One:

Identify the problem with the disk array first, press and hold ctrl+r after the Dell server is powered on, or F2 Expand the Virtual Disk creation menu

Son, you need to know the following RAID levels when configuring disk arrays:

RAID0 the entire logical disk data is divided by strips (stripped) distributed across multiple physical disks, can be read/write in parallel, providing the fastest speed, but no redundancy, requires at least two disks. With raid 0, we can obtain a larger capacity of a single logical disk and gain higher access speeds by simultaneously reading multiple disks. RAID 0 The first consideration is the speed and capacity of the disk, ignoring the security, as long as one of the disks is a problem, the entire array of data will be out of warranty.

RAID1 is also called mirroring, which is the redundancy of the data, only half of the disk capacity is valid throughout the mirroring process (the other half of the disk is used to hold the data). Compared to RAID 0, RAID 1 first considers security, which is half the capacity and the same speed.

RAID 0+1 in order to be both fast and secure with RAID 10 (or RAID 0+1), RAID 10 can be simply understood as a RAID 0 array composed of multiple disks for mirroring.

RAID 3 and RAID 5 </strong>raid 3 and RAID 5 are all checksum modes. RAID 3 works by storing the checksum data with a disk. Because any data changes to modify the corresponding data check information, the disk that holds the data has several and parallel work, and the disk that holds the check data is only one, which brings the bottleneck of verifying data storage. RAID 5 works by dividing the data generated by each disk into chunks that are stored in the respective disks that make up the array, thus easing the bottleneck that occurs when the checksum data is stored, but the cost of splitting the data and controlling the storage is at a speed.

This great God's blog explains in detail what raid is all about:

Two:

Set up the above situation by Span style= "COLOR: #ff0000" > F11 settings with what boot boot mode with two types of UEFI and BIOS

In popular terms, UEFI is an evolutionary version of the BIOS, compared to the advantages of the BIOS:

1. Improve security by protecting pre-boot or pre-boot processes against Bootkit attacks.

2, shorten the start time and resume from the sleep state time.

3. Supports drives with capacity exceeding 2.2 TB.

4, support 64-bit modern firmware device drivers, the system can use them during the boot process to address more than 17.2 billion GB of memory.

5. UEFI hardware can be used in conjunction with the BIOS.

Note: If the server's hard disk exceeds the 2T capacity, you need to choose UEFI boot, if you do not choose UEFI boot, even if you installed the system, will also appear beyond the 2T capacity can not find

Three:

Make boot disk also need to change the partition format to UEFI format, or it will appear the computer hard disk detection, even if you can install the system, the boot will also be stuck, not to go to the graphical desktop

To do the above steps, the following is the same as the normal system of the same steps
