Table Notes
    1. Depends on application and connected users.
    2. 3000 instances of 346 unique open files.
    3. 2000 recommended.
    4. Mac OS versions prior to System 7.5 support a maximum volume size of 2 GB. System 7.5 and later support volume sizes in excess of 4 GB. However, because AppleTalk Filing Protocol (AFP) version 2.0 is limited to volume sizes of 4 GB or less, the maximum AppleShare volume size remains 4 GB. (see note below)
    5. AFP 2.2 adds support for 2 terabyte volumes. Using AppleShare Client 3.7.2 or newer with AppleShare IP 5.0.2 or newer allows the use of these larger volume sizes.
    6. Maximum number of connected users is subject to licensing restrictions. The maximum limit of 500 users is only available in ASIP 6.x and may require additional memory. For details, see article 24624:" AppleShare IP 6: Read Me"
    7. Clients will see all the items on the server but the free space reported will never exceed 1.9 GB.
    8. ASIP 5.x and 6.x utilize AFP 2.2, which allows for over 4 billion (2^32) shared files on a volume. In practice, the maximum number of shared files will be the same as the maximum number of files that can be stored on the volume. For HFS volumes, this is 65,536 files. For HFS+ volumes this limit will be significantly higher.
    9. The limit of 346 unique open files is a limitation of Mac OS versions prior to Mac OS 9. Mac OS 9 and later support up to 8169 unique open files. AppleShare IP 6.3 and later, when used with Mac OS 9 and later, can support up to 3000 open files, all of which may be unique (depending on file usage by other parts of the system).

See Article 24601: "Mac OS Extended Format: Volume and File Limits"

NOTE: With AppleShare Workstation (client) software older than version 3.5, the maximum volume size is a few hundred kilobytes less that 2 GB. This was fixed with version 3.5.
