2.0.1 is ready for production.
Please leave feedback if you find any issues so we can investigate and if needed fix asap. Note: No backward compatibility.
Packet Loss Recovery and Packet Order Correction features are available for very early testing.

Wanos Update
UPDATED: Link to Wanos Update (http://wanos.co/docs/docs/wanos-admin-guide/configuration/software-update/)
2.0.2
It has a major throughput performance boost on recent CPU/RAM hardware. Depending on hardware configuration throughput increase is expected to be 20-130%. On one specific test system throughput increased 2.3X.
Additional safety checks for packet loss recovery and packet order correction. These features are very robust and dynamic based on network conditions. Cold compression ratio increase significantly with these enabled (will get the specific figures). Link to guide -> UPDATED: Packet Loss Recovery (http://wanos.co/docs/docs/wanos-admin-guide/configuration/packet-loss-recovery/)
Some reported missing peer status info in the Peerstatus tab at random times.
MultiSite calculated required Ram incorrectly.
Added initial Health Status/Check tab.
SSH disabled/enabled via gui settings
Datastore drive configurable via GUI. (Still requires valid partition to exist). After updating to 2.0.2 double check / reconfigure datastore drive.
As requested the policy configuration has been made easier to edit existing rules.
-
Fantastic! I will get this loaded up on my home ESXi server and report back, probably this weekend.
-
Hi Antonie,
Are there any new features added to this version? You have indicated some elements have been recoded. What are the improvements if any?
-
Awesome, thanks Jeremy. It would be great to see if you see any speed improvements or in the unlikely worst case, a degradation.
-
Hi Mark,
The change log is quite long but here are the key points:
General:
Linux kernel and modules were updated to more recent versions. This was needed to run on more recent top end servers.
We have bumped the click version to the latest.
Compression Engine:
The code was rewritten from scratch. All in all this was a risky change, but I think the benefit is going to be huge. On one client submitted replication sample of about 1.5GB, the reduction increased from 3.3X to 5.7X. We are optimistically hopeful that the change will make the Wanos cold compression very close to the likes of Silver-Peak and Riverbed. At least definitely on some types of data. We have also made the compression level configurable.
The figure above depends on the packet loss recovery and packet order correction, which is in alpha stage. It works perfectly in the lab, but needs some final refinement to be perfectly robust in production. We can enable this from the command line if your team is interested in testing. I am hoping that we can get this feature in an early beta stage for 2.0.1 in two weeks time.
Encapsulation:
Due to the some changes in Cisco IPsec VPN's dropping IPComp traffic without a trace, we have added optional GRE encapsulation and made the UDP encap which has proven useful, available in the GUI. Also the UDPEncap has been changed to provide IP layer transparency so that this feature is compatible with WANs with ACL filters based on the client/server ip addresses.
GUI:
Some minor improvements in the GUI has been made. The most important one is that WAN Rx stats is now also available, where previously only Tx info was available.
The optimization graphs has also been changed to make it easier to see the optimization difference between LAN and WAN.
Added appliance shutdown option
Time settings.
Gui bugs fixed:
Missing mask on destination subnet in a traffic policy.
Invalid gateway address validation check.
Multithreading:
Some changes were made to improve on the dedup multithreading in a multisite context.
Disk IO:
Dedup improvements in disk IO that made a 10-15% increase in TCP throughput.
What we are in the process of completing or integrating:
Another level of improved compression ratio.
Packet loss recovery - Fail safe methods.
WAN Health indicators: RTT, Packet loss and Out of order.
Out of path via PBR
HTTP Cache.
Short term wishlist:
Single NIC bridge for devices like the Intel NUC. E.g. to bridge two vlans on a single trunk interface.
Out of path tunnel mode for simpler cloud deployments.
-
Also
Console: By default console login is enabled on com1 with baud rate of 9600. The wanos 200 appliance uses a normal Cisco console cable and console settings.
-
Hi Antonie,
Thanks for the information. Console access can be invaluable.
-
Version 2.0.1.
It is a minor update from 2.0.0:
Updated drivers for SCSI Drives and Broadcom bnx2 based NIC's
Show Tech tab added to export configs and logs to help with remote support
More safety checks added to packetloss recovery in preparation for beta
Disabled GUI access on http port 80
Minor cosmetic fixes: dropdown options, system time in overview
Initial wanos-fdisk utility

