Page 4: Welcome To Dx Storage
Chapter 1. Welcome to DX Storage DX Storage is a high-performance, massively scalable, self-managing, cost-effective, fixed content storage software that runs on clusters of standard x86 computer hardware. DX Storage provides the integrity of an archive with the performance of primary storage. 1.1. -

Page 7: Layer 3 Switching And Routing
2.1.2. Layer 3 Switching and Routing A router or a layer 3 switch routes network packets between subnets. A router segregates network traffic by filtering packets based on the subnet to which they are addressed. This segregation is important so 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. - 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 a switch failure.

switches, the network connection between switches must be faster than the individual ports. Contact your switch provider for information about proprietary software 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. -
Page 10: Network Summary
The following networking services are recommended for the management of a DX Storage cluster. • DHCP server for allocating node addresses • NTP time server to provide clock synchronization. Dell recommends you configure multiple NTP servers (or multiple pools of servers) that are located in the proximity of your cluster. Clock synchronization is critical for many of DX Storage's components. -
Page 11: Setting Up Ntp For Time Synchronization
Although client applications can initiate first contact with any node in the DX Storage cluster – even choosing to access the same node every time - Dell recommends that the node of first contact be evenly distributed around the cluster. -
Page 12: Preparing For Named Objects
IN A 192.168.1.103 In the preceding example, it is important that the time to live (TTL) value for each of the records in the round-robin group is very small (0-2 seconds). This is necessary so that clients that cache the resolution results will quickly flush them. -
Page 13: Setting Up Network Load Balancing
• If you boot from a CSN, an aggregate MIB for the entire cluster is available in /usr/share/ snmp/mibs. • If you do not boot from a CSN, the MIB is located in the root directory of the DX Storage software distribution. -

• USB boot loader example. Following is an example section of the syslinux.cfg that is contained in the root directory on the USB flash drive. label normal kernel kernel append initrd=fsimage ramdisk_size=128000 root=/dev/ram0 castor_cfg=http://172.16.1.200/castor/cfg-list.txt Note The append command must be entered on a single line. It is shown here on multiple lines because of space limitations. -

• pxelinux.cfg if the node is booting from the network In the configuration file, a kernel parameter named castor_net is included in the append clause. castor_net enables you to specify both the bonding mode for the adapters as well as a comma- separated ordered list of the network devices that DX Storage can use, where the first device in the list is the preferred interface that will be used whenever it is on-line. -

Stream Size Guidance This section provides guidelines you can use to size storage volumes for large stream sizes. The largest object a DX Storage cluster can store is one-fifth the size of the largest volume in the cluster. -

Because DX Storage must maintain the correct number of replicas in the subcluster, retiring a volume without sufficient space can be problematic.

Chapter 4. Installing and Configuring DX Storage This chapter discusses how to set up and configure a basic DX Storage cluster. Note If you boot DX Storage from a Cluster Services Node (CSN), the required infrastructure setup, installation and configuration updates are performed automatically as part of CSN configuration so the tasks discussed in this chapter are not necessary or recommended. -

Page 26: Dhcp Or Static Network
When using the all keyword, DX Storage automatically excludes the DX Storage USB flash drive from being used for storage. To explicitly set the disk device names, set vols to a space-separated list of drive identifiers. DX Storage uses standard Linux volume identifiers like /dev/sda, /dev/sdb, and so on. If you are not sure what your volume identifiers are, you can access the DX Storage node using another Linux system. -
Page 27: Using Syslog
After the hardware self-test, the DX Storage operating system boots and prints an on screen message that says the storage node is running. This on screen message confirms that the node has booted completely and displays the IP address for the node. 4.4. -
