Overview 1 This solution is a storage building block based on PowerEdge servers and Dell Storage enclosures, which enables deployment of an ultra-dense storage platform paired with Scality software, for object-based storage or file-based storage on the petabyte scale. Supported services include object level protocols: Scality REST; RS2/Amazon; Openstack Swift; and Cloud Data Management Interface (CDMI).
Setting up the Dell Storage Designed for Scality RING solution 2 Overview Any Dell Storage Solution Designed for Scality RING can support both file and object protocols simultaneously. The two options, File Service and Object Storage solutions, are provided based on best practices for an initial configuration. Customers can choose to add dedicated Connector servers at any time, which is most common with file based protocols.
A minimum of six Dell SD7000-S Single Node or three Dell SD7000-S Dual Node servers are required to form a storage RING consisting of six Physical Servers. Additional Dell SD7000-S servers can be added in any increment. Supervisor In both solutions, a Dell SD630-S server functions as a central management console that monitors and configures the Scality RING solution, referred to as the Supervisor.
File Services solution 3 In the File Services solution, an additional Dell SD630-S server is required for each Connector. As shown in the following figures, a Dell SD630-S server is configured as a Connector.
Figure 2.
Object Storage solution 4 The Object Storage solution differs from the File Server solution. In this solution, the Dell SD7000-S Physical Servers not only host storage nodes, but each Physical Server can optionally host a Connector. Each Connector provides an interface for disk storage and outside applications, receive requests, and dispatch objects.

Installation prerequisites 5 The following sections outline the installation prerequisites. Rack space Use the following images to configure the rack. Figure 5. Rack space—Single Node 1. Switches for management, application, and storage networks 2. Dell SD630-S (Supervisor) 3. One or more Dell SD630-S (Connector– file server only) 4.

Minimum three Dell SD7000-S Dual Node Dell Storage Designed for Scality RING requires racks with a minimum depth of 1200 mm (48 inches). Ensure that there is enough contiguous rack space in the rack for your solution, as shown in the following table.

File Server (with one Connector) Object Storage (with one Connector) Server management Either 10 Either 8 Storage network Static 16 Static 14 Application network Static 2 Static 2 NOTE: The Dell SD7000-S (Single or Dual Node) server requires two management IP addresses for each Physical Server. The iDRAC port for each Physical Server provides concurrent access to iDRAC and the OS.
Storage network The Dell Storage Designed for Scality RING solution requires a switch for the storage network. The selection depends on the NDCs selected for the Dell SD7000-S and Dell SD630-S servers. Dell recommends having two bonded network connections from each server to the application network routed through two separate, redundant switches. Installing hardware Installation summary About this task To install the Dell Storage for Scality RING solution, complete the following steps: Steps 1.
NOTE: Sled B is blank in single node configurations. For example, if you have a configuration that contains 20 HDDs and two SSDs, install the HDDs in drive slots 0 through 9 in Expander A and Expander B, and install the SSDs in slot 44 for Expander A and Expander B. Install the drive blanks in slots 10 through 43. Figure 7.

Carrier Handle Installing the hard drives into the Dell SD7000-S Dual Node server Install drives into the open slots in each Dell SD7000-S server as shown in the figures here. The Physical Server located in the lower sled A connects to the 45 slots in dark grey and the Physical Server located in upper sled B connects to the 45 slots shown in light grey.

Installing the Dell SD630-S servers into the rack space NOTE: For weight stability, always load the rack by using a bottom-up approach. Before you install the Dell SD630-S, you must first install the Dell DS7000-S near the bottom of the rack. Cabling the network connections This section shows how to connect the Dell SD630-S server or a Dell SD7000-S server to a network. NOTE: Port 0 refers to left port and Port 1 refers to the right port as viewed from the back.

Figure 13. Connecting a Dell SD7000-S Dual Node server to network (Physical Servers) Network connections for the Dell SD7000-S Dual Node server are shown for the Sled B (top Physical Server). Configure Sled A (lower Physical Server) identically to the Sled B. NOTE: The Dell SD7000-S Single Node server consists only Sled A. A dummy sled is installed in place of Sled B. Table 8.
Turning on the servers Press the power button on the server being configured. The buttons are on the front of the Dell SD630-S and Dell SD7000-S servers. The power LEDs illuminate when the system is turned on.
Installing the OS 6 The operating system (OS) installation steps vary depending on the particular OS being installed. To install your OS, see the OS vendor for instructions. OS installation summary About this task To install the OS, complete the following steps: Steps 1. Attach monitor, keyboard, and mouse to the server.
NOTE: This procedure requires Java Runtime Environment (JRE) to be installed on the system you are using to remotely manage the connected Dell servers. If the console does not launch with default settings, select Settings and select the Java option. Steps 1. To log in to iDRAC, open a web browser on a management station, and then type the iDRAC IP address in the address bar. 2. On the iDRAC Login page, type the default login credentials: a. In the Username box, type root. b.
Determining OS disk partition sizes Use the table here to determine the partition size for the specific OS disk capacity. For latest information about recommended partition size, see Scality documentation at http://docs.scality.com, and the section Setting Up for Installation on Centos/Redhat. Table 9.
7 Preparing for Scality software installation To prepare for Scality software installation, configure the network interfaces. Configuring network interfaces To configure network interfaces, verify the network interface configuration. Verifying the network interface configuration All components in the ring (Physical Servers, Connectors, and Supervisors) are required to have network connectivity.
