    1.3.3 View Panel The View panel appears below the toolbar. The View panel shows the IP address of each xStack Storage system that has been added to the Management Center (an xStack Storage system must be added to the console in order to be managed by it). In Figure 1-5, for example, two xStack Storage systems have been added to the Management Center, one with an IP address of 192.168.0.34 and another with the IP address 192.168.0.32.

  • Page 37: Chapter 3 Managing Volumes

    Chapter 3 Managing Volumes This chapter describes how to manage volumes on an xStack Storage system. A volume is a set of storage blocks organized and presented for use by a customer’s server (an iSCSI initiator node). The iSCSI initiator node sees the volume as a contiguous series of numbered blocks, called Virtual Logical Block Numbers (VLBNs), in the same way that it would see the storage space on a single disk drive.

  • Page 38: Understanding The Volume View

    3.1 Understanding the Volume View In the Volume View, the Main Display shows information about the volumes on the xStack Storage array. The information shown can be sorted by volume name or by iSCSI initiator using the two radio buttons in the Main Display. By default, the Sort by Volume button is selected (see Figure 3-1).

    6.2 Working with Management Ports The xStack Storage system contains a management port that provides access to the xStack Storage Management Center. In the Network Settings View, the management port associated with the xStack Storage system appears below Network Settings in the Main Display. The following sections describe how to view or change the settings of the management port and how to ping from the management port to check its connection.

  • Page 101: Working With Network Portals

    6.4 Working with Network Portals The iSCSI standard uses the concept of a network entity that represents a device or gateway attached to an IP network. In general, this network entity (either target or initiator) must contain one or more network portals that provide the physical connection to the IP network. An iSCSI node within a network entity can use any of the network portals to access the IP network.

    6.5 Grouping and Ungrouping Ports The xStack Storage Management Center allows you to group individual physical Ethernet ports into a single logical port called a link aggregate group (or “LAG”). Link aggregation is a way to combine (or “aggregate”) multiple data ports in parallel to act as a single logical connection with increased bandwidth, and the xStack Storage system can do this, too, using static link aggregation.

  • Page 105: Grouping Ports

    Figure 6-8. Example of a Group 6.5.1 Grouping Ports The following procedure describes how to group ports. When you group ports, you have the option of creating a VLAN-enabled group. To group ports: 1. In the Network Settings View, click an Ethernet port in the Main Display. 2.

    This “V” Indicates That the Port Selected in the Main Display is VLAN Enabled Figure 6-11. Example of a VLAN-Enabled Port When you VLAN-enable a port or LAG, the portal information associated with the port or LAG is deleted prior to the port or LAG joining the VLAN. As a result, any IP address associated with the port or LAG is removed.
