34 Planning: RAID Controller Modules RAID Controller Modu le—Additional Features Battery Backup Unit Each R AID controller contains a two- cell Lithium ion nanopolymer battery backup unit (BBU). It provides power to the R AID controller module in the event of a powe r outage.
Planning: RAID Controller Modules 35 Storage Array Thermal Sh utd own The system automatically shuts down when system tem perature e xceeds the safe threshold. The battery backup unit protects against data loss by providing power to offload cache to no n-volatile memory in the event of power loss.
36 Planning: RAID Controller Modules Cache Functions and Features Cache Mirroring Cache mirroring function co pies accepted host-write data from the pri m ary controller to the partner controller . This action ensures that host-write data is safely mirrored to the partner cont roller before successful completion status is returned to the host.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 37 4 Planning: MD3200 Series Storage Array T erms and Concepts This chapter e xplains the terms and concepts used for configuration and operation of the MD3200 Series storage arrays.
38 Planning: MD3200 Series St orage Array T erms and Concepts Phy sical Disks Only Dell supported 6.0-Gbps SAS physica l disks are supporte d in the storage array . If the storage array detects unsuppo rted physical disks, it marks the disk as unsupported and the physical disk be comes unavailable for all operations.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 39 If a disk drive rebuild fails because of a source drive failur e or because the drive is too small, the MDSM r eports a failure of the ph.
40 Planning: MD3200 Series St orage Array T erms and Concepts 3 P rovide host server access. 4 Create mappings to associate the vi rtual di sk s with the host serv ers . NOTE: Host server access must be cr eated before mapping virtual disks. Disk groups are always created in the un configured capacity of a storage arra y .
Planning: MD3200 Series St orage Ar ray T erms and Concepts 41 Using multiple physical disks has the follo wing advantages over usi ng a sing le physical disk: • Placing data on multiple physical disk s (striping) allows input/output (I/O) operations to occur simultaneo usly and improve performance.
42 Planning: MD3200 Series St orage Array T erms and Concepts RAID 1 RA ID 1 uses disk mirroring so that da ta written to one physical disk is simultaneously written to another physica l disk. This RAID level offers fast performance, the best data availability , and the highest disk over head.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 43 Segment Size Disk striping enables data to be wri tten across multiple physical disks. Disk striping enhances performance be cause striped disks are accessed simultaneously . The segment size or stripe element s ize specifies the size of data in a stripe written to a single disk.
44 Planning: MD3200 Series St orage Array T erms and Concepts Consistency Check A consistency check verifies the corr ectness of data in a r edundant array (R AID levels 1, 5, 6, and 10).
Planning: MD3200 Series St orage Ar ray T erms and Concepts 45 Virtual Di sk Operations Limit The maximum number of active, concurre nt virtual disk processes per R AID controller module installed in the storage array is four .
46 Planning: MD3200 Series St orage Array T erms and Concepts Dynamic segme nt size migration enables the segmen t size of a given virtual disk to be changed. A default segment size is set when the virtual disk is created, based on such factors as the RAID level and expected usage.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 47 Disk Group Defragmentation Defragmenting consolida tes the free ca pacity in the disk group into one contiguous area. Defragment ation does not change the way in which the data is stored on the virtual disks.
48 Planning: MD3200 Series St orage Array T erms and Concepts • Segment size migration • Disk group expansion • Disk group defragmentation The priority of each of these operat ion s can be changed to address performance requirements of the environment in whi ch the operations are to be e xecut ed.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 49 the MD3200 Series storage array does not recognize the migrating metadata and that data is lost. In this case, th e MD3200 Series storag e array initializes the physical disks and marks them as unconfigured capacity .
50 Planning: MD3200 Series St orage Array T erms and Concepts • Migrating virtual disks to a storage array with no existing physical disks— T ur n off the destination storage array , when migrating disk groups or a complete set of physical disks from a storage arra y to another storage array that has no existing physical disks.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 51 Host Server -to-V irtual Disk Mapping The host server attached to a storage array accesses various virtual disks on the storage array through its host ports. Specific virtual disk-to-L UN mappings to an individual host server can be defined.
52 Planning: MD3200 Series St orage Array T erms and Concepts online and user -accessible. When the backup is completed, the snapshot virtual disk is no longer needed. Y o u can create up to four snapshots per virtual disk. Snapshots ar e used to r eco ver previo us versions of files that have changed since the snap shot was tak en.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 53 Vi rtual Disk Copy Virtual disk copy is a pr emium feature to : •B a c k u p d a t a • Copy data from disk groups that use sm aller -capacity physical disks to disk groups using greater capacity physical disks • Restore snapshot virtual disk data to the source virtual disk.
54 Planning: MD3200 Series St orage Array T erms and Concepts Virtual Disk Recovery Y ou can use the Edit host server-to- virtual disk mappings featur e to recover data from the backup virtual disk.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 55 The multi-path software identifies the ex istence of multiple paths to a virtual disk and establishes a pr eferred path to that disk.
56 Planning: MD3200 Series St orage Array T erms and Concepts Ownership can later be mo dified to balance worklo ad according to a ctual usage. If virtual disk ownership is not manually balanced, it is possible for one controller to have the majority of the work, while the other controller is idl e.
Planning: MD3200 Series St orage Ar ray T erms and Concepts 57 • Le ast path weight with s ubset (W indows operating systems only)—The least queue depth with subset policy is also known as the le ast I/Os or least requests policy . Thi s policy routes the next I/O r equest to a data path that has the least outstanding I/O requests queued.
