B.2 ICT Resources

This section explains the ICT resources that are managed by this product.

Refer to "Chapter 3 System Design and Initial Setup" of the "ServerView Resource Coordinator VE Setup Guide" for information on managing chassis, VM hosts, VM management products and LAN switches,

Table B.3 ICT resources
Resource	Content
Chassis	The chassis of a blade server that houses one or more server blades. This product can monitor the status of chassis, display information about chassis, and manipulate the power to chassis.
VM host	A server virtualization software product that runs on a server in order to enable Virtual Machines(Virtual Server) to run. Examples of VM hosts are VMware ESX by VMware, and Windows Server 2008 R2 with a Hyper-V role added. This product can monitor VM hosts, display information about VM hosts, and perform server switching operations. When a VM host is registered, the VM guests running on the VM host are automatically detected and displayed.
VM management product	A product that performs integrated management for multiple server virtualization software products. Examples of VM management products are VMware vCenter Server for VMware and SCVMM for Hyper-V. Registering and linking VM management products with this product enables their functions to be used on VM guests.
LAN switch	The term "LAN switch" refers to both the LAN switches that are installed in the chassis of blade servers (which are known as "LAN switch blades") and to the LAN switches that these LAN switch blades are connected to. This product can monitor the status of LAN switch blades, display information about LAN switch blades and set up VLANs. This product can display the following information about LAN switch blades and other LAN switches via the RCVE network map function. Refer to "Chapter 12 Network Map" in the "ServerView Resource Coordinator VE Operation Guide" for details. The network configuration within a virtual server (the virtual switch and the VM guest) The network connection status between resources The VLAN setup status within virtual servers
VM guest	The operating system that runs on a Virtual Machine(Virtual Server). This product can monitor the status of VM guests, display information about VM guests, and manipulate the power to VM guests. In addition to the functions of ServerView Resource Coordinator VE, this product provides functions such as creating new VM guests as L-Servers, and creating snapshots.
Virtual switch	A virtual LAN switch that is used to manage the networks for VM guests running on a VM host. With Hyper-V, this concept is expressed by the term "virtual network". This product supports both Hyper-V virtual networks and VMware virtual switches (provided as a standard VMware function). This product does not support VMware vNetwork Distributed Switches or Cisco Nexus 1000V virtual switches.
Disk resource	Disk resources that are allocated to servers. An example of a disk resource is a virtual disk.
Virtual storage resource	A resource that enables disk resources to be pulled out dynamically. An example of a storage resource is the file system for creating virtual machines (such as VMFS data stores by VMware). Disk resources can be created from RAID groups of ETERNUS storage and file systems for creating VM.
Network resource	Resources that define information about the networks that L-Servers use. By connecting an NIC for an L-Server to a network resource, physical and virtual network switches are set up so that the L-Server can communicate. If an IP address range has been specified for a network resource, IP addresses can be set up automatically when images are distributed to L-Servers.
Virtual image resource	An image that is created using a template from a VM management software for VM guest creation, or that is collected as a cloning image from an L-Server.
