ArubaOS simulator?

HPE put some effort into Comware training. Creating books for HPE Press and releasing a Comware simulator. Now that HPE has all but dropped Comware it's back to square one. There's a general lack of training materials compared to Cisco or Juniper.

 

Will we ever see a new simulation envrioment like the Comware simulaor (now developed by New H3C) or Cisco's Packet Tracer? Cisco is now so far ahead of HPE/Aruba when it comes to training that's it's not even funny.

Seriously?

I suspect you were wrongly informed about that (Comware 5 and 7 operating systems are still alive and kicking, especially Comware 7).

Re: ArubaOS simulator?

Comware7 is alive and well only because of New H3C. Don't think HPE is putting any effort into it anymore. In the access layer and in mid-size core it is certainly dead for HPE.

I'm not totally sure about that...HPE divested its H3C assets in favour of Tsinghua in China back in mid 2015 but that event didnt't mean that existing and potential new DC oriented customers will not be able to find - actually - a suitable Comware 7 (and 5 too) products well documented abd  kept up-to-date (and that, for HPE, means that their R&D+Support Teams put a lot of efforts).

 

OTOH DC requirements are quite different from Campus/Access ones...so new features, if any, appear slowly...also consider that Comware 7 is already a full-featured operating system and it has a very long heritage, given that it is positioned to run on Core and ToR Switch series...at DC robustness and service continuity win against new features and frequent releases (in Campus/Access we're used to see a lot of new features and a lot of software releases - or a short development cycle - instead).

Access and Campus core are now covered by Aruba Switch series because HPE decided that way after Aruba acquisition, yes that's true...but that doesn't mean that you can't purchase an HPE FlexNetwork 5510 and live well exactly as you do if you purchase an Aruba 3810M. Both are good (with pros/cons).

 

Probably Aruba direct/indirect sales and Aruba Partners have a mission: to push and sell Aruba products portfolio only...hiding the fact that HPE FlexNetwork product portfolio has (few) products still capable to go down up to the "access layer" (with PoE and all the bells&whistles)...and (more) products capable to stay at the core of any DC, globally. That's marketing IMHO.

Re: ArubaOS simulator?

There is a ArubaOS-CX simulator (actually for HPE and Partners...)

 

and it is complicated (impossible) to have a ArubaOS (ex Procuvre) Simulator (Because it is a specific hardware stuff...)






PowerArubaSW: Powershell Module to use Aruba Switch API for Vlan, VlanPorts, LACP, LLDP... More info

PowerArubaCP: Powershell Module to use ClearPass API (create NAD, Guest...) More info

PowerArubaCX: Powershell Module to use ArubaCX API (get interface/vlan/ports info)

Yeah, that simulator is the ArubaOS-CX Open Virtual Appliance (abbreviated ArubaOS-CX OVA), actually aligned with latest ArubaOS-CX 10.01.0020 software relase.

That's quite reasonable...probably because Comware 5/7 operating system based switch series (3Com/H3C/HPE) use (best-of-breeze) merchant silicon while HP ProCurve, historically, used (and still uses) customized ASIC (the HP ProVision which gave the name to the operating system)...so virtualizing HP ProVision operating system based switch series is not exactly like doing the same that was done for Comware based devices by H3C (indeed they were able to release to the public the H3C Cloud Lab image).

 

Probably an ArubaOS-Switch "simulator" (or virtual environment) does exist but it's for very internal usage only by development.

The main issue I have with that is that due to change of direction there's actually a complete mess of products. Airwave and Central are useless for anything running on Comware 7. IMC lacks proper support for Aruba wireless. ClearPass is very well supported out-of-box for Provision/ArubaOS but not for Comware. I would at least like to see a similar level of intergation with ClearPass on Comware 7 as is supported on ArubaOS.

 

Also Comware has always been a much better platform and hardware running on it has always been more reliable than anything Provision based, so it's a bit sad that Provision is getting a preferential treatment.

 

At this point I would be wary of buying any more Comware based equipment. The fact is that switching to ArubaOS as a main platform only a couple of years later after telling everyone to invest into Comware, is an unwelcome move.

I don't think there's any need to emualte the harware side. Of course it would mean that direct porting would be impossible. What's needed is a simualtion of the interface itself. Cisco Packet Tracer is also not a direct port of Ciscos IOS but it's a great learing tool. It's used by pretty much every IT school here. It's very easy to find someone who can manage Cisco network.


The fact is that Cisco has very good learing tools available. The wealth of materials, learing institutions offering Cisco courses, web training by companies like CBT Nuggets, virtual labs and so on is overwhelming. HPE at least made some effort with Comware Lab, but now that Comware is out of the picture HPE/Aruba has nothing to compete with Cisco (or even Juniper) in this regard.

If you want to emulate an Hardware (x86, RISC, ...whatever) you need to trying a way to virtualize it using an Hardware Abstraction Level which is an additional software level...or not?

 

To simulate a UI (Graphical, CLI based...whatever) you need to let the system in which the simulation software is running to believe to run over the hardware that that very GUI or CLI is effective and produces its effects...or not?

The latter is not neccesarily true. One can emualte the GUI without the underlying hardware. It would be just more work.

 

But that is all beside the point. The point is that Cisco (and Juniper and New H3C) have learning/simualtion environments and virtual labs available (with Cisco having a huge edge here) and Aruba/HPE does not.
