I would agree - we started using one at work (the 760 I believe) with 128GB of online RAID 4 storage - YUM!

RE: [PHP] load balancing with php/apache?
A NetApp (Network Appliance) is a big RAID that uses multiple scsi drives to create a single transparent volume which, with CIFS (transparent filesystem) can be used by any OS. They are v fast, use NVRAM buffering and can go up to post terabyte storage capacity without worries. Oh and they start at 60k pounds sterling But they are great.

Re: [PHP] load balancing with php/apache?
Wasn't directed quite at me, but I'll chime in nonetheless We used LocalDirector for awhile, with it's 'sticky bit' functionality, and it basically didn't work with AOL. I just looked at the coyote product and they claim it works with 'large ISP' proxies - maybe a veiled reference to AOL directly (why not just say AOL?). Do you have any more info on HOW they do this? The only thing I can think of is that they code it recognize particular IP blocks known to be proxies for AOL/mindspring/etc and route ALL traffic from these to a particular box, which doesn't seem terribly balanced. OR... they drop a separate 'cookie' or similar header data piece between the server and the client and track that. Either way, it seems a bit expensive, although cheaper than LD, last time I checked. Personally, we do the 'stateless' model with session data in a database - works fine. Your coyote solution is still stateless, but the session data is kept local to the webserver. Problem I see with that is that if you need to take a particular machine offline, hundreds of people could lose their session data. Same can be said of taking the database offline, but taking a db offline will probably affect the whole site anyway. Part of the benefit of an intelligent load balancer is that you can remove/take down machines for maintenance/upgrades without worrying about the impact on the visitors. Am I missing something?

RE: [PHP] load balancing with php/apache?
unfortunately not because it is not opensource. I did want to make it clear that sessions is a gereric word. Thus, when it is said, it shouldn't be mis-understood as to be PHP Sessions, which obviously is not a generic word.

Any of the above. It's up to you. Most people probably store the session info in a database. But you could also do it in a shared drive. But I got a little static a while ago when I suggested storing shared session data on an NFS mounted drive. NFSes are too slow I guess.

Haven't had a chance to set > it up myself yet. Definitely something for the TODO list. LVS with linux-ha is a win-win situation. Even if you loose a LVS, the failover is transparent. The connections hang for about 5-15 seconds, then transfer over to the other machine. With the traffic that we have, we opted to use direct routing, this way there is no translation (thus no additional CPU on the LVS machine) needed for the answers; the web servers talk directly back to the client themselves. We were planning on using Local Directors, then cost became a major issue. I'm actually glad we did it this way, because personally I like envesting my knowledge in open solutions rather than learning proprietary OSs and strategies.

RE: [PHP] load balancing with php/apache?
The session id is not an issue, but yes, obviously you will need to store the session data itself somewhere where all the machines can get at it. So either on a common NFS share, ldap or some sort of database. PHP's session handling allows you to write your own backend session datastore functions using session_set_save_handler() http://php.net/manual/en/function.session-set-save-handler.php -Rasmus On Sat, 13 Jan 2001, Cal Evans wrote: > How does it deal with sessions?

Re: [PHP] load balancing with php/apache?
We've used local director in the past, as well as the 'f5' product (big IP? - I forgot the company name). Maybe it's 'big ip' from f5. Shows you how much we think about it - it just does it's job. As others pointed out, you can go with a software version under Linux, and I think W2k enterprise has some type of load balancer available for it too. All a load balancer will do is route requests to different web servers - what the web servers do with the requests (run ASP, PHP, Perl, CF, etc.) is entirely irrelevant to the load balancing situation. The 'enterprise' issue with respect to PHP is a bit of a red herring, IMO. VBScript doesn't do load balancing, and that never stopped anyone from deploying ASP pages... Good luck. :) Erick Papadakis wrote: > hello people > > this might be a very silly question, but folks in my > company have now started asking some enterprise > questions like "sure, we'll do php but how about load > balancing?" i have a feeling that this can be achieved > with some caching on apache? how can i achieve this? > > thanks/erick > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

We have 2 load balancers with the HA package and 6 PHP webservers running behind it (with a central DB server). In short, it's possible and works quite well.

Haven't had a chance to set it up myself yet. Definitely something for the TODO list. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Surely they don't expect a scripting language to be doing load balancing for them? There are dozens if not hundreds of ways to load balance your web server.

Re: [PHP] load balancing with php/apache?
We use Cisco LocalDirector to do load balancing in our web cluster. It's very configurable and has worked very well (so far!). - Tim > this might be a very silly question, but folks in my > company have now started asking some enterprise > questions like "sure, we'll do php but how about load > balancing?" i have a feeling that this can be achieved > with some caching on apache? how can i achieve this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
