HP 12000 Virtual Library System EVA Gateway - Manual (Page 12)

Up to six nodes can be added to a Gateway for a total of eight nodes in a single Gateway. You
can increase capacity by purchasing capacity licenses, each of which adds licensing for one
additional external array LUN and increases maximum external capacity by up to 2 TB.
Adding nodes and licenses increases the Gateway storage capacity as shown in Table 1 (page
12) . Adding nodes also increases the performance. See the HP StorageWorks VLS12200 Virtual
Library System Quickspec on the HP web site ( http://h18006.www1.hp.com/storage/disk_storage/
disk_to_disk/vls/vls_gateway/index.html ) for performance data.
