1.1 Creating Storage Pool Space

After users complete the hard drive installation and enter the NAS system for the first time, Zettlab AI NAS will remind you to create storage pools with various RAID modes (RAID mode can recover data using new hard drives when some hard drives are damaged, better protecting your data security). Special reminder: The process of creating a storage pool will format the disk. If the disk contains important files, please back up the hard drive files first, and confirm that there is no risky data on the hard drive before installing it in the NAS.

1. After logging in to Zettlab AI NAS, open the [Settings] application at the bottom of the main interface.
2. After entering the page, click [Storage] > [Storage Pool] > Continue to click [+Create Storage Pool] in the upper right corner.
3. First select the disks to form a Storage Pool on the left, and the right will display the available storage pool modes based on the number of selected disks. You can choose the appropriate mode based on data protection, performance priority, or storage space priority (how to choose RAID mode). After selecting the storage mode, click [Next] in the lower right corner. *SSD only supports Basic mode and JBOD mode.
4. You can set the capacity for the user, then continue to click [Next] in the lower right corner. *If the administrator user does not set it, the default is maximum capacity. *If ordinary users do not set it, the default is no usage capacity.
5. After ensuring that the disk has no important files, click [Format] > Enter password > Click [Format] again. *Special reminder: The process of creating a storage pool will format the disk. If the disk has important files, please complete the backup before installing it in the NAS.
6. Wait for 2-5 minutes, creation completed. Creating Creation completed

1.2 Selecting RAID Mode

Choose the appropriate storage mode according to specific needs to balance performance, capacity, and data security. The following are detailed introductions to several storage modes: Basic, JBOD, and RAID 0, 1, 5, 6, 10:

1. Basic (Single Disk Mode)
   • Principle: Use a single hard drive to store data, without redundancy or striping.
   • Advantages:
     • Simple and easy to use, no complex configuration required.
     • Low cost, suitable for small-scale storage needs.
   • Disadvantages:
     • No redundancy, hard drive failure will lead to data loss.
     • Limited performance, unable to utilize parallel read/write of multiple disks.
   • Applicable Scenarios: Personal users, small storage needs, or scenarios with low requirements for data security.
2. JBOD (Just a Bunch of Disks)
   • Principle: Combine multiple hard drives into one logical volume, data is stored sequentially, without redundancy or striping.
   • Advantages:
     • Fully utilize all hard drive capacities.
     • Simple configuration, suitable for expanding storage space.
   • Disadvantages:
     • No redundancy, any hard drive failure will lead to partial data loss.
     • No performance improvement, unable to utilize parallel read/write of multiple disks.
   • Applicable Scenarios: Scenarios that require large-capacity storage and have no requirements for performance and data redundancy.
3. RAID 0 (Striping)
   • Principle: Data is divided into blocks and alternately stored on multiple hard drives.
   • Advantages:
     • Significantly improves read/write performance (parallel operations on multiple disks).
     • High storage space utilization (no redundant data).
   • Disadvantages:
     • No redundancy, any hard drive failure will lead to all data loss.
   • Applicable Scenarios: Scenarios with high performance requirements and low data security requirements, such as video editing, temporary caching.
4. RAID 1 (Mirroring)
   • Principle: Data is completely copied to multiple hard drives, each hard drive stores the same data.
   • Advantages:
     • High data security (when one hard drive fails, data can still be recovered from other hard drives).
     • Improved read performance (can read from multiple hard drives simultaneously).
   • Disadvantages:
     • Low storage space utilization (for example, two hard drives can only use half the capacity).
     • No improvement in write performance (data needs to be written to multiple hard drives).
   • Applicable Scenarios: Scenarios with high data security requirements, such as financial systems, databases.
5. RAID 5 (Striping with Parity)
   • Principle: Data is divided into blocks and stored on multiple hard drives, while storing parity information (used for data recovery).
   • Advantages:
     • Balances performance and data security (allows one hard drive to fail).
     • High storage space utilization (only loses one hard drive capacity for parity).
   • Disadvantages:
     • Lower write performance (needs to calculate parity).
     • Significant performance degradation when rebuilding data.
   • Applicable Scenarios: Scenarios with moderate requirements for performance and security, such as file servers, small and medium-sized databases.
6. RAID 6 (Dual Parity Striping)
   • Principle: Similar to RAID 5, but uses two sets of parity information, allowing two hard drives to fail simultaneously.
   • Advantages:
     • Higher data security (allows two hard drives to fail).
     • Still high storage space utilization (only loses two hard drive capacities for parity).
   • Disadvantages:
     • Even lower write performance (needs to calculate two sets of parity).
     • More significant performance degradation when rebuilding data.
   • Applicable Scenarios: Scenarios with extremely high data security requirements, such as large databases, critical business systems.
7. RAID 10 (Mirroring + Striping)
   • Principle: Combines RAID 1 (mirroring) and RAID 0 (striping), first groups hard drives for mirroring, then stripes the groups.
   • Advantages:
     • High performance (striping improves read/write speed).
     • High data security (allows one hard drive to fail in each mirror group).
   • Disadvantages:
     • Low storage space utilization (can only use half of the total capacity).
     • Higher cost (requires at least 4 hard drives).
   • Applicable Scenarios: Scenarios with extremely high requirements for both performance and data security, such as databases, virtualization platforms.

1.3 SSD Cache Management

SSD cache (also known as flash cache) is a cost-effective solution that improves the performance of HDD arrays by storing the most frequently accessed data on SSDs. You can create an SSD cache on a storage pool to improve random read/write performance of files. Zattlab AI NAS supports two cache modes: read-only cache and read-write cache. Read-write SSD cache always has redundancy functionality. At least 1 SSD is required to create a read-only cache, while read-write cache requires at least 2 SSDs. Please note: This mode is only supported for setting up SSD cache on storage pools created with SATA mechanical disks, and each storage space can only configure one SSD cache.

1.4 Creating SSD Cache
