4 VLS Devices VLS Defined The HP VLS12000 Gateway, the VLS6000-series, the VLS9000-series, and the new VLS12200 and VLS9200 are RAID disk-based SAN backup devices. All three platforms emulate physical tape libraries, allowing you to perform disk-to-virtual tape (disk-to-disk) backups using your existing backup applications. The VLS12X00 is FATA or Fibre Channel disk-based; the VLS6000-series and VLS9000-series are serial ATA disk-based, and the new VLS9200 is SAS disk-based. A multi-node VLS behaves as if it were a single device, making it easier to manage and integrate into the overall backup strategy. The VLS emulates a variety of physical tape libraries, including the tape drives and cartridges inside the libraries. You determine the number and types of tape libraries a VLS emulates, and the number and type of tape drives and cartridges included in each tape library to meet the needs of your environment. You configure the size of the virtual cartridges in your VLS, which provides even more flexibility. With no deduplication, each node on a VLS running firmware version 2.x can emulate up to 16 tape libraries and 128 tape drives. With deduplication enabled, each node on a VLS running firmware version 3.x can emulate up to 96 virtual devices (0-16 tape libraries plus tape drives). With or without deduplication, each node on a VLS12200 or VLS9200 running firmware version 6.0 or higher can emulate up to 16 tape libraries and 176 tape drives. The maximum number of virtual cartridges that can be configured on a VLS device depends on the firmware version and the VLS model: • A VLS running firmware version 1.x/2.x can create up to 8192 virtual tapes, with each array LUN adding up to a maximum of 1024 tapes capability when it is added to a storage pool (so if you upgrade later the number of tapes per LUN does not change). For example, on a VLS9000 with one 30 or 40 TB array (which contains one LUN per array enclosure and four enclosures) you can create up to 4096 tapes; if you have two or more arrays you can create 8192 tapes. On a VLS6227 (which contains one array enclosure with 750 GB disks) you can create up to 3072 tapes (with three LUNs per 750 GB array enclosure) in RAID 5 mode and up to 4096 tapes (four LUNs per 750 GB array enclosure) in RAID 6 mode. • A VLS running firmware version 3.x can create up to 32000 virtual tapes, with each array LUN adding up to a maximum of 8000 tapes capability when it is added to a storage pool (so if you upgrade later the number of tapes per LUN does not change). For example, on a VLS9000 with one or more 30 or 40 TB arrays (each full array contains one LUN per array enclosure and four enclosures) you can create up to 32000 tapes, but if you have a VLS9000 with a 10 TB array (one LUN) you can create up to 8000 tapes. On a VLS6227 (which contains one array enclosure with 750 GB disks) you can create up to 24000 tapes (with three LUNs per 750 GB array enclosure) in RAID 5 mode and up to 32000 tapes (four LUNs per 750 GB array enclosure) in RAID 6 mode. • A VLS running firmware version 6.x can create up to 64000 virtual tapes, with each array LUN adding up to a maximum of 16000 tapes capability. For example, on a VLS9200 with one 20 TB array enclosure (each 20 TB array enclosure of 12 disks contains two LUNs) you can create up to 32000 tapes, or with one 10 TB array enclosure (each 10 TB array enclosure of 12 disks contains one LUN) you can create up to 16000 tapes. VLS accommodates mixed IT-platform and backup-application environments. For more insight into mixed-IT solutions and environment analysis, visit the HP Enterprise Backup Solutions web site: http://www.hp.com/go/ebs . All of your servers and backup applications access the virtual media simultaneously. You can specify which servers are allowed to access each virtual library and tape drive you configure. You can change the default LUNs assigned to the virtual library and tape drives for each host, as needed, to accommodate different operating system requirements and restrictions. 42 VLS Devices

4 VLS Devices
VLS Defined
The HP VLS12000 Gateway, the VLS6000–series, the VLS9000–series, and the new VLS12200
and VLS9200 are RAID disk-based SAN backup devices. All three platforms emulate physical tape
libraries, allowing you to perform disk-to-virtual tape (disk-to-disk) backups using your existing
backup applications. The VLS12X00 is FATA or Fibre Channel disk-based; the VLS6000–series
and VLS9000–series are serial ATA disk-based, and the new VLS9200 is SAS disk-based. A
multi-node VLS behaves as if it were a single device, making it easier to manage and integrate
into the overall backup strategy.
The VLS emulates a variety of physical tape libraries, including the tape drives and cartridges
inside the libraries. You determine the number and types of tape libraries a VLS emulates, and the
number and type of tape drives and cartridges included in each tape library to meet the needs of
your environment. You configure the size of the virtual cartridges in your VLS, which provides even
more flexibility. With no deduplication, each node on a VLS running firmware version 2.x can
emulate up to 16 tape libraries and 128 tape drives. With deduplication enabled, each node on
a VLS running firmware version 3.x can emulate up to 96 virtual devices (0-16 tape libraries plus
tape drives). With or without deduplication, each node on a VLS12200 or VLS9200 running
firmware version 6.0 or higher can emulate up to 16 tape libraries and 176 tape drives. The
maximum number of virtual cartridges that can be configured on a VLS device depends on the
firmware version and the VLS model:
•
A VLS running firmware version 1.x/2.x can create up to 8192 virtual tapes, with each array
LUN adding up to a maximum of 1024 tapes capability when it is added to a storage pool
(so if you upgrade later the number of tapes per LUN does not change). For example, on a
VLS9000 with one 30 or 40 TB array (which contains one LUN per array enclosure and four
enclosures) you can create up to 4096 tapes; if you have two or more arrays you can create
8192 tapes. On a VLS6227 (which contains one array enclosure with 750 GB disks) you can
create up to 3072 tapes (with three LUNs per 750 GB array enclosure) in RAID 5 mode and
up to 4096 tapes (four LUNs per 750 GB array enclosure) in RAID 6 mode.
•
A VLS running firmware version 3.x can create up to 32000 virtual tapes, with each array
LUN adding up to a maximum of 8000 tapes capability when it is added to a storage pool
(so if you upgrade later the number of tapes per LUN does not change). For example, on a
VLS9000 with one or more 30 or 40 TB arrays (each full array contains one LUN per array
enclosure and four enclosures) you can create up to 32000 tapes, but if you have a VLS9000
with a 10 TB array (one LUN) you can create up to 8000 tapes. On a VLS6227 (which
contains one array enclosure with 750 GB disks) you can create up to 24000 tapes (with
three LUNs per 750 GB array enclosure) in RAID 5 mode and up to 32000 tapes (four LUNs
per 750 GB array enclosure) in RAID 6 mode.
•
A VLS running firmware version 6.x can create up to 64000 virtual tapes, with each array
LUN adding up to a maximum of 16000 tapes capability. For example, on a VLS9200 with
one 20 TB array enclosure (each 20 TB array enclosure of 12 disks contains two LUNs) you
can create up to 32000 tapes, or with one 10 TB array enclosure (each 10 TB array enclosure
of 12 disks contains one LUN) you can create up to 16000 tapes.
VLS accommodates mixed IT-platform and backup-application environments. For more insight into

All of your servers and backup applications access the virtual media simultaneously. You can
specify which servers are allowed to access each virtual library and tape drive you configure. You
can change the default LUNs assigned to the virtual library and tape drives for each host, as
needed, to accommodate different operating system requirements and restrictions.
