Product Overview
28 NAS e7000 v2 Quick Start Guide
Storage Elements
The lowest level of storage management on the NAS e7000 v2 occurs at the
physical drive level. Physical drives are grouped into RAID arrays for fault
tolerance and better performance. Configure RAID arrays using the appropriate
storage configuration tool for the SAN in use or request that the SAN
administrator establish the appropriate LUNs.
Logical Storage Elements
Single Server Implementations
Logical Storage elements consist of those components that translate the physical
storage elements to the file system elements as presented in
Figure 5 . The
e7000 v2 utilizes the Microsoft Logical Disk Manager (LDM) for managing the
various types of disk presented to the file system. LDM has two types of LUN
presentation, basic disk and dynamic disk. Each of these types of disk has special
features that enable different types of management. Through the use of basic
disks, partitions or extended partitions may be created. Partitions can only
encompass one LUN up to 2 TB in size. By using dynamic disks, you can create
volumes that span multiple 2 TB LUNs up to 64 TB in total volume size. Volumes
or partitions can then be assigned a drive letter or mount point, formatted, and
then presented to the operating system for use.
Clustered Server Implementations
Clustered implementations differ from single server implementations in that they
can only utilize basic disks. Basic disks are the subcomponent of physical disk
resources that can then be used as basic units of failover in a cluster. All basic
disks should have an assigned drive letter since mount points are not supported in
Microsoft clustering.
File System Elements
File system elements are composed of the folders and subfolders that are created
under each logical storage element (partitions, logical disks, and volumes).
Folders are used to further subdivide the available file system providing another
level of granularity for management of the information space. Each of these
folders can contain separate permissions and share names that can be used for
network access. Folders can be created for individual users, groups, projects, and
so on. Refer to the administration guide for more details on file system elements.
