VDEO Box 6000 users of the mail server hardware configuration be? Made here do not know whether or not appropriate and, if appropriate Bamboo please delete. A friend of mine wants to be a mail server of around 6,000 users, the size of each mailbox VDEO. (May later be increased to 12,000 users) According to previous articles here, is calculated as follows : 6000*1%=60 months with enlarged to 100 users : Each user process : 20M*100 = 2G, and some people say that will not be so much, it bars 1G * 20% of storage space : 6000*500M =600GB Bandwidth : Use care room shared bandwidth of 100M * 2 : P4 CPU? Taking into account the initial investment is not very large, maximizing the use of free software (the study had their more) What should use the hardware performance of the server? Multi-CPU or CPU? The HP ProLiant DL140 can? If the use of an MK Xeon3.06 GHz 1GB of PC2100 DDR SDRAM, the operating speed of 266MHz (MK) Price 13,000 yuan Add audio cards and hard disks, backup tapes with the plane, do not know what will be the ultimate price? VDEO Box 6000 users of the mail server hardware configuration be? Software, the operating system used recommend? RHEL seems to be to spend money to buy, FreeBSD is not undertaken, nor do I know whether there are relevant server hardware driving? Hardware, Also seems to have a firewall, can not afford to buy the hardware, the software only. It also needs a machine. Whether it be a high-grade PC? VDEO Box 6000 users of the mail server hardware configuration be? This is the nature of the 6000 users users, the very important VDEO Box 6000 users of the mail server hardware configuration be? --> RHEL do not have money, a lot of online download. As for firewalls, operating system level in more than find a solution. The economy does not seem to buy. Iptable+ some safety inspection software. SElinux can be used (rhel this model. Like. . ) Freebsd should say it is relatively good choice, but if not, then the minimum is unbearable torment. VDEO Box 6000 users of the mail server hardware configuration be? --> Mail server, in case the money is very tight, prefer to go to bars more memory. In addition, it is estimated that it is doing business offices upstairs bar. Peak usage in the business offices, with very high. Smtp/pop3 but the same time. Assuming a 10% to 600 count is made (of course not as high as the actual, not the normal, major isp will be made only 2,3k months), has already included the SMTP and pop. The Web also made several pre-1,10. If xeon said. Have enough memory, the 1000 should be able to link to bear. But if there are many items during the assays. Risk assessment : cry : VDEO Box 6000 users of the mail server hardware configuration be? Cannabis : the government is similar to users, which is used to transmit documents and daily reports, the type of notification, it is estimated that the daily volume of the letter were not significant, the annex will not exceed 5~10M VDEO Box 6000 users of the mail server hardware configuration be? Envoy : RHEL back situation seems not buy, the escalation of fighting Patch is not online? Should also be, at least where the number of user groups, the problem is easy to seek help. Enterprise offices is done, as you said, with the high volume of concentrate. So I think in the end there is a double CPU2G server then? Two single server or CPU1G good memory. Personally, I tend to 1G memory of the two CPU servers, two IP addresses, through the MX records do load balancing. However, if two servers, it will inevitably involve the type of disk storage cabinets equipment. . . Ah can not afford to buy too expensive now VDEO Box 6000 users of the mail server hardware configuration be? Thank you for your reply to, please continue. VDEO Box 6000 users of the mail server hardware configuration be? 1G two CPU servers, certainly better. But do not load balancing. Can smtp.pop3, web separately. But many more machines to handle trouble. You should have a separate gateway, firewall bars, not superstition operating system configuration. If we really need 600G storage arrays requires the VDEO Box 6000 users of the mail server hardware configuration be? If users are those who are idle, it need not worry about the actual load. Certainly with a relatively low. VDEO Box 6000 users of the mail server hardware configuration be? To save money, or 146GB hard disk RAID5 * 6 to be, okay? VDEO Box 6000 users of the mail server hardware configuration be? RAID5 can do, but my experience is very often hard disk went bad MAIL system, the reasons for the large number IO disk kept in the Seeking the manipulator. So there must be one to two blocks HOTSPARE, if it is six hard disks, dual-channel application of RAID card must be to improve performance. 12,000 customers by the operator, which requires Taiwan WEB server memory as possible, two SMTP/POP server, a database server, mail server database can be linked to the hard disk. I personally think that there is a choice of OS choice FREEBSD, Covert is a compromise choice under Windows is the choice Another point is best not to walk NAS framework, unless you buy a special NAS. VDEO Box 6000 users of the mail server hardware configuration be? --> I have decided to do a POP3/SMTP HP DL380 server, a Web server, so DL145 machines VDEO Box 6000 users of the mail server hardware configuration be? VDEO Box 6000 users of the mail server hardware configuration be? NAS can not afford to buy, they can not afford to buy a good point in the tape machine. Web server's hard disk had to be expanded to do the back-mail. . . VDEO Box 6000 users of the mail server hardware configuration be? 6,000 users on a number of machines. VDEO Box 6000 users of the mail server hardware configuration be? VDEO Box 6000 users of the mail server hardware configuration be? If FreeBSD yes, more stable version? VDEO Box 6000 users of the mail server hardware configuration be? If the use of freeBSD, recommended 5.3 VDEO Box 6000 users of the mail server hardware configuration be?
