The RAID controller - Dell PowerVault MD3220i | Owner's Manual - Page 37
and Concepts This chapter explains terms and concepts used for configuration and operation of MD3200i Series storage arrays. Physical Disks, Virtual Disks, and Disk Groups Physical disks in your storage array provide the physical storage capacity for your data. Before you can begin writing data - Dell PowerVault MD3220i | Owner's Manual - Page 38
MD3200i storage enclosure must contain at least two physical disks for proper operation. This is necessary because the physical disks are used to store configuration information. Physical Disk States The storage array incorrect drive type or drive size MD3200i Series Storage Array Terms and Concepts - Dell PowerVault MD3220i | Owner's Manual - Page 39
The storage array monitors all attached drives and notifies you when a predicted failure is reported by a physical disk. Virtual Disks and Disk Groups When configuring a storage array, you must be created before mapping virtual disks. Planning: MD3200i Series Storage Array Terms and Concepts 39 - Dell PowerVault MD3220i | Owner's Manual - Page 40
to occur simultaneously and improve performance. • Storing redundant data on multiple physical disks using mirroring or parity supports reconstruction of lost data if an error occurs, even if that error is the failure of a physical disk. 40 Planning: MD3200i Series Storage Array Terms and Concepts - Dell PowerVault MD3220i | Owner's Manual - Page 41
level based on the type of application, access, fault tolerance, and data you are storing. The storage array supports RAID levels 0, 1, 5, 6, and 10. The maximum number of physical disks that can be , but also the highest disk overhead. Planning: MD3200i Series Storage Array Terms and Concepts 41 - Dell PowerVault MD3220i | Owner's Manual - Page 42
is utilized for mirroring. This leaves the remaining half of the physical disk capacity for actual storage. RAID 10 is automatically used when a RAID level of 1 is chosen with four or because striped disks are accessed simultaneously. 42 Planning: MD3200i Series Storage Array Terms and Concepts - Dell PowerVault MD3220i | Owner's Manual - Page 43
data in a redundant array (RAID levels 1, 5, 6, and 10). For example, in a system with parity, checking consistency involves computing the data on one physical disk and comparing the results to the contents of the parity physical disk. Planning: MD3200i Series Storage Array Terms and Concepts 43 - Dell PowerVault MD3220i | Owner's Manual - Page 44
physical disk is a serious problem, because the system does not have the redundancy to recover the data. Media Verification Another background task performed by the storage array is media verification of all configured physical disks in a disk group. The storage array uses the Read operation to - Dell PowerVault MD3220i | Owner's Manual - Page 45
factors as the RAID level and expected usage. You can change the default value if segment size usage does not match your needs. When considering a segment-size change, two scenarios illustrate different approaches to the limitations: Planning: MD3200i Series Storage Array Terms and Concepts 45 - Dell PowerVault MD3220i | Owner's Manual - Page 46
of active, concurrent disk group processes per installed RAID controller module is one. This limit is applied to the following disk group processes: 46 Planning: MD3200i Series Storage Array Terms and Concepts - Dell PowerVault MD3220i | Owner's Manual - Page 47
• Segment size migration • Disk group expansion • Disk group defragmentation. The priority of each of these operations can be changed to address performance requirements of the environment in which the operations are to be executed.

However, if you are migrating from any device other than a MD3200i Series Storage Array, the MD3200i array does not recognize the migrating metadata and that data is lost. In this case - Dell PowerVault MD3220i | Owner's Manual - Page 49

You can manually configure a host server-to-virtual disk mapping. When you configure host server-to-virtual disk mapping, consider these guidelines: • You can define one host server-to-virtual disk mapping for each virtual disk in the storage array. 50 Planning: MD3200i Series Storage Array Terms - Dell PowerVault MD3220i | Owner's Manual - Page 51
