The first thing on the list is to be sure and go Exchange 2000 Enterprise as there is no limitation on Storage File.. otherwise, if you go 2K Standard, the Information Store halts at 16GB.. We are only 200+ employees with 8 locations and have 4 Exchange Servers... You didn't say whether you were on a WAN or not... If not, then each site, I would imagine is going to be treated as a stand alone site... Also, if you have mail files larger than 100K, it will be a long haul... we exported everyone to PST's and then imported them once the new Exchange server was up... I haven't had the best experieince with MS migration utility... Good luck -----Original Message----- From: Reuben Siuda [mailto:reuben.siuda@xxxxxxx] Sent: Friday, November 15, 2002 1:27 AM To: [ExchangeList] Subject: [exchangelist] Exchange 2000 Capacities http://www.MSExchange.org/ Hi, the org I work for is currently investigating migration to Exchange 2000. We have 2600 users spread across 20 UK, European and Asian sites. Each office has an Exchange 5.5 server, in its own site. One of our servers has 650 users and a 60GB Information Store. As you can imagine, backup and recovery of this I.S. is something of a challenge. To that end we have a couple of options - split the site into 2 servers of say 30gb - or migrate to Exchange 2000, and use multiple stores on a SAN/Clustered environment. As usual, most of our information stores are loaded with attachments. Try as we do, getting users to change this is not realistically going to happen. Having no experience yet of Exc 2000 I'd like to know if anyone has any experience/recommendations for: 1. Maximum workable number of users on 1 Exchange 2000 server 2. Maximum store size on Ex 2000 3. How well Ex 2000 works on a clustered environment 4. Possible centralisation of all our sites into 1 new site containing all uk users, who would then connect over out lan/wan (256 CIR minimum between all sites, 100mb max). i.e. how well does Exc 2000 work remoteley? Anyway, just a few ideas we are throwing about. Any comment would be appreciated and welcome. Thanks in advance. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: lwilson@xxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
