Storage Example: AJA KONA 3 for Dual Link HD and 2K resolutions
AJA can recommend the following examples of drive configurations to support
certain specified video and digital film resolutions and their associated bandwidth
requirements. If a particular drive array or manufacturer is not listed, it may simply
be because AJA has no experience with the company or a particular unit. This guide
simply offers examples that AJA has used with success when working with the
specified formats listed. With any device, actual results may vary from unit to unit
and proper configuration of the drive array and any ancillary items such as host bus
adapters, software drivers and cabling is assumed.
Supports 2K, Dual Link HD, Single Link HD, SD:
• G-Technology, Inc. GSPEED-XL (4Gb Fibre Channel)
Unit must be fully populated and with a minimum 512MB cache per
controller.
• InforTrend EonStor A16F-G2422 (4Gb Fibre Channel)
Unit must be fully populated and with a minimum 512MB cache per
controller.
• Any drive array with comparable specifications to the above examples; 16 or
more SATA drives with 4Gb fibre channel connectivity to host and 512MB
cache per controller.
Storage capacity
No matter which storage system you choose, pick one that can scale to meet your
needs over time. Ideally, you should be able to increase storage capacity or switch to
a RAID level offering increased data protection in the future. Balance current and
future storage needs with your budget and choose accordingly.
Note: All of the following numbers are approximations based on 2 channels of
48kHz audio. More audio channels can increase data rates. AJA also provides a
freeware application called the AJA Data Rate Calculator that can be used to help
determine the amount of storage space and bandwidth requirements needed for a
selected format, frame rate, audio setting and compression. The AJA Data Rate
Calculator is also included with version 3.3 and higher of the Kona driver and can
be found in the AJA Utilities folder which installs in the Applications folder of the
Mac OS. The AJA Data Rate Calculator application can also be downloaded from
the AJA website and used on any OSX computer.
