Terms and Concepts This chapter explains terms and concepts used for configuration and operation of MD3200 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 MD3200 | Owner's Manual - Page 36
Physical Disks Only Dell™ supported 6.0-Gbps SAS physical disks are supported in the storage array. If the storage array detects unsupported physical disks, it marks the disk as unsupported and the physical disk becomes unavailable for all operations. NOTE: The MD3200 Series array must contain at - Dell PowerVault MD3200 | Owner's Manual - Page 37
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: 1 Organize the physical disks into disk groups. 2 Create virtual disks within these disk groups. Planning: MD3200 Series Storage Array - Dell PowerVault MD3200 | Owner's Manual - Page 38
of physical disks are available to support the virtual disk. RAID Levels RAID levels determine the way in which data is written to physical disks. Different RAID levels provide different levels of accessibility, redundancy, and capacity. 38 Planning: MD3200 Series Storage Array Terms and Concepts - Dell PowerVault MD3200 | Owner's Manual - Page 39
provides different performance and protection. You should select a RAID level based on the type of application, access, fault tolerance, and data you are storing. The storage array supports RAID any application requiring high bandwidth. Planning: MD3200 Series Storage Array Terms and Concepts 39 - Dell PowerVault MD3200 | Owner's Manual - Page 40
RAID 10, a combination of RAID 1 and RAID 0, uses disk striping across mirrored disks. It provides high data throughput and complete data redundancy. Utilizing an even number of physical disks (four or more) moderate-to-medium capacity. 40 Planning: MD3200 Series Storage Array Terms and Concepts - Dell PowerVault MD3200 | Owner's Manual - Page 41

Background Initialization The storage array executes a background initialization when the virtual disk is - Dell PowerVault MD3200 | Owner's Manual - Page 42
on the disk group, the storage array resumes after the current cycle. If the media verification process on a disk group is stopped due to a RAID controller module restart, the storage array resumes the process from the last checkpoint. 42 Planning: MD3200 Series Storage Array Terms and Concepts - Dell PowerVault MD3200 | Owner's Manual - Page 43
to a RAID 5 set. MDSM provides information about RAID attributes to assist storage array writes on a single physical disk in a virtual disk before writing data on the next physical disk. Valid values for the segment size are 8, 16, 32, 64, 128, 256, and 512 KB. Planning: MD3200 Series Storage Array - Dell PowerVault MD3200 | Owner's Manual - Page 44
and increased unused free space are dynamically redistributed across the disk group. RAID characteristics are also reapplied to the disk group as a whole. 44 Planning: MD3200 Series Storage Array Terms and Concepts - Dell PowerVault MD3200 | Owner's Manual - Page 45
. RAID Background Operations Priority The storage array supports a common configurable priority for the following RAID operations: • Background initialization • Rebuild • Copy back • Virtual disk capacity expansion • Raid level migration Planning: MD3200 Series Storage Array Terms and Concepts 45 - Dell PowerVault MD3200 | Owner's Manual - Page 46
from one MD3200 array to another, the MD3200 array you migrate to, recognizes any data structures and/or metadata you had in place on the migrating MD3200 array. However, if you are migrating from any device other than a MD3200 Series Storage Array, 46 Planning: MD3200 Series Storage Array Terms - Dell PowerVault MD3200 | Owner's Manual - Page 47
migrated to the destination storage array before starting migration from the next storage array. NOTE: If the drive modules are not moved as a set to the destination storage array, the newly relocated disk groups might not be accessible.

Disk Snapshot, Virtual Disk Copy, and High Performance Tier are premium features that must be activated separately. If you have purchased these features, an activation card is supplied that contains instructions for enabling this functionality. 48 Planning: MD3200 Series Storage Array Terms - Dell PowerVault MD3200 | Owner's Manual - Page 49
. The snapshot provides an image of the virtual disk at the time the snapshot was created. You create a snapshot so that an application (for example, a backup application) can access the snapshot and read the data while the source virtual disk remains Planning: MD3200 Series Storage Array Terms and - Dell PowerVault MD3200 | Owner's Manual - Page 50
or an inaccessible snapshot. For details on mapping the snapshot virtual disk to the secondary node, refer to the Dell™ PowerVault™ MD3200 and MD3220 Storage Arrays With Microsoft® Windows Server® Failover Clusters on support.dell.com/manuals. 50 Planning: MD3200 Series Storage Array Terms and - Dell PowerVault MD3200 | Owner's Manual - Page 51
