部署vsphere三大问题

1.what types of servers will i use for the underlying physical hardware?

(如何选择服务器的物理硬件)

2.what kinds of storage will i use,and how will i connect that storage to my servers?

(如何选择存储技术)

3.how will the networking be configured?

(如何配置网络)

选择服务器硬件

compared to "traditional" operating systems like windows or linux,esxi has more stringent hardware restrictions.esxi won't necessarily support every storage controller or every network adapter chipset available on the market.

(相对于传统的os,esxi有更严格的硬件限制,不是所有的存储控制器和网卡都能支持)

hardware compatibility list(hcl)(查找硬件兼容列表)

选择存储架构

vsphere几乎所有高级特性(vmotion,vmware drs,vmware ha,and vmware ft)都需要一个共享式的存储架构.vsphere支持如下三种存储技术:

1.fibre channel-based storage(网状信道)

2.iscsi-based storage(iscsi存储)

3.network file system(nfs)(文件共享)

vmware's hcl isn't just for servers.the searchable hcl also provides compatibility information on storage arrays and other storage components.

常用的fc存储卡(1)

emulex lp10000 2gb pci-e fibre channel

常用的fc存储卡(2)

qlogic qla2344 2gb pci-x fibre channel

如何配置网络适配器

网络适配器(网卡)在vsphere中的5大用途:

1.service console

2.vmotion(建议至少是gigabit ethernet)

3.vmware ft(建议至少是gigabit ethernet)

4.iscsi or nfs(建议至少是gigabit ethernet)

5.traffic originating from the virtual machines themselves(建议至少是gigabit ethernet)

建议都应该考虑冗余(所以一台server建议配置10个gigabit ethernet口)

常用的以太网卡

intel 8492mt dual port pci-x adapter

intel pro1000pt 9402pt dual port pci-e adapter

esxi对英特尔网卡几乎所有型号兼容性都比较好,在不确定的情况下保险起见尽量选择因特尔网卡.
