About DX Storage in the Network The following topics in this - Dell DX6004S | DX Object Storage Getting Started Guide - Page 6
The next figure shows a more sophisticated network topology that uses a router to separate traffic between the DX Storage nodes and the rest of the network. Copyright © 2010 Caringo, Inc.

that DX Storage nodes have predicable network bandwidth for their use and so that their multicast and unicast traffic doesn't interfere with computers on the rest of the network. 2.1.3. Switching Hardware When selecting Ethernet switching hardware, consider that many client workstations have 100Mbps - Dell DX6004S | DX Object Storage Getting Started Guide - Page 8
With more sophisticated switching hardware, the network segments can be isolated as different Virtual LANs (VLANs) on the same device. Additionally, some enterprise-class switching hardware has routing capabilities. You can also design the DX Storage subnet to use redundant switches in the event of - Dell DX6004S | DX Object Storage Getting Started Guide - Page 9
or use a mechanism such as link aggregation. 2.1.4. Internet Deployments Network security is one of the top considerations during the deployment of any service on the Internet or within an extensive enterprise WAN. In these types of deployments, put a firewall or filtering router in front of DX - Dell DX6004S | DX Object Storage Getting Started Guide - Page 10
Optional Optional 2.2.2. Recommended Infrastructure The following networking services are recommended for the management of a DX for allocating node addresses • NTP time server to provide clock synchronization. Dell recommends you configure multiple NTP servers (or multiple pools of servers) that - Dell DX6004S | DX Object Storage Getting Started Guide - Page 11
DX Storage from a CSN, the CSN provides NTP services for all DX Storage nodes and no further configuration names, you can use NTP pool servers. Dell recommends you use pool servers that are close to causes time to wrap in the year 2036. If a computer's BIOS clock is set beyond this wrap point, NTP - Dell DX6004S | DX Object Storage Getting Started Guide - Page 12

to boot a cluster from the network using Intel's Preboot Execution Environment (PXE) specification. This is commonly referred to as "network booting" and is supported by most modern network adapters.

, the tasks discussed in this section are not necessary or recommended. Your system is already set up to PXE boot from the CSN. DX Storage supports centralizing the node configuration files on an HTTP or FTP server. This method of booting can be used with network booting or with standard USB - Dell DX6004S | DX Object Storage Getting Started Guide - Page 16

IGMP Snooping Support Managed switches commonly make use of IGMP snooping in order to direct multicast traffic to their ports. By default, DX - Dell DX6004S | DX Object Storage Getting Started Guide - Page 18
node hardware should be configured to boot either from the USB flash drive or to PXE network boot (which is the default if using a Cluster Services Node). See Section 2.4, "Setting Up PXE Booting" for more information about setting up PXE booting.

Similar to location based separation in a rack. The network - Dell DX6004S | DX Object Storage Getting Started Guide - Page 21
