Chapter 6. RAID

What is RAID
Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with single- drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID array. This array distributes data across multiple storage drives, but the array appears to the host computer as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited I/O performance, because several drives can be accessed simultaneously.
Select RAID mode
You can select the SATA RAID mode or NVMe RAID mode to configure RAID with RAIDXpert2 Configuration Utility.

1. Do one of the following to select the SATA RAID mode or NVMe RAID mode:
   • SATA RAID mode:
   a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
   b. Select Devices ➙ ATA Drive Setup ➙ Configure SATA as (AHCI/RAID).
   c. Select RAID.
   • NVMe RAID mode:
   a. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.
   b. Select Devices ➙ NVMe Setup ➙ NVMe RAID Mode (Enabled/Disabled).
   c. Select Enabled.

2. Press F10 or Fn+F10 to save the changes and exit.

3. Restart the computer. When the logo screen is displayed, press F1 or Fn+F1.

4. Select Devices ➙ RAIDXpert2 Configuration Utility to select drives and configure RAID.

RAID Levels
CAUTION:

• Only one redundant RAID array is supported by AMD-RAID. RAID1, RAID5, and RAID10 are all redundant arrays.
• The AMD-RAID does not support more than eight arrays, including Non-RAID array.
• Multiple operating systems are not supported on AMD-RAID Array. If the system is booted from an AMD-RAID bootable array, the first array in the Arrays section must be the bootable array. The system boots only from the first array in the Arrays section. Refer to “Configure RAID with RAIDXpert2 Configuration Utility” on page 30 to find the first array by viewing array details and checking the array number.

Your computer supports the following RAID levels:

• RAID 0: striped disk array
  – Provide the highest performance but no data redundancy. Data in the array is striped (distributed) across several disks.
  – Support 2-8 disks.
  – RAID 0 arrays are useful for holding information, such as the operating system paging file, where performance is extremely important but redundancy is not.

• RAID 1: mirrored disk array
  – Mirror data on a partition of one disk to another.
  – Support 2 disks.
  – RAID 1 arrays are useful when there are only two disks available and data integrity is more important than storage capacity.

• RAID 5: block-level striped disk array with distributed parity
  – Stripe data as well as parity, across all disks in the array.
  – Support 3-8 disks.
  – Offer exceptional read performance and redundancy.

• RAID 10: striped and mirrored disk array (a combination of RAID 0 and RAID 1)
  – Combine mirrors and stripe sets. RAID 10 allows multiple disk failures, up to 1 failure in each mirror that has been striped.
  – Support 4, 6, or 8 disks.
  – Offer better performance than a simple mirror because of the extra disks. Require twice the disk space of RAID 1 to offer redundancy.

• Volume (JBOD):
  – RAIDXpert2 Configuration Utility treats one or more disks or the unused space on a disk as a single array.
  – Support 1-8 disks.
  – Provide the ability to link-together storage from one or several disks, regardless of the size of the space on those disks. It is useful in scavenging space on disks unused by other disks in the array. It does not provide performance benefits or data  redundancy. Disk failure will result in data loss.

• RAIDABLE (also known as RAID Ready):
  – Allow a RAIDABLE disk to be transformed later to RAID 0 or RAID 1.
  – Support 1 disk.

Configure RAID with RAIDXpert2 Configuration Utility
If your computer comes with the RAIDXpert2 Configuration Utility , you can follow the sections below to configure RAID.
Initialize disks
New disks and legacy disks must be initialized before they can be used to create an AMD-RAID array.
Initialization writes AMD-RAID configuration information (metadata) to a disk.
CAUTION:

• If a disk is part of an AMD-RAID array, the disk cannot be selected for initialization. To initialize the disk anyway, delete the AMD-RAID array. Data on the disk is deleted during initialization so ensure the correct disks are chosen to initialize.

Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can damage the part. When you unpack an option or CRU, do not open the static-protective packaging containing the part until the instructions direct you to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage:

• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective packaging containing the part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the packaging and your body.
• When possible, remove the static-sensitive part from the static-protective packaging and install the part without setting it down. When this is not possible, place the static-protective packaging on a smooth, level surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.

Cleaning and maintenance
With appropriate care and maintenance, your computer will serve you reliably. The following topics offer information to help you keep your computer working with best performance.
Basic maintenance tips
Here are some basic points about keeping your computer functioning properly:

• Keep the computer in a clean, dry environment. Ensure that the computer rests on a flat, steady surface.

• Do not cover any of air vents. These air vents provide airflow to keep the computer from overheating.

• Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and microwave oven away from your computer because the strong magnetic fields generated by these appliances can damage the monitor and data on the storage drive.

• Keep food and drinks away from all parts of the computer. Food particles and spills might make the keyboard and mouse stick and unusable.

• Do not get the power switches or other controls wet. Moisture can damage these parts and cause an electrical hazard.

• Always disconnect a power cord by grasping the plug instead of the cord.

• Keep the computer software, device drivers, and operating system up-to-date.

• Empty your recycle bin on a regular basis.

• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.

• Clean up files and free up storage drive space and memory space occasionally to prevent performance problems.

• Keep a log book. Entries might include major software or hardware changes, device-driver updates, intermittent problems and what you did to resolve them, and other issues you might have experienced.
  The cause of a problem might be change in hardware, change in software, or any other actions that might have taken place. A log book can help you or a Lenovo technician determine the cause of a problem.

• Back up your data on the storage drive regularly. You can restore the storage drive from a backup.

• Create a recovery medium as early as possible. You can use the recovery medium to recover your operating system even if Windows fails to start up.

• Get the most up-to-date operating system update patches, software programs, and device drivers.

Maintenance tips about moving the computer
Before moving the computer, take the following precautions:

1. Back up your data on the storage drive.
2. Remove any media from the drives and turn off all connected devices and the computer. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the computer.
3. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are using different cartons, cushion the units to avoid damage.

When you move the computer to another country or region, you must take local electrical standards into consideration. If the local electrical outlet style is different from the type you are currently using, contact the Lenovo Customer Support Center to purchase either an electrical plug adapter or a new power cord.
Clean your computer
CAUTION:
Remove any media from the drives and turn off all connected devices and the computer. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the computer.
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free operation.
Clean the computer surface: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying liquids directly to the surface.
Clean the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush or use cool air from a hair dryer.
Clean the computer screen: Scratches, oil, dust, chemicals, and ultraviolet light can affect the performance of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a scratchlike mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the stain remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly to your computer screen. Ensure that the computer screen is dry before closing it.

Appendix B. System memory speed

The AMD Threadripper Pro microprocessor families compatible with this ThinkStation computer feature an integrated memory controller, which provides the microprocessor with direct access to the system memory.
Because of this design, the system memory speed will be determined by a number of factors, including the microprocessor model and the type, speed, size (capacity), and number of DIMMs installed.
Notes:

• The actual system memory speed of the memory modules varies depending on the microprocessor model. For example, your computer comes with 2666 MT/s memory modules, but microprocessor only supports up to 2400 MT/s memory modules. Then  the system memory speed will be no faster than 2400 MT/s.
• The microprocessor models supported in your computer might vary. For a list of supported microprocessor models, contact the Lenovo Customer Support Center.
