For information on using the remote replication features in HP P6000 Command View, see the HP P6000 Continuous Access Implementation Guide. This chapter focuses on using the local replication features in HP P6000 Command View. Replicated virtual disks are located on a different storage system than the source, typically at a geographically separate site. HP P6000 Continuous Access (remote replication).Replicated virtual disks are located on the same storage system as the source. Make local copies of virtual disks using snapclones, snapshots, mirrorclones and preallocated containers. HP P6000 Business Copy (local replication).With HP P6000/EVA storage systems, entire virtual disks can be replicated locally or remotely using a variety of methods: A physical volume corresponds to a single disk device.Ī virtual storage unit created by mapping data from one or more logical disks.Replication is an industry-standard term for making copies or backing up data. For a host to see a virtual volume, the volume must be exported as a LUN by creating vLUNs on the storage array.Įquivalent to what other storage array vendors call a LUN.Ī logical entity that holds user data that is accessible through one or more of the access protocols supported by Data ONTAP, including Network File System (NFS), Common Internet File System (CIFS), HyperText Transfer Protocol (HTTP), Fibre Channel (FC), and Internet SCSI (iSCSI).Ī general term referring to a storage device. (volume-LUN) A pairing between a virtual volume and a logical unit number (LUN). The Data ONTAP documentation uses the term array LUN to distinguish LUNs on the storage arrays from front-end LUNs (Data ONTAP LUNs).

Presenting a virtual disk offers its storage to a host.ĭata ONTAP documentation, Data ONTAP storage management tools You can assign a combination of characteristics to a virtual disk, such as a name, redundancy level, and size. Clients are unaware of where a front-end LUN is stored.Ī virtual disk (called a Vdisk in the user interface) is a simulated disk drive created in a disk group. The Data ONTAP system can virtualize the storage attached to it and serve the storage up as LUNs to external applications and clients (for example, through iSCSI and FC). In the Data ONTAP documentation, this is referred to as array LUN. Hardware on the storage array on which the target ports are located.Ī grouping of one or more disks or disk partitions into one span of disk storage space. Controllers are also sometimes called heads or CPU modules.

The component of a storage system that runs the Data ONTAP operating system and interacts with back-end storage arrays. In clustered Data ONTAP 8.x, a grouping of nodes that enables multiple nodes to pool their resources into a large virtual server and to distribute work across the cluster.Ī hardware component on the storage arrays that contains the ports to which hosts attach.Īn entity that groups multiple hosts together and assigns the same mapping to all the hosts. (A chunklet is a 256-MB block of contiguous space on a physical disk.) The arrangement of disks in the back-end that together form the defined RAID level.Ī DMX feature that provides parity data protection on the disk device level using physical parity volumes.Ī set of physical disks that form storage pools from which you can create virtual disks.Ī group of parity-protected chunklets. You must create a host in the ESS user interface for each FC initiator port that you plan to connect to the storage array and map each host to a port. You identify the FC initiator port WWNs for the Data ONTAP system that you want to access the LUNs the process differs according to vendor and sometimes differs for different storage array models of the same vendor.įujitsu ETERNUS4000, ETERNUS6000, ETERNUS8000, ETERNUS DX8000, ETERNUS DX400 A configuration entity that enables you to specify host access to ports on the storage array.
