Cluster Services Node (CSN) is an integrated services node that centralizes installation and configuration of both the network services required to run a DX Storage cluster and the software used to interface with it. -
Page 5: About This Document
1.3. About this Document 1.3.1. Audience This document is intended for people in the following roles. 1. Storage system administrators 2. Network administrators 3. Technical architects Throughout this document, the storage system administrator and network administrator roles will be referred to as the administrator. DX Storage CSN administrators are normally responsible for installation and configuration, license management, monitoring storage system health, software upgrades, backup/recovery, and capacity management. -
Page 6: Installation And Configuration
Chapter 2. Installation and Configuration 2.1. Requirements 2.1.1. Operating System DX Storage CSN has been developed and tested with 64-bit RHEL 5.5; other RHEL versions or Linux distributions are not currently supported. Subsequent installation instructions will assume a pre-installed RHEL Linux environment with either internet connectivity or an alternately configured RHEL yum repository for use in installing required 3rd party packages. -

listening for all communication on the well-known IP addresses for the internal and external network. When a secondary CSN joins the internal network, it registers with the primary CSN via a privileged SSH channel using the primary root password entered during the initial configuration process. This allows the primary to sync needed information to the secondary, specifically the Primary's Backup Manifest UUID. - Page 8 Several prompts will suggest a default value in brackets that can be accepted by simply pressing enter. Is this the Primary CSN (yes/no)? [yes]:: This prompt allows specification of whether or not the CSN is a primary or secondary CSN. The default value is yes. Administrators should take care to ensure that only a single primary CSN is configured on the internal network to prevent conflicts with both DHCP and DX Storage netboot configuration.

. You will be required to authenticate prior to being granted access. The username for the console is 'admin' and the default password is 'dell'. Once authenticated, click on the Licensing link under the Content Storage tab to access the licensing interface. - Page 10 After installation, a license shell is defaulted into the licensing interface. If published as is, this license will provide 0 TB of capacity for storing content. To correctly publish a license the following high-level steps are required: 1. Enter License Contact and Storage Information 2.
- Page 11 2.3.3.1. Contact and Storage Information The license information is displayed once the license is published as part of the license details popup on the DX Storage admin console. To add or update this information, click the 'Edit' button under the License Contact and Storage Information section of the interface and enter the desired company name, address and cluster description information.

to return to the main licensing page. Valid keys will be reflected on the main licensing page after successful entry. 2.3.3.3. Publishing a License Entering hardware and capacity keys in the licensing interface will save the keys to the CSN's local storage. -

that the CSN's local time server is less than 15 layers separated from a reliable source and is therefore reliable enough to serve as an NTP server for the DX Storage on the internal network. 2.5. CSN Hardware Validation With every boot of the CSN after the initial install, the CSN software checks the validity of the host hardware. -
Page 14: Backup Compatibility Across Software Versions
2.6.1. Backup Compatibility Across Software Versions During upgrade, the backup process will not be able to complete and may log errors as a result. After upgrade, previous backup sets may be marked on the Backup and Restore page of the CSN Admin Console as being compatible with a previous software version. -
Page 15: Running And Managing The Csn
Chapter 3. Running and Managing the CSN The CSN Console is the primary administrative interface for the CSN as well as the other services and software installed on the shared server. It allows both basic configuration changes as well as more complex functions like creating manual configuration backups or changing DX Storage software versions. -
Page 16: Updating The Internal Interface
Please reference the 'Configuring the CSN' section of the Installation and Configuration chapter above for full information about each of the parameters. When changing values for any network parameter, the console may return a list of resulting actions that will need to be taken by each of the services and installed software modules. Because the network configuration is central to so many services, it is not unusual for the action list to contain service restarts and possibly a server reboot. -

where 172.20.0.0 is the desired new internal network interface. Best practice is to reboot the DX Storage cluster from the DX Storage admin console and then run the changeinternalnetwork script while the cluster is rebooting so that when the nodes come back online they are assigned a new IP address from the new internal network interface range. -
Page 18: Editing User Access
The username used to access the CSN console is 'admin'. The admin password can be updated from the User Access link under the Cluster Services tab. The default password is 'dell'. Characters are obscured when entered on the page so double entry is required to ensure accuracy. The obscured character count does not necessarily correspond to the number of characters in the password. -
Page 19: Configuration File Backup And Restore
3.5. Configuration File Backup and Restore To help with recovery in the event of a hardware failure, the CSN includes a backup mechanism that backs up its configuration files to DX Storage and then allows restore of those backups at a later date. -
Page 20: Backup Manifest
3.5.1. Backup Manifest A manifest anchor stream is created in the storage cluster with the first backup set and updated with every subsequent backup. The UUID for the manifest is displayed at the top of the backup interface. It will not display until after the 2nd backup has been created. Note Administrators should copy this UUID into a safe location so that in the event of a complete system failure the list of backup sets can be retrieved from the storage cluster. -
Page 21: Automatic Backups
3.5.2. Automatic Backups The backup utility watches a pre-determined list of CSN configuration files for file metadata changes. When a change is detected, the utility waits until the changes stabilize to prevent multiple incremental backups in a short time period and then creates a gzipped tar file with a complete set of all designated configuration files. - Page 22 a backup set from the restored manifest list. The primary's backup manifest must have at least 2 backups in it prior to being used for failover. To assist with this transition, the secondary CSN periodically pulls the primary's Backup Manifest UUID via the privileged SSH channel and stores it in the following location on the secondary: /etc/caringo/csn/primary-manifest.txt.

Page 23: Configuring The Scsp Proxy
3.6. Configuring the SCSP Proxy The SCSP Proxy installation on the CSN allows for clients on the external network, including remote clusters using DX Content Router, to send and receive SCSP requests to and from DX Storage nodes on the internal network. The SCSP Proxy is configured during the network bootstrap process to listen on port 80 of both the external and internal interfaces. - Page 24 The following information is required for all configured remote clusters: Parameter Description Remote Cluster Name The alpha-numeric name for a remote cluster that will be used in requests sent to the proxy. May not contain whitespace. May be the DNS name for the cluster but that is not required.
