With the imminent release of macOS Big Sur (is it 10.16 or macOS 11?) then it’s time to move from 10.14.6 Mojave to 10.15.6 Catalina. Until now that meant macOS 10.14 (Mojave). I always recommend being a revision behind the latest. Our day to day production Xsan systems do not run beta software, not even the latest version of macOS, they only run tested and safe versions of macOS. With all the excitement of Big Sur in the air, it’s time to look at Catalina. A new macOS beta cycle with Big Sur is upon us. AFP vs.Summer time is beta testing time.macOS Server: migration to HELIOS Server.Guide to a perfectly matched soft proof.Home News Support for Apple Xsan server solutions This can be tested with the HELIOS File System Test.Īll HELIOS 4th generation and upcoming server products have been tested successfully. HELIOS has its own file exchange system so EtherShare does support file exchange! This is needed to save new versions of existing files while preserving the file ID (Alias reference). (Saving existing file failure can lead to data loss)ĪFP and HFS have a file exchange feature. This can be tested with the HELIOS File System Test.įree space is not shown in Finder but Quota limits are enforced. HELIOS has its own Desktop database so the server find file feature is fully supported by HELIOS server solutions. "dt cp", "dt rm" will handle files directly on the server.Īpple AFP / Xsan file systems have no Desktop database which results in long find sequences. Manage files and folders always remotely via AFP / SMB servers by HELIOS. Use HELIOS file services only to ensure consistent file names. HFS and Xsan store umlauts and special characters with a different encoding. Xsan is case-sensitive like UFS file systems, e.g. For server solutions each Xserve must share an exclusive folder per Xserve only, otherwise customers will run into serious problems such as damaged files or seeing a different file content depending upon which Xserve accesses the files. For some custom applications like an Xsan based movie editing application which is directly working as an Xsan node and using special Xsan APIs to flush the data, they may share the same files. There is a way to flush data but we do not have control over the applications (like InDesign, QuarkXPress, Photoshop, web servers, databases, file and print servers, asset management). This means you cannot share the same data/folders with multiple Xserves because each Xserve may see data from its local cache and not the data the second or third Xserve has just written. We learned from Apple that every front end Xserve is doing its own read and write disk caching unless an application calls a special file sync for each write and read call. Tests with UNIX tools and QuarkXPress revealed that a file may show different content when viewed from different servers In general, this setup is not appropriate for typical file server usageįile and record locking concurrent access damages files This configuration is only suitable for applications that are specifically written to be compatible (e.g. Multiple Xserve serve the same HELIOS volume Saving existing file failed (Can lead to data loss!)Įach Xserve serves a different HELIOS volume The HELIOS File Server bundle enhances Xsan systems, and brings fully integrated cross-platform networking to Mac, Windows, and Web users. The HELIOS UNIX desktop utilities (mv, rm, cp, ls.) properly handle file copies, etc., directly on the server by preserving the Macintosh specific resource and Windows file streams information, preventing data loss and assuring full cross-platform compatibility. The HELIOS advanced printing system brings high-end print server features and reliability, while HELIOS adds remote server administration for Windows, Mac OS X and UNIX / Linux users. The HELIOS built-in server fail safety ensures that if one or more processes fail, all other running users are not affected. This is more than 1000 times faster than the Apple AFP Server using the same Xsan volume. HELIOS EtherShare server-based find file will find any file on an Xsan volume within seconds. HELIOS server solutions bring many reliability and performance benefits to Xsan. HELIOS fully supports the Apple Xsan file system with all HELIOS server products.
