Managed Resources

Resource Orchestrator can be used to manage the resources described in the table below.

Table 2.3 Managed Resources
Resource	Description
Chassis	A chassis is an enclosure used to house server blades. It can monitor the statuses of servers, display their properties, and control their power states.
Physical server	This is a general term for any physical server. This term is used to distinguish physical servers from virtual machines that are created using server virtualization software such as VMware or Hyper-V. The following usage methods are available for physical servers: Managing unused physical servers as L-Servers by registering them with Resource Orchestrator Managing configured physical servers by linking them to L-Servers VM hosts and physical OSs running on physical servers can be detected and registered as managed resources by Resource Orchestrator.
VM host	This refers to the server virtualization software running on a server to operate a virtual machine. For example, Windows Server 2008 R2 with Hyper-V roles added, VMware ESX for VMware, domain 0 for RHEL5-Xen, VM hosts for RHEL-KVM, Citrix XenServer, OVM for x86, OVM for SPARC, or Global Zone for Solaris Zones. VM hosts can be managed by monitoring their statuses, displaying their properties, and performing operations such as HBA address rename and server switchover. When a VM host is registered, any VM guests on the VM host are automatically detected and displayed in the server tree. The power operations and migration operations, etc. of VM guests can be performed from the server tree.
VM management software	This software manages multiple server virtualization software. For example, for VMware, it is vCenter Server, for Hyper-V, it is SCVMM, and for OVM for x86 2.2 or OVM for x86 3.x, it is Oracle VM Manager. VM management software can be integrated (registered) into Resource Orchestrator to enable the use of functions for VM guests.
Server management software	Software used for managing multiple servers. The target servers can be controlled.
LAN switch blades	The L2 switches that are mounted in a blade server chassis (LAN switch blades). Resource Orchestrator can monitor LAN switch blade statuses, display their properties, and manage their VLAN configurations.
VM guest	This refers to the operating system running on a virtual machine. Resource Orchestrator can monitor VM guest statuses, display their properties, and control their power states. The following usage methods are available for physical servers: Managing new VM guests as L-Servers Managing configured virtual machines by linking them to L-Servers
Virtual switch	This is a virtual switch used to manage a VM guest network on the VM host. In Hyper-V, it represents the concept of virtual networks. It supports virtual switches, which are standard Hyper-V virtual network and VMware functions.
Disk resources	This refers to a disk resource allocated to a server. For EMC CLARiiON storage, EMC VNX storage, ETERNUS storage or NetApp FAS storage The one that corresponds to the disk resource is LUN. For EMC Symmetrix DMX storage or EMC Symmetrix VMAX storage The one that corresponds to the disk resource is device. For Storage Server on which FalconStor NSS operates The one that corresponds to the disk resource is Virtual Device. For VM guests The one that corresponds to the disk resource is virtual disk.
Virtual storage resources	This refers to a resource that can create a disk resource. For example, RAID groups of ETERNUS storage, aggregates of NetApp storage, and file systems for creating VMs (VMware datastores).
Storage management software	Software to manage and integrate one or multiple storage units. For EMC CLARiiON storage or EMC VNX storage The one that corresponds to the storage management software is Navisphere. For EMC Symmetrix DMX storage or EMC Symmetrix VMAX storage The one that corresponds to the storage management software is Solutions Enabler. When Using ETERNUS Storage The one that corresponds to the storage management software is ETERNUS SF Storage Cruiser. For NetApp FAS storage The one that corresponds to the storage management software is Data ONTAP. For Storage Server on which FalconStor NSS operates The one that corresponds to the storage management software is FalconStor NSS. Integration (registration) with Resource Orchestrator enables the use of functions for basic management of storage units.
Network resources	This refers to a resource that defines network information for use by an L-Server or a network device. By connecting the NIC for an L-Server to a network resource, the physical and virtual network switches are configured, enabling the L-Server to communicate. If an IP address range is set for a network resource, the IP address can be automatically set when deploying an image to an L-Server.
Network device resources	This refers to a resource that defines a network device. Firewalls, server load balancers, and L2 switches (except for LAN switch blades) are included. It is possible to monitor the statuses of network devices, display their properties, and perform automatic configuration.
Address set resources	This refers to WWN, MAC address, and global IP addresses. When a physical L-Server is created, a WWN and MAC address are necessary. When a virtual L-Server is created using KVM, RHEL5-Xen, or Citrix Xen, a MAC address is necessary. For automatic configuration of network devices using simple configuration mode, when managing the virtual IP addresses (public addresses) used for address translation functions of firewalls, and performing automatic allocation, global IP addresses are necessary.
Virtual image resources	They are the following two images. Cloning images collected from virtual L-Servers Images using a template used for VM guest creation with VM management software
Physical image resources	Cloning images gathered from physical L-Servers.
