![]() ![]() TCP vs UDP - TCP: reliable, ordered, heavyweight, streaming UDP - unreliable, not ordered, lightweight, datagrams. Apple asks users to note that this version of the Xsan uninstaller applies only to Xsan version 1.4.2 through 2.2.2 on Mac OS X or Mac OS X Server versions 10.4 through 10.6. Xsan allows shared use of files and volumes of up to 16TB each, in a high-speed optical network. The system ena-bles quick access to large data volumes. the Domain Name System (DNS), the Routing Information Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the Simple Network Management Protocol (SNMP). Xsan is Apple’s 64-bit cluster FS for Mac OS X or Mac OS X Server. By David Nagel 02/20/08 Apple this week released an update to Xsan, the companys 64-bit storage-area network solution designed to allow workstations and Xserve systems to share RAID storage over Fibre Channel networks. UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).Īpplication examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games. UDP on port 311 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level. UDP on port 311 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice. UDP port 311 would not have guaranteed communication as TCP. Guaranteed communication over TCP port 311 is the main difference between TCP and UDP. Xsan puts SAN file systems within the reach of midsize businesses and high-demand workgroups or server clusters. Also tried to follow these steps If your Xsan volume doesnt automatically mount at startup - Apple Support. About Xsan storage volumes on Mac Xsan volumes are based on Redundant Array of Independent Disks (RAID) storage devices. ![]() Attempted to use -mntretryn Mount Xsan volumes with advanced options - Apple Support and that didnt work. Only when a connection is set up user's data can be sent bi-directionally over the connection.Īttention! TCP guarantees delivery of data packets on port 311 in the same order in which they were sent. XSAN Volume fails to auto-mount after upgrading to Monterey 12.3. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Sounds like you have something running on the box that is asking for request on those ports. So unless you have Xsan installed on an Apple OS you will not be getting any Xsan request. The Xsan profile configuration enables you to specify an Xsan server network when: Creating a Profile Editing a Profile Xsan Name Enter the name. TCP is one of the main protocols in TCP/IP networks. Apple Xsan will ONLY work with Apple OSX and OSX Sever. Xsan is Apples storage area network for macOS devices. TCP port 311 uses the Transmission Control Protocol. ![]()
