Configuration / Re: NFS optimization

« on: August 25, 2014, 10:58:39 AM »

Hi,

Where possible and practical a simple speed test is a good indicator that optimization is in effect.
The free traffic and network graphs can also be used to see the difference in lan0 and wan0 bandwidth.
Datastore %, Disk usuage, Disk io and memory also indicate whether optimization is in effect.

These are high level views. More info under Checking reduction rate and reporting tools

Hi there,

The best location would be to have the cache on the user side of the wanos. Where possible, but not essential.

Having the Core and Edge back to back will not provide any benefits. Two devices are required because they need to be at two locations (either side of the slow or congested link). In this scenario it would be required to have a device at the ISP side.

Does the ISP not offer any hosted services?

Hi,

Yes, it is possible to use a Configure Single Physical NIC for VMware vSphere (ESXi) and use the inside/outside vlans on this trunk. It has some drawbacks in that it does not support failover and only the two vlans can be trunked on that port.

Placing the riverbed and wanos back to back is working without incident in other networks, so it should be fine. Just to be extra safe, bypass the Riverbed optimized networks on Wanos and the Wanos optimized networks on Riverbed.

Troubleshooting / Re: Network disconnect after sometime

Hi Hoyin,

This is known to happen if either side is running a different version. Please ensure both sides are running the same version.

Do you have some more information about your configuration e.g. network topology, vlans, interfaces. Is this a VM or a physical appliance? If VM, is the Wanos lan0 placed in the same VM network as the servers?

Also try adding specific traffic rule policies for the source and destination networks that need to be optimized.

Hi there,

To clarify the topology, does the L2 VPN represent the wan and therefore the two core switches are in separate locations? Users and Servers are on either side of the core switches?

If the servers are on a single vlan then the wanos lan0 can be placed in that same port group. Wanos wan0 would link via a vlan to the core switch.

Although that will work, a cleaner design would be to configure two nics to the core switch. One in the server/lan vlan and the other in a new firewall/wan vlan that the firewall is also in.

Examples of one side of the wan:
ESXi servers vlan 100 --- lan0-wanos-wan0 --- FW vlan 200

If the core switches are doing Layer3 routing for multiple vlans, then the Wanos is placed between the core switch and the firewall:
LAN vlans 0-100 --- L3-switch --- lan0-wanos-wan0 --- FW

I hope it helps, but if not, lets go back to the current topology in case I misunderstood it.

Troubleshooting / Re: wanos throughput on kvm

« on: August 18, 2014, 12:40:27 PM »

Hi Peter,

My knowledge of kvm is very introductory, but Silver-Peak supports kvm, so there is a way to make it work well. They also recommend the virtio nic and disk, but since you have that configured, the bottleneck must be somewhere else.

Does edge and core produce the same throughput results?

Would it be possible to run the following test:
first disable the wanos processes (/etc/init.d/wanosd stop-all) from the console, then run:
Test 1) click -e "FromDevice(lan0, PROMISC true, SNIFFER false, METHOD PCAP) -> Queue -> ToDevice(wan0, METHOD PCAP); FromDevice(wan0, PROMISC true, SNIFFER false, METHOD PCAP) -> Queue -> ToDevice(lan0, METHOD PCAP);"
Test 2) click -e "FromDevice(lan0, PROMISC true, SNIFFER false, METHOD LINUX) -> Queue -> ToDevice(wan0, METHOD LINUX); FromDevice(wan0, PROMISC true, SNIFFER false, METHOD LINUX) -> Queue -> ToDevice(lan0, METHOD LINUX);"

Compare the throughput of test 1 & 2 with the wanos Core and Edge results.

Deployment / Re: > Gigabit speeds Hardware

« on: August 14, 2014, 05:46:01 PM »

Hi Bob,

The Ecessa flagship capabilities seems to be in the link bonding and link fail-over technology. This is not something that Wanos is configured to do.

That said, to bond multiple links is relatively simple. Without investigating the PowerLink tech in too much detail I believe the secret sauce will be in the link selection / load balancing algorithms.

Installation / Re: Vmware ESX single physical NIC

« on: August 04, 2014, 01:55:42 PM »

Two notes to remember with a single nic setup:

1) Promiscuous needs to be enabled on the portgroup/vlan level (i.e. not vSwitch):


2) Depending on the switch config, bpdufilter might be required:
interface FastEthernet0/5

 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 30,101
 switchport mode trunk
 spanning-tree portfast trunk
 spanning-tree bpdufilter enable

Yes, I agree, previously this was available but inaccurate since bypassed traffic was included as well. Coming soon.

« on: July 28, 2014, 06:37:55 PM »

Hi Luis,

Just for the record, thanks for opening up the access to allow for the bug to be found. It has been introduced in 1.2.2 and a patch will be available shortly. It most likely only affects optimized UDP Fragments (UDP bypassed by default). Will keep everyone informed.

Troubleshooting / Re: LAN IN but no WAN OUT

Hi Luis,

Those symptoms are almost exactly the same as what Fernando saw during the initial install. The last I heard was that he was looking at the Nexus1000v configs.

If the system runs stable and the network configs remain the same, then there should be no reason to see traffic drop from either lan/wan side. Since this is not normal behavior, I am guessing somehow a change on the network layer occurred.

Troubleshooting / Re: Free Traffic Calculation

« on: July 23, 2014, 03:14:35 PM »

Hi LuisP, yes, there are one or two limitations in the free traffic stats and the network traffic graphs are the most accurate. The calculation has been changed in 1.2.2 to take the bidirectional stats into consideration (and hopefully did not introduce this issue, since replication is predominantly one way). That said, the calculation method is due to fundamentally change which will be a big improvement and provide a lot more traffic/session/optimization visibility stats. I'll also take a look at the UDP stats, please bear in mind that this is a beta feature, but glad that its working well.