how do I upgrade from prev version 1.4.1 to new version ?, installation from scratch or some update process available ? if not how do I take backup of policies from 1.4.1 & restore back later after 2.0.1 installation.
-
Hi Anil,
Installation from scratch is the only option right now. Once we get enough data to determine that it is stable for production use, we will create the upgrade script. The update will upgrade 1.4.1 to 2.0.x while keeping IP addresses, policies, multisite configs etc.
-
Hi,
if scratch, how do I export & import policies ?
I have at least 20 line entries in traffic polices.
-
If you want to go ahead with 2.0.1 in production, then copy /tce/etc/wanos/policies over to the new system. If you have multisite then the peersites file as well. This is what the update script will do.
-
If I upgrade to 2.0.1 will it talk to the older versions correctly or do all sites need to be on the same version?
-
Unfortunately this major update is not compatible with <= 1.4.1
-
Any updates on where V2 is at?
-
Hi Mark,
v.2.0.2 will be a minor update with update script. It will be possible to update from 1.4.1 to 2.0.2 from the cli.
Release should be out on Monday. It has a major throughput performance boost on recent CPU/RAM hardware. Depending on hardware configuration throughput increase is expected to be 20-130%.
Additional safety checks for packet loss recovery and packet order correction. Cold compression ratio increase significantly with these enabled (will get the specific figures). I'll post a guide on how to enable these features, since feedback is slow and we need more data.
As requested the policy configuration has been made easier to edit existing rules.
Express throughput has been reduced to 6/60 mbps up/down. Remote peer sites reduced to 3.
-
Thanks Antonie,
This is great news. We have been testing but RC 2.0.1 has been so stable that we don't have any bugs to report. I will look forward to the guide so we can do some further testing.
-
v2.0.2 available for download.
UPDATED: Download Wanos (http://wanos.co/wan-optimization/download)
2.0.2 changes notes (http://wanos.co/forum/index.php?topic=152)
Issues noted:
One or two reports that v2 is not running correctly on Hyper-V Server 2012 R2.
After the update, if the datastore partition might need to be reset.
Performance gain is causing more aggressive memory usage.

From my experience using wanos in a production environment for the last three months I can say that you guys have a fantastic product! It has exceeded my expectations in just about every way. I think the pricing structure in place is fair too, especially considering what Riverbed and Silverpeak charge.
That said, with the limits on the free edition being 6/60 it may be a hard sell for IT to convince management to invest in the plus version with no unrestricted performance data to sell them on. Perhaps the free version can be setup to initially run without limits for a short amount of time... a month perhaps? 30 days is more than enough to give people an idea of how wanos plus will perform in their environment.
With a proper marketing strategy, I can see you guys taking a huge chunk of the WAN optimization market from Riverbed and Silverpeak.
-
Hi Jeremy,
Thanks for the awesome feedback. I agree on the initial trial. We have actually already decided to go that route and enable Express/Plus after the trial. We are on it.
We think there are many companies out there that could benefit from WanOp, but just not interested due to the price tags. Maybe there is an untapped market here. If we can get more companies interested, I think Silver-Peak and Riverbed would actually benefit from having a low end product around.
I agree on the marketing... working on it.
-
Thats great!! Thanks!

I honestly dont see wanos being "low end". The performance, reliability, and the level of refinement are far greater than one would expect out of a product from a relatively small company. Getting the right people to take a look is the challenge. Spiceworks would be a nice place to be popular.
BTW, if wanos were available for review on Spiceworks, I would be happy to post a review.
-
Yes, I agree Spiceworks can potentially be great. We'll have some ads running on Spiceworks in April. The other features like commenting and reviews cost an arm and a leg. Maybe one day :)
