4.1.0 HP Polyserve Matrix Server Release Notes (T5392-96068, October 2010)

Version: HP PolyServe Matrix Server 4.1.0
Description
This document describes the HP PolyServe Matrix Server 4.1.0 release.
Supersedes HP PolyServe Matrix Server 4.0.0
Enhancements
HP PolyServe Matrix Server 4.1.0 provides support for Microsoft Windows Server 2008 R2 Standard
or Enterprise Edition (64-bit).
Installation instructions
See the HP PolyServe Software installation guide for installation instructions. For upgrades from an
earlier release, see the HP PolyServe Software upgrade guide.
Supported filesystem features
The PSFS filesystem supports a wide variety of NTFS filesystem interfaces and semantics. It smoothly
integrates into existing Windows environments, supporting all of the standard filesystem read, write,
open, and close calls and simplifying application deployment and scalability.
The PSFS filesystem supports the following features of the NTFS filesystem:
• Alternate Data Streams (ADS).
• Byte-range locking. PSFS supports both local-node and cross-node byte-range locking.
• Cached and non-cached file access.
• Case-insensitive naming.
• Case-sensitive naming.
• Content indexing. PSFS support is the same as the FAT filesystem. (See “Unsupported Features”
for more information.)
• Directory Change Notification (DCN). PSFS supports both local-node and cross-node Change
Notification.
• Disk quotas.
• 8.3 short file names and name tunneling.
• Hidden, readonly, archive bits (and so on).
• Memory-mapped files. PSFS support is for the local node only; memory mapped file data is not
coherent cluster-wide. Memory-mapped sparse files are not supported. (See “Filesystem Semantics”
for more information.)
• Open by File ID.
• Opportunistic locking. PSFS supports coherency of client-cached data over a single CIFS server
and over multiple CIFS servers sharing the same filesystem.
