    PDMWE for multi-site collaboration?

    Marcus Monaghan
      A few questions about PDMWE-
      1) Will PDMWE actually replicate a vault between two sites across a slow connection (1.5mbit/s) reliably, and with decent performance?
      2) Will it control access to the vault fast enough to avoid conflicts while collaborating on designs across this connection?
      3) Is a WAN optimization appliance (e.g. Riverbed) necessary?
      4) Is PDMWE fully compatible with a WAN optimizer on this connection?
      5) Is PDMWE planning on handling configuration revisions similar to DBWorks functionality, and if so, when?

      Thanks!

          Thanks!

          I could really use some advice here. If anyone has some experience with this they are willing to share, it would be much appreciated.

            1) "Decent" is a pretty relative term....it depends on how often andhow much of the data changes, and of course how quickly the othersites will need newly modified files. Knowing your connectionspeed, the amount of data you think you will need to copy, it comesdown to simple math on how well your connection will keep up withyour needs.2) Since the database is not replicated, control accessshould not be a problem over a slow connection3) No optimization isrequired4 & 5) Sorry, I don't know these

              Marc or anyone,

              Have you tried this and been successful/unsuccessful?

                Hi Marc,

                We had PDM replication running over an adsl VPN (512kb average speed) 12 SW users at each site, imediate file replication was not very good, but we scheduled it overnight and it worked well. That same connection also ran our ERP system and several other systems all running back to SQL server, in total 60 users at each site, at peak times PDM was slowed down on the users desktop but it never stopped us working with it and we never had a check in/out conflict. we have recently upgraded the connection though as the ERP users were getting a little tired of waiting 1/2 a second for the next screen refresh! . I beleive PDM will definately control access to the vault fast enough over this type of connection. I am unfamiliar with wan optimizers and DB works so couldnt possibly comment on that. Hope that helps!

                  Marc,

                  We have multiple replicated vaults across the country and in China, using all types of connections speeds (T1, Cable, DLS, high-speed cellular). We have not needed any WAN optimizers.
                  It has worked very well in most circumstances. If the connection is dropped then the replicated vault can not be used. We have the affected users switch to the web client in those rare instances. We setup replication schedules during off hours to help minimize "on demand" replication. We have had more problems with dropped connections than with slow connections.

                      Hi Todd -

                      Thanks for your post. Are the dropped connections most prevelent with the China connection or across the board?

                      Also, just an FYI... internally we use Riverbed Steelhead appliances. While not necessary we definately like the speed increases we see (so, does the IT department). We did a try before we buy program and now we have them in Concord, India, Cambridge, UK, Wisconsin and LA.

                      Cheers,
                      Joy

                          We will often have replicated vaults at construction sites. Most dropped connections are due to poor quality DSL/T1 connections at these domestic sites.
                          At these job sites we replicate only folders directly related to the project which eliminates replicating our entire 400 Gb vault. We do replicate our entire vault to an office in Michigan.

                          Hope this helps-

                            I must admit that Boston definitely has the market cornered in terms of sports teams, but OOh how fast your icon changed after yesterdays debacle.

                            Tim...

                                Hi Tim -

                                Darn right .... the offensive line was pitiful.
                                But, props to the Giants... they whupped the tar out of my team and deserved the super bowl.

                                I was not one of the folks who bought into the absurd two touchdown favorite thing. I believed that the Pats were lucky to come away with a win in their last meeting thanks to the late Eli pick....

                                But hey... we Bostonians are used to having our hearts ripped our year after year. Although, that is usually done by the Red Sox... :-)
