Next generation virtualization capabilities that dynamically provision resources such as storage logical unit numbers (LUN) over distributed arrays or migrate live compute instances between buildings with tools like VMware's VMotion become possible when an enterprise has a high-capacity, low-latency interconnect such as Matisse Network's EtherBurst.
To place some order on the incipient chaos, SANs use unique identifiers called logical unit numbers (LUNs).
With this announcement, the S2100-ES2 will provide support for IBM 3592 drive and 3584 library emulations and up to 192 virtual Logical Unit Numbers (LUNs) of any mix of tape drives and libraries per node for a maximum of 1536 in a single VTL appliance.
Administrators manage virtual logical unit numbers (LUNs) associated with servers or applications instead of specific physical arrays and drives:
In addition to offering support for up to 64TB per array or logical drive (LD), Rorke Data's new firmware suite allows access up to 1024 host logical unit numbers (LUNs) and 64 partitions per LD.
In addition to breaking the 2TB barrier with support for up to 64TB per array or logical drive (LD), Infortrend's new firmware allows access up to 1024 host logical unit numbers (LUNs) and 64 partitions per LD.
The industry will benefit from having a standard, nonproprietary way of accessing storage and SAN-device information as well as having a common model for activities such as masking logical unit numbers.
256 volumes per partition -- allows the storage system to present up to 256 host-addressable Logical Unit Numbers (LUNs) to a given host port to provide support for large databases, greater connectivity and capacity for SAN environments and more room for snapshot and clone volumes.
The Virtual Disk service enables easy detection, configuration, and management of logical unit numbers (LUNs), providing a common interface for LUN management and enabling applications to configure virtual disks to their needs.
Imperial's administration toolset simplifies partitioning the File Cache Accelerator into as many as 64 Logical Unit Numbers (LUNs), making each LUN appear as a disk drive residing in the SAN.
