Lesson5 vSphere 5.0 存儲

1. Fibre Channel

2. 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中支援的最大LUN大小僅為2TB（選擇最大的8MB的塊大小）.

VMFS-5支援的LUN大小最大可達64TB.

vSphere 5.0可以線上平滑地将VMFS-3更新到VMFS-5.

添加一塊硬碟後，應該注意它能否被驅動，最好在’資料存儲’檢視下 裝置運作情況

當然你也可以解除安裝掉硬碟

等分離過程後，你就可以熱拔插硬碟了

Nfs 是unix系統間實作磁盤檔案共享的一種方法

這裡不作示範

ISCSI SAN使用的是用戶端-伺服器架構

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.

4-2-1建立 iscsi的 vmkernel端口

<a href="http://s3.51cto.com/wyfs02/M02/6E/96/wKioL1WA2WDiYxSrAAC_ROBbJeE933.jpg" target="_blank"></a>

4-2-2添加iscsi 擴充卡

将ISCSI擴充卡邦定到一個或者多個vmkernel擴充卡 ，對于從屬硬體iscsi擴充卡，隻能使用一個與正确的實體網卡關聯的 vmkernel接口

這邊用win server 2012 作 iscsi target

當啟用storage I/O control後,esxi 會開始監控主機與該資料存儲通信時主機遵循的裝置滞後時間.
