Capacity Licensing; Base Capacity License By Vls Model; Adding Capacity Beyond The Base Configuration - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

• Set the tape block size to 256 KB for all VLS tape drives.
• Disable multiplexing/interleaving on all backup jobs to the VLS.
• Identify clients on the SAN that are currently performing LAN-based backup but could be converted
to LAN-free backup to improve performance. See
• Determine if there are performance bottlenecks in the current backup (e.g., LAN or SAN ISL bot-
tlenecks) that you must resolve to allow full performance to the VLS.
• Based on your offsite copy requirements, assess the configuration changes needed to implement
offsite copy. See
• Copying through the backup application means creating copy jobs, ensuring there are good
copy paths between the virtual library and the physical library on the SAN (e.g., plug into
same switch), etc.
• Copying with automigration means the system needs no changes to the backup application.
• Copying with replication (deduplication-enabled) means the system needs no changes to the
local backup application, but if there is a separate backup application at the target device
this may require setting up an import script.

Capacity Licensing

The VLS devices are licensed by their usable disk capacity (in terms of array LUNs). Each VLS has an
embedded "base capacity" that varies depending on the VLS model:
Table 22 Base Capacity License by VLS Model
VLS model
VLS6218, 500 GB
drives
VLS6218, 750 GB
drives
VLS6636, 500 GB
drives
VLS6653, 750 GB
drives
VLS9000–series
VLS12000–series
If capacity is added to the VLS beyond the above base license level, you must install capacity upgrade
licenses (which you can install via the VLS GUI). There is a different upgrade license for each VLS
range:

Covers the one MSA20 disk array enclosure that comes bundled.

Each node adds a base license for one full VLS9000 array (48 drives, 30 TB or 40 TB).
The entry-level VLS9000 7.5 and 10 TB systems do not need additional licenses to add
capacity kits up to the full array configuration.
Each node adds a base license for 10 EVA LUNs. The base 2-node VLS12000 kit in-
cludes a 5-LUN upgrade license giving a total license of 25 LUNs of up to 2 TB each.
Capacity upgrade license
Enables an additional MSA20 array with 250/500 GB drives or half an MSA20 array
with 750/1000 GB drives per license (so you need two licenses to add an MSA20
array with 750/1000 GB drives).
