Lesson5 vSphere 5.0 存储
1- ESXi支持的存储选项
1. Fibre Channel2. Fibre Channel over Ethernet
3. iSCSI using software and hardware initiators
4. NAS (specifically, NFS)
5. Local SAS/SATA/SCSI storage
6. InfiniBand
VMFS-3中支持的最大LUN大小仅为2TB(选择最大的8MB的块大小).
VMFS-5支持的LUN大小最大可达64TB.
vSphere 5.0可以在线平滑地将VMFS-3升级到VMFS-5.
2-esxi添加本地磁盘
添加存储器
添加一块硬盘后,应该注意它能否被驱动,最好在’数据存储’查看下 设备运行情况
当然你也可以卸载掉硬盘
等分离过程后,你就可以热拔插硬盘了
3-添加 nfs 存储
Nfs 是unix系统间实现磁盘文件共享的一种方法这里不作演示
4-添加外置iSCSI 存储
ISCSI SAN使用的是客户端-服务器架构4-1iSCSI术语An iSCSI initiator is a logical host-side device
that serves the same function as a physical host
bus adapter in Fibre Channel or SCSI/SAS.
iSCSI initiators can be software initiators,The
other form of iSCSI initiators are hardware
initiators. An iSCSI initiator is identified by an
iSCSI qualified name. An iSCSI initiator uses an
iSCSI network portal that consists of one or more
IP addresses. An iSCSI initiator ‘‘logs in’’ to an
iSCSI target.
An iSCSI target is a logical target-side device
that serves the same function as a target in Fibre
Channel SANs. It is the device that hosts iSCSI
LUNs and masks to specific iSCSI initiators.An
iSCSI target is identified by an iSCSI Qualified
Name. An iSCSI target uses an iSCSI network
portal that consists of one or more IP addresses.
iSCSI Logical Unit (LUN) An iSCSI LUN is a
LUN hosted by an iSCSI target. There can be
one or more LUNs ‘‘behind’’ a single iSCSI target.
iSCSI network portal An iSCSI network portal is
one or more IP addresses that are used by an
iSCSI initiator or iSCSI target.
iSCSI Qualified Name (IQN) An iSCSI qualified
name (IQN) serves the purpose of the WWN in
Fibre Channel SANs; it is the unique identifier for
an iSCSI initiator, target, or LUN. The format of
the IQN is based on the iSCSI IETF standard.
Static/dynamic discovery iSCSI uses a method
of discovery where the iSCSI initiator can query
an iSCSI target for the available LUNs. Static
discovery involves a manual configuration,
whereas dynamic discovery issues an iSCSIstandard
SendTargets command to one of the
iSCSI targets on the array. This target then
reports all the available targets and LUNs to that
particular initiator.
4-2添加外置的iSCSI存储环境
4-2-1创建 iscsi的 vmkernel端口
4-2-2添加iscsi 适配器将ISCSI适配器邦定到一个或者多个vmkernel适配器 ,对于从属硬件iscsi适配器,只能使用一个与正确的物理网卡关联的 vmkernel接口
4-2-3添加iscsi存储
添加存储,发现磁盘
这边用win server 2012 作 iscsi target
4-3 ISCSI负载均衡
5-存储I/O的配置
当启用storage I/O control后,esxi 会开始监控主机与该数据存储通信时主机遵循的设备滞后时间.5-1针对数据存储器用storage I/O Control
5-2针对虚拟机设置
