RAID Types & RAID Calculator (What RAID level to choose for a server?).

 

  • What RAID level should I choose for a server? What kind of RAID on a server?
            It all depends on the application and budget.
  • Does RAID make sense?
            Yes it makes sense, any level of redundancy protects services and data from failures. RAID is only of one component to ensure service continuity and data security. However, it does not protect against intentional data deletion, theft, or destruction.
  • Which RAID is the most secure?
            RAID 60, RAID 50, RAID 10 are characterized by a high degree of data protection. The highest level of protection is provided by RAID 60, but its implementation is the most expensive.

 

 

Selecting the Right RAID Level
RAID level Minimum number of drives (N) Maximum number of drives that can fail without data loss Method Capacity Reading speed Prędkość zapisu Application
JBOD A JBOD solution combines two or more drives to form a storage pool. JBOD storage pools do not provide data redundancy. The available capacity of a JBOD storage pool is equal to the total capacity of all disks included in the storage pool. JBOD supports the pooling of disks of different sizes.
 0 2 0 Striping (speed) 100% Excellent Excellent High throughput workstations
 1 2 1 Mirroring (redundancy) 50% Very good good Operating system, entry level applications
 5 3 1 Striping and distributed parity (fault tolerance) n-1 (67-94%) Very good good Data, web servers, media servers
6
4 2 Striping with dual distributed parity n-2 good good High fault tolerance
 10 4 1 per mirror set Striping across mirrors 50% Very good good Databases, file server, email servers
 50 6 1 per R5 set Striping across R5 arrays  n-2 (67-94%) Excellent Very good Databases, file server, email servers
 60 8 2 per R6 set Striping across R6 arrays n-4 (50-88%) Very good good Critical data

 

RAID Calculator

The RAID calculator calculates array characteristics based on data such as number, capacity and speed of disk, RAID type and share of read and write operations.
