Hi, I have two Intel Xeon 5160 rack boxes (2 x Dual-Core, 4GB Ram, 5 HD, 2 LAN ports) to run Win2K3 Server on which I plan to install IDS 11.50 xC2.xx for about 60 users. Considerations I have to address : High Availability, IDS license type/cost, "near-zero" IDS administration, total cost. Please, can anyone advise me about the best solution (pros and cons) to implement beetween the following ? 1/ HDR 2/ When adding an external RAID device a) SSD b) IDS Cluster installation on Microsoft Cluster Service 3/ Any other configuration. Thanks for your comments. Best Regards Henri MOUKOURI

Historically, I've always recommended HDR over clustering because every clustering customer I've known has been bitten by clustering not working as expected. > 3/ Any other configuration. > I would think that HDR would still be the way to go, with the Cluster Manager. -- Cheers, Obnoxio the Clown http://obotheclown.blogspot.com

But I still have some questions on HDR licensing since it's the first time I'll have to implement it. So, please, correct me if I'm wrong : 2 boxes, means 2 WG +HDR IDS licenses. And Cluster install on windows one license. Am I right ? Also, does the cost of HDR option depend on the caracteristics of the secondary (ie. updateable, warm or cold standby) ? And finally, does the Cluster Manger imply additional costs ? Best regards. Henri MOUKOURI

SSD could be Solid-State Disk -- or it could be a typo for SDS as you said. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2008.0513 -- http://dbi.perl.org/ "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."
