1
00:00:01,040 --> 00:00:03,080
Configure Disks and Volumes.

2
00:00:03,080 --> 00:00:06,990
I think the purpose of this exam objective is just to make sure

3
00:00:06,990 --> 00:00:09,540
you understand the fundamental vocabulary.

4
00:00:09,540 --> 00:00:10,070
Specifically,

5
00:00:10,070 --> 00:00:14,610
a disk is going to be our physical storage devices in Windows Server.

6
00:00:14,610 --> 00:00:19,230
We're talking about connection technologies like SCSI, SAS, SATA.

7
00:00:19,230 --> 00:00:22,640
And these physical storage devices can be partitioned.

8
00:00:22,640 --> 00:00:26,330
In fact, you're going to create one or more partitions on these disks,

9
00:00:26,330 --> 00:00:30,930
and then those partitions can then in turn be created as volumes.

10
00:00:30,930 --> 00:00:31,810
What is a volume?

11
00:00:31,810 --> 00:00:34,900
A volume is nothing more than a formatted disk partition.

12
00:00:34,900 --> 00:00:37,700
This is going to be where the operating system lays

13
00:00:37,700 --> 00:00:41,710
down a file system like NTFS or ReFS, and in Windows,

14
00:00:41,710 --> 00:00:45,530
you wind up with a drive label and a drive letter that serves as

15
00:00:45,530 --> 00:00:47,700
the mount point for that volume in the OS.

16
00:00:47,700 --> 00:00:49,000
Why do I say this?

17
00:00:49,000 --> 00:00:53,150
Well, it really feeds in as a nice entree into the rest of this lesson.

18
00:00:53,150 --> 00:00:57,770
You might have heard of dynamic disks if you've been with Windows for a while.

19
00:00:57,770 --> 00:01:01,220
There used to be a distinction between basic disks and dynamic.

20
00:01:01,220 --> 00:01:06,830
And dynamic unlocked things like software RAID and stretched volumes and so on.

21
00:01:06,830 --> 00:01:09,020
But you should know, if you don't already know,

22
00:01:09,020 --> 00:01:13,320
that dynamic disks are deprecated both in Windows Server and Windows client,

23
00:01:13,320 --> 00:01:16,290
and we just keep disks in the basic orientation.

24
00:01:16,290 --> 00:01:20,000
There still is the capacity to do dynamic and basic.

25
00:01:20,000 --> 00:01:23,010
I think that's just there for backward compatibility.

26
00:01:23,010 --> 00:01:26,540
Microsoft recommends if you have any servers with dynamic

27
00:01:26,540 --> 00:01:28,610
disks, you convert them back to basic.

28
00:01:28,610 --> 00:01:32,660
Now rather than just deal with disks and volumes one at a time,

29
00:01:32,660 --> 00:01:37,270
we're concerned with ways that we can do mirroring and striping and parity,

30
00:01:37,270 --> 00:01:42,290
the so‑called redundant array of independent disks or RAID configurations.

31
00:01:42,290 --> 00:01:47,030
But at the same time, we have to remember that we're dealing with number one,

32
00:01:47,030 --> 00:01:49,440
Microsoft and Microsoft Windows specifically,

33
00:01:49,440 --> 00:01:52,910
so we're not going to be dealing with third‑party hardware OEMs.

34
00:01:52,910 --> 00:01:56,470
Number two, we have to think that we're in a hybrid cloud orientation,

35
00:01:56,470 --> 00:01:59,990
so we're doing software‑defined volume management that

36
00:01:59,990 --> 00:02:02,840
potentially we could do with our Azure VMs,

37
00:02:02,840 --> 00:02:09,000
as well as those that we manage on‑premises, whether those are VMs or physical servers.
