Loadbalancing with Opensolaris - or: PSARC 2008/575

Thursday, November 5. 2009

An nice addition to the networking functionality has found its way into the Opensolaris codebase: PSARC 2008/575 ILB: Integrated L3/L4 Load balancer. This code enables Opensolaris to act as a simple load balancing device. It already contains features like acting as a loadbalancer in NAT or direct-server-return-mode as well as ping/udp/tcp and scripted health checks. You will find more information about this new feature in the case log of PSARC 2008/575.

The configuration is pretty straight-forward. To configure a loadbalancing on a group of four servers you have to use this commands:

ilbadm create-servergroup -s servers=webserv1,webserv2,webserv3 webgroup
ilbadm add-server -s servers=webserv4 webgroup
ilbadm create-rule -i port=80,vip=15.192.0.0,ipversion=IPv4 \ 
	-m lbalg=hash-IP-port,type=NAT \
	-o servergroup=webgroup webrule

I think as soon as this code is available in Opensolaris, i will try to marry it with the KSSL functionality. Would be nice, to use both functions to create an SSL-offloading loadbalancer

Scarry, I was just looking for a DSR load balancing/failover service at work today. I did however find that our current firewall already had that built in, otherwise this maybe would have been an option

take a look at zeus, seems like a really competent SW loadbalancer, downloaded the virtualbox image just to give it a try and it seemed to have a competent set of features!

I know their products reasonably well, they deliver good products ...

But not everyone wants a full featured load balancing software. It for the people who just wants a simple device without further software. For the same people using similar features in Linux for example at the moment.

one big difference between zeus' offering and ILB is that ILB performs the actual packet forwarding in-kernel, and therefore avoids the dual crossing of the kernel-userland boundary that other, userland-only products have to perform *for every packet*.

btw: ILB's admin interface is abstracted into a library, so Zeus or whoever is interested could easily refactor their solution to benefit from ILB funcitonality.

Gibts bei Osol die Möglichkeit von L2-basiertem Balancing?

#3 Günther on 2009-11-06 13:01 (Reply)

L2 Persistenz oder L2 Balancing durch austausch der MACs mit identischen IP auf den Interfaces ?

Der DSR-Modus entspricht einem L2-LoadBalancer...

question to all: to use ilb it's enough to update my 2009.06 to the 127 build? because i had a lot of troubles tryin to download the ilb source from src.opensolaris.org...

ILB bits will appear in build 128, so updating to 127 won't help you, I'm afraid.

#4.1 Michael Schuster on 2009-11-25 09:05 (Reply)

Yesterday I updated to Dev Build 130. I don't find ilbadm command. I can see there is a man page for ilbadm but command is not there. Perhaps it would have missed ? I did find command on my all filesystems. couldn't find anywhere.

You have to install it: pkg install SUNWilb

Hi,

we're just finishing a DNS LoadBalancer Appliance based on ILB. The preliminary results
are very good. Instead of VRRP we wrote our own HA handling.

CU, Martin Seeger
