Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4401 Loc: New Jersey	Anybody using SUS? Any comments - pro or con? We have a KiX-based tool that automates the install of service packs, hotfixes, and applications and their updates, but management is considering moving to SUS. Just want to get some other opinions. Thanks! Glenn _________________________ Actually I am a Rocket Scientist! $\:D$

New Mexico Mark New Mexico Mark Hey THIS is FUN Registered: 2002-01-03 Posts: 223 Loc: Columbia, SC	We've played with SUS some. It works well and it is free. That is enough to commend it in my eyes. Oddly enough, our management is resistant to SUS. Go figure. Just FYI, a very modest server can support quite a few clients. This is a great use for a server that is no longer cutting-edge, but not quite ready for retirement. Mark

Does not support IE updates...OS updates only Cannot force updates on users that are local admins...They have to accept update Edited by CitrixMan (2003-12-08 08:16 PM)

Richard H. Richard H. Administrator Registered: 2000-01-24 Posts: 4946 Loc: Leatherhead, Surrey, UK	The biggest problem we have with SUS is bandwidth management - there isn't any. As some of our sites are 24K CIR (they are thin client sites) this causes major problems. We are addressing the problem with a hardware badnwidth management device, but support for "trickle transfer" would have helped a lot. The bandwidth management provided by the web services is not any use, as it chokes the site you are downloading from, not the one you are downloading too. It also implements the limits by denying or aborting transfers, rather than rate controlling them.

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4401 Loc: New Jersey	Richard: That illustrates one of my concerns with SUS - you need to copy the patch to each workstation or server at each site. My Kix based software deploy tool works with WAN structures by using a share at each site (even a share on a workstation) and maintaining synchronization of files with a master site. Then, all other systems at that site utilize that share for local updates. Synchronization occurs after hours, when bandwidth is generally more available. Systems install OTN from the local share, and automatically determine the closest available share via a subnet database. I'm also uncomfortable with "yet another service" running on servers. If I review how much CPU time is allocated to "non-application" services that monitor, health-check, and update our servers, it often reaches 35-50%!! That's scary.. Anyway, 24K CIR seems thin, even for thin clients if you have 4 or more.. what is the burst rate on your circuit? If you have a 56K or better burst, a local server or share might help with overnight replication. Glenn _________________________ Actually I am a Rocket Scientist! $\:D$

Les Les KiX Master Registered: 2001-06-11 Posts: 12734 Loc: fortfrances.on.ca	We use SMS2 with the SUS feature add-on. Looking forward to kicking the tires on SMS 2k3 as it purports to have drizzle. I think SUS is fine for a small shop with decent bandwidth. Sure you could do it in KiX too if you have the skill and the time. _________________________ Give a man a fish and he will be back for more. Slap him with a fish and he will go away forever.

Richard H. Richard H. Administrator Registered: 2000-01-24 Posts: 4946 Loc: Leatherhead, Surrey, UK	Burst is line speed - 64kbps for these circuits. The problem is not a general speed issue - I could care less if it took 24 hours to transmit an update. The main issue is that these are thin clients, which mean that they are extremely susceptible to changes in latency. Even small transfers will monopolise the link and make applications unusable. Each of our machines is configured to request the updates from an server whose DNS name is individual to the machines location. Initially the DNS record is a CNAME for the main repository at head office, but as SUS enabled servers are rolled out the DNS name is changed to point to the local server to relieve bandwidth. There is a gotcha with this method, which is laptops, tch.
