Windows Server 2016 Storage Pool functional configuration Test
This document mainly tests that the Windows server has its own function-"Storage Pool", which can effectively avoid the loss of data when the hard disk fails without the Raid card function in the server hardware. This feature is similar to the Jbod,raid1,raid5 mode in Raid.
I. Test environment
Server model: VM200G
Server system: Windows Server 2016
Hard disk: SAS 500GB * 4 (storage pool), SAS 300GB*2 (system disk)
Second, configure storage pool 1. Disk preparation
You can see that there are four available disks in RAID management
Before using, you need to initialize these disks to JBOD mode, otherwise the system cannot directly recognize them.
After initialization, you can search for 4 new disks in computer-managed disk management
two。 Create a disk pool
Open * * Server Manager * *-> * * File and Storage Services * *. Under the * * disks * * option, you can see all disks. Here you can see 4 disks in 600G/GPT format (GPT format is created when the disk is initialized in computer Management).
In the "Storage Pool" option, right-click in the empty space-create a new storage pool
Enter the name of the storage pool, and then next
In the physical disk option, select the hard disk you want to add to the storage pool. Here, four 600g hard disks are selected, and "automatic" is selected in the allocation.
After confirmation, click "create"
As follows, the storage pool has been created
3. Create a virtual disk
In the Virtual disk tab, select Task-New Virtual disk
Select the corresponding storage pool. There is only the one that has just been created.
In the wizard, enter a name for the virtual disk
In "Storage data layout", select the appropriate layout (Simple/Mirror/Parity)
Simple: just like JBOD mode, use the corresponding disk directly without backup redundancy
Mirror: similar to Raid1, you can perform 1:1 or 1 N backup redundancy
Parity: similar to Raid5, more than three disks form disk groups, and data and parity are distributed on different physical disks. It not only avoids the waste of disk space in Mirror mode, but also realizes disk redundancy.
In Settings, select the type of volume (simplified / fixed), where fixed is selected and allocated according to the actual space
In setting the volume size, you can specify the allocation size, or you can directly use the maximum size (that is, all available space), which is selected here
After confirmation, click "create"
Complete the creation of the virtual disk as follows
4. Initialize virtual disk
After creating the virtual disk above, the original four new disks have been merged into one disk in the computer management of the server, as shown in the following figure
Select the newly created disk, right-click to create a partition and use it normally. In the computer, you can see that the new disk has been added successfully, as shown in the following figure
Second, test storage pool redundancy 1. Plug and pull plate test
The virtual disk created in Party's mode is selected here, so this virtual disk is redundant. The following is the test:
a. Status of storage pool virtual and physical disks before testing
b. Speed test, copy data from other servers locally, at the following speed
c. During the copy process, unplug the Slot7 hard disk without interruption and speed.
d. At this point, check that the status of the storage pool and virtual disk is degraded, and the abnormal alarm of the physical disk in the storage pool
e. After reinserting the hard disk, wait for the virtual disk to be repaired automatically (or right-click on the corresponding virtual disk and select "repair this virtual disk"), and wait for the repair progress in the virtual disk state to be 100%.
two。 Add hot spare test
The main test here is that when a hard disk fails to replace a new disk, the speed of data synchronization is about 1.2T.
Unplug one of the hard drives, storage pool and virtual disk display abnormal alarm, and virtual disk status is degraded
At this point, insert a new hard disk and select "add physical disk" in the storage pool (note: if it is a new disk, it needs to be initialized in computer management)
After the addition is complete, you can see the newly added hard disk in the physical disks tab
By default, there is no way to repair the virtual disk. Only after executing the following command can you use the repair virtual disk function to repair and synchronize the virtual disk.
After right-selecting "repair Virtual disk" on the virtual disk, the virtual disk begins to repair synchronously.
Synchronization completed and virtual disk status returned to normal (data synchronization takes about 1 hour)
Today, I did this simple test, which basically met the expectations and can be used in business.
