The following existing models will support cOS Core 14.00
- Clavister NetWall E10
- Clavister NetWall E20
- Clavister NetWall E80
- Clavister NetWall W20
- Clavister NetWall W30
- Clavister NetWall W40
- Clavister NetWall W50
- Virtual Appliances running the 32-bit image (VMware, Hyper-V, KVM).

- Clavister NetWall 110
- Clavister NetWall 140
- Clavister NetWall 510
- Clavister NetWall 550
- Clavister NetWall 6200
- Clavister NetWall 6600
- Virtual Appliances running the 64-bit image (VMware, KVM).
Any appliance that is released after the release of cOS Core 14.00 will ONLY support cOS Core 14.00 or later.
Why will the new appliances only support cOS Core 14.00?
The new appliances will use a 64-bit version of cOS Core, this version is not possible to to downgrade to older versions as they are only available in 32-bit versions.
Is it difficult to upgrade from cOS Core 13.00 to 14.00?
No, it’s done in the same way as from 12.00 to 13.00 or upgrading from cOS Core 13.00.07 to 13.00.08. Remember to read the release notes for any version specific information.
Can the E or W-series appliances be upgraded to the 64-bit version of cOS Core 14.00?
No, appliances running the 32-bit firmware will not be possible to upgrade to the 64-bit version of cOS Core, also there is no real benefit as the E and W-series appliances are optimized for the 32-bit firmware.
What is the benefit of moving to 64-bit on the new appliances?
There are a number of benefits, mainly the possibility to use more memory, but also leverage new hardware features that is not available when using 32-bit.
Will there be differences between 32-bit and 64-bit cOS Core 14.00?
There is no visible difference between the two versions, except that the 64-bit version will be able to use more memory. Over a longer time period there might be diverging feature set on old appliances (running 32-bit) and new appliances (running 64-bit), where some features requiring 64-bit processing will only be available on newer appliances. But as long as possible Clavister will try to keep feature parity. There was a similar situtaion with cOS Core 12.00 where some features did not work on IXP-based platforms (Clavister E5 and E7) due to hardware limitations.
Is it complex to migrate from from a 32-bit appliances to a 64-bit appliance?
No, it’s not complex at all, it’s as easy as it was upgrading from Clavister E7 to Clavister NetWall E80.
Is the 64-bit version based on Linux?
From 14.00, cOS Core is using Linux as a boot loader when running 64-bit, Linux is used for memory management, file system access, etc, (same functions is provided by “Firewall Loader/FWLDr” in 32-bit cOS Core). The Clavister cOS Core is still directly using the network cards so no network traffic can reach the Linux subsystem.
