In November 2017, Avid announced that they would be discontinuing the Avid NEXIS | Pro 20TB engine, and replacing it with the 40TB model they had premiered at IBC. With stocks of the 20TB model now critically low, we looked at the key questions you need to ask before moving to the 40TB engine.
Will my existing 20TB engines still be supported?
Yes. Avid will provide support for any 20TB NEXIS | Pro covered by a support contract until 31st December 2022, so your hardware should be safe for the rest of its usable life. It will continue to qualify for maintenance software releases, including bug fixes and client OS compatibility updates.
Will I be able to continue using my existing hardware?
Again, yes. See below for specific compatibility information.
How does the price compare to the existing 20 TB engine?
The new, larger engine is actually better value per TB, offering you twice the storage capacity for a relatively small uptick in price (the base model of the 40TB unit is currently £1000 more than the base 20TB model).
Are there limits to how I can configure my NEXIS | Pro system?
Essentially, the same limits apply to NEXIS systems built from the new storage model as follows:
– Up to four Media Packs (in this case up to four engines) can be merged into one NEXIS | Pro system which uses the embedded System Director service mode of NEXIS File System.
– Up to 30 clients can be connected to the NEXIS Pro storage system simultaneously.
– Up to 24 clients can be actively connected to the system accessing storage Workspaces simultaneously.
– NEXIS Pro Engine Media Packs can be bound to the file system in either Scale Out Storage Group (SOSG) mode or in High Performance Storage Group (HPSG) mode. For systems containing more than one engine, both modes can be used (starting, perhaps, with one Media Pack in SOSG mode and one Media Pack in HPSG mode), and up to four Storage Groups can be configured as follows:
– Up to four engines can be connected and from one to four Storage Groups can be created with each engine’s Media Pack bound to the file system in SOSG mode delivering up to 400 MB/s bandwidth per Media Pack. Storage Groups can be sized according to bandwidth requirements, and further Media Packs added later if expansion is required (subject to the four Media Pack system limit).
– Up to four engines can be connected and one Storage Group can be created with each engine’s Media Pack bound to the file system in HPSG mode delivering up to 600 MB/s bandwidth per Media Pack bound in this mode. Additional Storage Groups can also be created if required; however, these must use SOSG bound Media Packs.
Can NEXIS | Pro engines be mixed with NEXIS | E ones?
NEXIS | Pro storage cannot be mixed with NEXIS | E series engines, although a NEXIS | Pro based system and one or more NEXIS | E series based systems could be run in the same network environment if required, and from a common client base.
Can I add NEXIS | Pro 40TB Engines to my NEXIS | Pro 20TB system?
Yes, you can do this safely, although the total number of NEXIS engines in a NEXIS Pro engine-based NEXIS system cannot exceed four, and you will need to be running at least NEXIS software v7.10.1. This may mean that a software update must be performed on the existing NEXIS | Pro 20TB engines and all clients accessing the storage prior to adding the new NEXIS engines to the system.
Ideally, NEXIS | Pro 40TB Engines would be added to a new Storage Group separate from any existing Storage Groups consisting of NEXIS | Pro 20TB Engines in order to optimise available storage capacity.
Can I add NEXIS | Pro 40TB Engines to my ISIS 1000 system?
Yes, although the ISIS 1000 system would need to be upgraded to NEXIS | Pro 20TB engines and NEXIS v7.10.1 software or above before the new storage was added.
Can I add NEXIS | Pro 40TB Engines to my ISIS 5000 system?
No. However, NEXIS systems can be run safely alongside an ISIS system and both storage systems can be accessed from a common Avid Shared Storage client. So if you need to expand your available storage capacity or increase the storage bandwidth available to clients, a suitably configured Avid NEXIS system can be established in the same network as your existing ISIS system. In this case the ISIS system must be running a minimum version of ISIS v4.7.5 software (although the latest v4.7.11 is highly recommended) and the existing ISIS client software can be updated to the Avid NEXIS client software.
What level of storage protection is offered by NEXIS | Pro series engines?
Administrators can select to have data protected in NEXIS | Pro based file systems with either One Disk or Two Disk protected Workspaces. In the case of the One Disk protected Workspaces, data located in these Workspaces will remain available to users in the case of one disk in the NEXIS Media Pack failing. In the case of the Two Disk protected Workspaces, data located in these Workspaces will remain available to users in the case of up to two disks in the NEXIS Media Pack failing. Administrators can also elect to create Workspaces with no data protection enabled, although we recommend that users only select this option if they have an effective onsite backup workflow in place.
Is NEXIS engine mirroring available as a data protection scheme in NEXIS | Pro based systems?
No, this advanced data protection scheme requires use of the NEXIS System Director Appliance (SDA) and is only available in NEXIS |E Series engine-based configurations.
