ESXi 5.1 後加硬碟機~

請問ching, ESXi 5.1後加3TB HDD, 如何 mount 上VM上面呢?

已經試過響VM內新增HDD, 但最多2TB......

"a single HDD can still only be 2TB minus 512bytes, if carved off a VMFS LUN.  If you use a RDM in physical compatibility mode, you can go to 64TB"



you cannot present a HDD to a guest that exceeds the 2TB minus 512bytes limit.  RDMs are the exception.

see, http://www.vmware.com/pdf/vspher ... ration-maximums.pdf

However, if you are asking about LUN size, yes that has increased to 64TB.


You can create a VMFS5 datastore on that 3TB drive. A virtual machine residing on that datastore cannot have a .vmdk larger than the 2TB-512bytes limit, though. The only time a virtual machine can have a .vmdk larger than that is if it is a physical RDM.



...... 用 physical RDM

回復 6# jeffreycheng

By Default ESX will not allow RDM for local disk.
Follow this link (very detail step)

RDM speed faster then VMFS and reduce overheah to ESX.
I use 4 X 3T RDM to Solaris form ZFS to my home NAS.
Performance is very good!!

先在此謝過 lwyk 及 tjan 兩位 ching 指點, 琴晚成功用 vmkfstool mount 起 3T HDD, 但係就引發另一個迷思......

因為「周姐倫OS」o既關係, 想話代替原用5年嘅Synology DS209+II, 雖然成功安裝「周姐倫OS」,但係個心始終形住佢唔係咁穩定, 唔知有無邊d NAS Server for Linux 可以介紹吓呢? (FreeNAS 測試中~~~)

唔係喎, 我公司個 SAN 係 6TB, 用 VMFS5 可以比一個 3TB 既 Lun 喎.....

一定唔會用freeNAS
我用左2日時間做POC
穩定性低
black list
可以輕易搞到個RAID 死左rebulid 唔返
