Java如何获取VMware中Vcenter/ServerInstance下的各种硬件信息
用Java来获取VMware ESX Server的信息可以通过一个第三方jar包进行方便的操作：
Vijava – Vmware infrastructure(vSphere) java API
关于ESX Server的介绍，可以参照我的另一篇博客：http://josh-persistence.iteye.com/admin/blogs/1887722
下面看看一些相关介绍，然后再看对应的程序：
1. VCenter/ServiceInstance Strucutre
1). ServiceInstance -- Root of the inventory; created by vSphere. (VCenter)
2). Datacenter -- A container that represents a virtual data center. It contains hosts, network entities, virtual machines and virtual applications, and datastores.
3). ComputeResource -- A compute resource (either a cluster or a stand-alone host) （Cluster)
4). HostSystem -- A single host (ESX Server or VMware Server).
5). AboutInfo -- This data object type describes system information including the name, type, version, and build number. (HostSystem/ESX Server/VMware Sever’s AboutInfo)
<!--[if !supportLists]-->1. 2. Below are EsxServer/HostSystem properties is returned from Vijava.
3. 进一步了解ESXServer的Strutcture
EsxServer contains several vm(Virtual Machine of EsxServer), EsxServer and vm’ relationships set on Network(network of EsxServer), Network contains Virtual NIC, Virtual Switch. Virtual Switch is responsible for assigning Physical NIC to VM, just like the VM has its own NIC(Virtual NIC). There have to consider VM and NIC’s relationship, because the NIC may be assigned to one of the VM unexpectedly which means the VM can be related to different Virtual NIC.
从上面的架构图可看出，如果我们需要获取VCenter，ESXServer等的信息，就包括获取Disk/Volumn/Storage, 虚拟交换机，内存，虚拟网卡，物理网卡，内存等信息，最主要的是由于物理网卡通过虚拟交换机分配给每个虚拟主机作为虚拟网卡，这种关系是随机的，或者说有一定的分配规则的，我们在每次获取VCenter的信息时，都需要重新的去获取物理网卡的分配。
下面就是一个实例，该实例展现了怎样从VMware上通过vSphere提供的API（vijava.jar)来获取VCener/ServerInstance下的所有信息，包括上面2. Below are EsxServer/HostSystem properties is returned from Vijava.中列的所有信息。更多的API，可以参照：http://pubs.vmware.com/vsphere-50/index.jsp
