Is 16 Million VLANs enough for you? - Ahmed

Ahmed — Thu, 07 Mar 2013 06:34:35 -0400

Hi Edgard,
The terminology Mac-in-Mac is a misnomer used to represent the L2-in-L2 ecapsulation (+TRILL Header) [1].
we used this terminology to classify approaches according to transport layer (exp: VXLAN uses MAC-in-IP).
I agree with you that using such terminology can create confusion.
Indeed, the mac-in-mac (802.1ah) is better suited for SPB or vCDNI.
Concerning the VNT extension header, we have based our work on [2] and [3] to add a TRILL header extension containing the VNI (virtual network identifier) to create several logical networks.

I hope this will help you understand the difference between our approach and the SPBM one.

Are you using TRILL and SPBM interchangeably in your terminology? TRILL "standard" doesn't provide mac-in-mac support yet what you are describing is a pure SPBM implementation. Can you clarify what are you actually doing?
thanks

Hi Vincent,

What I said in my first comment was just an example based on a rapid three minutes test without any particular configuration or optimization.
When I said that the amount of memory transaction already used is unknown in advance, I was speaking about a machine in production where we cannot verify how each VM is used.

The current implementation is aimed to be deployed on the physical node.
Due to the fact that VM are not supposed to be virtual routers or similar, we don't use, at the moment, any pps optimization mechanism.
This is also why we don't have, at the moment, a pps measurement in optimal conditions which, in my opinion, is meaningless in such a use case.

The next step could be to implement a VNT compliant gateway to connect data centers with each other. In such a situation, the pps has indeed a real impact on production site.
So while doing this implementation extreme attention should be given to pps that can be handled.

Ahmed,

You consider only a best effort packet processing along with virtualization because of uncontrolled memory latencies : VM->BRIDGE and BRIDGE->NIC. That's why 300Kpps maybe.
Please, have a look at :
http://www.multicorepacketprocessin...
As you can see, even using software, you can control such latencies and process packets within a well defined number of CPU cycles, optimizing the use of CPU caches, avoid the overload of the memory controller thanks to DDIO and sustain few Mpps.

From our developments and measurements we get with ESX kernel, the librte_pmd_vmxnet3/DPDK and the 6WINDGate's fast path we had confirmed that you can get Mpps. With Linux and its KVM/Qemu, the performance can even be higher with a fast path between the guests and from the guests to the networks.

For instance, for your case of a VM with 3 cpu, this VM has a potential to generate ~15Mpps, so its VM2VM can become part of "routing".

In case of TRILL, I feel this implementation should sustain such Mpps too, up to the HOST_BRIDGE (vSwitch).

@Vincent:
It's a tricky question Vincent,
For example in a VM(3 cpu and 2G of RAM) to VM (3 cpu and 2G of RAM) communication we have more then 300 000 pps (64B packets) with netperf.

But it's not as simple as that, in a virtualized server we almost never speak in terms of pps due to all difficulties that we have to predict it.

In fact our bottle neck is memory access latencies [1][2], as VM->BRIDGE consumes some amount of memory transactions, BRIDGE->NIC consumes another amount of memory transactions,
we must also take into consideration running process on the servers which consumes unknown of amount memory transactions, memory transactions to generate a packet,
context switching due to virtualization... Finally to add another complexity layer, each server may have a different memory frequency. So as you see it's really a hard problem.

We generally speak about pps in routing context in router where all memory transactions are known in advance (no virtualization nor context switching...)
In a router to forward a packet from port A to port B we consume X memory transactions so we divide memory frequency on X and we have an idea of the pps

But you can be sure that each VM will have a decent amout of pps.

Simple Hosting Turns One Year Old - Thomas (Gandi)

Thomas (Gandi) — Sat, 26 Jan 2013 11:39:59 -0400

For our part, we are a dead serious company, and we think that the level of BS in the industry is what is ridiculous and offensive.
Of course, we realize that our slogan will shock some people. What we are trying to do is let everyone know that they do not have to put up with being BS'ed by deceptive marketing campaigns, empty promises, and evasion by the companies they buy domain names and hosting services from . There is an alternative at gandi.net.
We accept that we can't use our slogan on the radio, but that's ok: we don't advertise!

But either way, it's been a nice service for this first year!

Gandi Simple Hosting Now Live in the USA - Pete S.

Pete S. — Fri, 20 Jul 2012 12:33:29 -0400

Just a quick followup: hosting in the Baltimore facility is extremely fast from various North American networks (the connections to Europe are also excellent as well, but one would be better off hosting in Paris for obvious reasons).

I've tested an S-size Simple Hosting instance and a separate VPS, both in Baltimore, and things work very well indeed. Well done.

One very handy perk of Simple Hosting that I hadn't noticed before: the Apache daemon in one's instance runs as the same user as the user themselves. This makes setting up occasionally-annoying-to-setup-on-shared-hosting services like WordPress quite simple, as there's no fussing around with permissions (WordPress auto-updates, for example, require that Apache have write-access to the WP installation, necessitating that the user assign correct permissions to the various files and directories. This isn't an issue with Simple Hosting.)

Anyone who wants three months of Simple Hosting for the price of one, use the promo code "SIMPLE" to sign up for 66% off on a quarterly-billed instance!

Note: this is good for your first instance of size S. It won't work if you try to use it to renew an existing instance.

"Try out our simple hosting, compare it to the competitors for speed, power, and price."

Reading that makes me feel so proud to do business with Gandi. It is extremely uncommon to see a business make such a proposal in America. It probably is in France as well. Marketing today is very focused on ignoring the competition, or attempting to prove that you are the best. Well, you know what? Gandi is not the cheapest registrar, and maybe not the simplest for everyone, but it is certainly a respectable and honest company with a quality product, and that means so much more than price or empty assertions of being "#1"... Thank you guys.

Excellent! Although my various sites are small, most of the visitors are in North America and so hosting in North America will reduce latency and improve performance for them.

It sounds like your Baltimore operations are expanding rapidly. Keep up the good work.

One (hopefully) minor feature request: would it be possible to offer PostgreSQL in addition to MySQL?

Thank you! The memory and network interface upgrades applied without a hitch and the ~2 minutes of down-time to increase the storage to 12 GB went smoothly.

However on the kernel and boot line options page, I do not see the Linux 3.2 kernel in the drop-down list, but I do see that the 2.6.36 is indeed marked "(deprecated)". How do I switch over to the 3.2 kernel?

Jason,
With clear instructions even mere mortals can achieve the unusual. In the case of Gandi Simple Hosting, all that is needed is a TXT record in the zone file at your registrar. See http://wiki.gandi.net/en/simple/shs...

With Gandi Cloud Hosting, it's just a host on the Internet: no dependence on having your domain at Gandi in either case.

I just read this news posting for the first time, and noticed the phrase "there will be a bandwidth quota added". That concerns me greatly; I found gandi's use of unmetered bandwidth incredibly awesome, because it meant I could easily predict my costs every month. While I can understand wanting to have the option of having a huge amount of burstable bandwidth and paying bandwidth charges, I hope you continue to keep the option of having a modest amount of flat, unmetered bandwidth.
