This articles describes how to determine the hardware requirements you will have when you migrate your computer from UNIX to Windows 2000.
If you are currently using RAID or similar technology to increase performance, make sure you provide the same functionality on the Windows server.
To determine the current disk space usage for your website under Unix/Apache use du to calculate the total disk space usage for the static and scripting elements of your site. For example:
To calculate the requirements for any database you need to calculate the size of the raw data and then add 25% of this for additional indexing and storage requirements. To get the raw data size for a database, use the corresponding RDBMS dump tool to dump the database specification and data to a text file. For example, MySQL uses the mysqldump utility. Use the -A argument to dump all the databases or specify each database name individually, i.e.
du -sk /export/http/webs
Now obtain the size of the file or files using du:
mysqldump -A >fulldump.db mysqldump database1 database2 database3 >partialdump.db
Then add 25% of the figure to calculate the total size requirements. Allow an extra 50% on top of this for growth.
There will always be one 'loopback' interface.
$ ifconfig -a elx0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 1 inet 10.1.1.2 netmask ff000000 broadcast 10.255.255.255 ether 0:60:8:1d:e2:2b spwr0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.1.135 netmask ffffff00 broadcast 192.168.1.255 ether 0:e0:29:1a:96:73 spwr0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.1.1 netmask ffffff00 broadcast 192.168.1.255 spwr0:2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2 inet 192.168.1.2 netmask ffffff00 broadcast 192.168.1.255 lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 3 inet 127.0.0.1 netmask ff000000
For each network card there will be a corresponding entry in the output. Drivers are listed, and each interface using a particular driver is then numbered. In the above example, we have two interfaces, spwr0 and elx0.
Virtual IP addresses on a single interface are indicated by a trailing colon and virtual IP number. Two are listed in the above, spwr0:1 and spwr0:2.
