Disk Size

To determine the minimum disk size for your servers, consider the following:

• The total number of messages likely to accumulate at the server at any one time and the size of the messages.
• The disk space used by the MSMQ files and potentially, the MSMQ installation folder.
• The size of the MQIS database.

Note When an MSMQ independent client or server runs out of disk space it can no longer send or receive messages, nor can it create queues.

For more information on determining the appropriate size of the MQIS for your enterprise, see "Determining the Size of the Information Store" later in this chapter. For more information on determining disk space requirements for your message queuing, see "Determining Message Queuing Disk Space Requirements" later in this chapter. For more information on the error messages returned when a computer has insufficient disk space to send or receive messages, see the Microsoft Message Queue Server Software Development Kit (MSMQ SDK) documentation.
