One should choose BLX if they have custom baremetal server , where they want to have overall control of the system and may need to install other linux based applications. One should choose a VPX if they want a ready made appliance(VM), which they want to install over a hypervisor, and want to leave the overall control of the appliance to NetScaler.
-
Yes, there will be license limitations for Management Traffic of BLX. There is no way to isolate traffic as of now. This is an interesting use case & we will surely brainstorm to support this.
-
Yes, there are few gotchas which needs to be considered. Underlying Host shouldn't use Netscaler Ports ( like 9022, 9080, 9443, etc. ) otherwise it will result in conflict.
-
Yes, we do have plans to support BLX on ARM64 in future. If support is there for BLX, ARM64 will work for CPX too.
-
Yes, we support all popular Linux Distribution in BLX. Below Link gives details of support versions of various distros - https://docs.citrix.com/en-us/citrix-adc-blx/current-release/deploy-blx.html#before-you-begin
-
Yes, BLX supports Pooled Licensing. There is no License limitation for BLX.

Can you cluster a NetScaler BLX?
Nagesh Mallappa replied to Harihara Sudhan's topic in Core ADC use cases
Yes, we do support Cluster (both L2& L3 ) in BLX. -
No, there is no difference. It is exactly same ns.conf which is used in all Netscaler form factors.
-
Does BLX have GUI support as VPX & MPX?
Nagesh Mallappa replied to Harihara Sudhan's topic in Core ADC use cases
Yes GUI-Support is there on BLX which is exactly same as VPX & MPX. -
Linux Firewall need not be disabled to run BLX. BLX open some ports and have ip table rules which gets activated during BLX bring up. Below Link helps to run BLX with SE-linux enabled - https://community.netscaler.com/s/question/0D58b0000AYZo5LCQT/it-is-possible-to-run-netscaler-adc-blx-when-the-host-linux-selinux-is-configured-to-be-enforcing-
-
Yes, we already have a POC for this solution , but there is no active development activity at the moment.
-
Yes, BLX can be deployed on an Linux based Virtual Machine. There is no difference in BLX Bring up, Start and Functioning.
-
No, we do not have plans to add BLX packages in public repositories ( like apt, yum) in short-term.
-
As of now, BLX supports Software based SSL offload acceleration. Exploration is going on to support Hardware based SSL acceleration, we hope to deliver it soon in future releases.
-
Yes, there is a limitation on number of Nic Interfaces / Ports that can be dedicated to Netscaler BLX. As of now we can dedicate upto 8 Interfaces on both DPDK & Non-DPDK based BLX. In future releases we hope to increase the number of Interfaces that can be dedicated to BLX.
