Reliable Kerberos authentication with primary domain and child domains Latest POSIX for optimum interoperability Page 1 of 5

2 MANAGEMENT FACILITIES SNAZ Manager Extensively updated and improved remote management web interface HTML only web interface SNAZ Manager now uses HTML only. All Java Applets have been removed for faster response and improved compatibility. NAS Server Configuration Wizard New Wizard assists setting up the NAS system for the first time, accompanied by new Quick Start Guide and more detailed new User Guide. Informative SNAZ System Status Opening Summary screen in SNAZ Manager shows screen operational state of RAIDs, Volumes and Services at a glance. Simplified Navigation Number of menu items reduced from 32 items to 20. Streamlined Network Share Configuration of all protocols used by a share is handled Configuration and Management in a single screen instead of requiring a separate screen Further improved Active Directory integration and compatibility. Improved visibility of stored files and related permissions and ability to modify. On-line help and intuitive support Multi-level SNAZ Manager Administrator Access Control Open File Monitor for each protocol. Easy integration with Windows environments using Active Directory to control User / Groups and Access Right File System Browse function details the contents of all shares in terms of file names and attributes from within SNAZ Manager and enables confident modification of ACLs and DOS attributes Comprehensive Online Help for all SNAZ Manager screens plus specific context related Tool Tips. Improved setup to enable full control Administrator and View Only Administrator access. Allows Admin to see which files are located in which shares and currently being used by Users. NAS SYSTEM PROTECTION SNAZ System Configuration Backup and Restore Improved disk drive diagnostics Improved disk drive and RAID resilience Improved disk drive identification and location Improved diagnostic Event Logging and Alerts Improved security Integrated facility to bundle SNAZ System Configuration and Share Configurations and save them to an offsystem location. Straight forward restore of bundled configuration simplifies restoration of SNAZ system SMART (Self Monitoring, Analysis & Reporting Technology) disk drive diagnostics implemented to enable pre-fail, early identification of disk drives at risk in a RAID so that pre-emptive and scheduled action may be taken avoiding the possible risk of down-time or degraded performance. Improved disk drive and RAID handling routines SNAZ Manager now provides clear identification of disk location within a SNAZ enclosure to ensure that the correct disk drive is withdrawn during maintenance. Logging of events has been improved. SMTP event notification added- up to 5 targets Remote Log-in uses SSH. Page 2 of 5

3 DATA PROTECTION Backup Powerful built in backup utility Substantially extended tape drive, autoloader and library compatibility Configurable as a BakBone NetVault client. BakBone NetVault v7.1 backup software is integrated into the SNAZ systems providing enterprise calibre backup facility for the SNAZ and SNAZ Expansion. Integrated BakBone NetVault utility supports a wide range of tape drives, autoloaders and libraries up to 4 tapes drives and 12 cartridge slots Can be integrated into an existing BakBone NetVault domain with the SNAZ system acting as a Client to another NetVault Master Backup Server. Snapshot Improved management and scheduling of snapshots. Snapshot limitations Up to 5 snapshots may be scheduled. Up to 4 Snapshots are retained. The oldest snapshot is overwritten by the new snapshot. Replication Replication capability extended Replication limitations Configurable replication account and replication logging Replication is limited to the number of file details which can be stored in memory during replication, on 1GB of SNAZ memory, this limit is ~6 million files. Only 256 directories / file lists can be replicated and only 256 subdirectories can be specified to be excluded. Product Capabilities - Known Issues and Product Notes Capabilities 2TB RAID Support Max number of Shares Max number of concurrent connections Max Active-Directory User population Max Local SNAZ-managed User population Max number of groups Max number of file system objects Max file size Details: SNAZ v4 supports Logical Volumes up to 2TB. Multiple 2TB volumes are supported. Extended addressing to support volumes up to 16TB will be released in a future enhancement. RAID-5 is default factory installed configuration with RAID-0 and RAID-1available for field configuration. RAID-10 is supported for legacy systems only. Combination of up to 40 NFS, CIFS/SMB, FTP shares. Folders may only be shared once. NFS and/or CIFS up to total of 200 concurrent connections. 10,000 users 1,000 users 100 groups Verified up to 100 million objects Verified up to 10GB files. Page 3 of 5

4 Known Issues: SNAZ Manager Dropdown Lists Tool Tips may be partially hidden behind other elements NFS Access is slow from Windows NFS Share name in Windows XP No Access to Child Domain Users Details and Workaround: When using IE6 to access certain SNAZ Manager screens, a very small number of Drop-down-lists and Tool Tips may be partially hidden behind other elements of the GUI page. This is a recognised MS Internet Explorer limitation/bug. We anticipate that this will probably be resolved in the next major release of Microsoft Internet Explorer. It does not occur in other browsers such as Firefox. Although UNIX / Linux files in a NFS share may be accessed by Windows clients, the access is at a modest speed. This is primarily constrained by the slow speed of the client s Windows Services for Unix (SFU) rather than the NAS system. We recommend that Windows file sharing is primarily provided by CIFS /SMB shares to achieve maximum speed. A feature Windows Services for Unix (SFU) is to display the SNAZ Machine Name as a Share name when connecting to NFS Shares. To access a user list from a different domain, the other domain must have the Restrict Anonymous setting turned off. Find the registry key HKLM\SYSTEM\CurrentControlSet\Control\Lsa Add the following DWORD key RestrictAnonymous and set it to 0 Unable to delete failed independent RAIDs BakBone NetVault Version Conflict NetVault Database Back-up of ACL s Search for Restrict Anonymous on the Microsoft website for more information about this registry setting. Each disk drive in a RAID contains information about the RAID. If a disk is taken off-line for any reason, and while the disk is off-line you delete the RAID, the information about the RAID still remains on the disk(s)s that were off-line at the time of the deletion. If those disk(s) then come back on-line, then the RAID information they still contain is shown as independent RAIDs. These RAIDs can be removed by clicking the delete button on the RAID s details screen for each RAID. TheNetVault version 7.4 currently available on BakBone website is not compatible with the version 7.1 shipped with SNAZ. When installing the NetVault Management GUI, please use the installer found on the SNAZ OS v4.00 Software and User Documentation CD. The NetVault database is pre-allocated 1.5GB. Based on running a daily backup of 100,000 files and 2,000 directories, the DB could be 2-3GB after 12 months.. It is therefore important to specify a limited Backup Life so that the NetVault DB is kept to a manageable size. If the database runs out of space then backups will fail to run. If the NetVault Database does need to grow beyond 1.5GB, then the DB can be moved to a larger location. Contact Plasmon Support for further information about how to make this re-location > support@plasmon.co.uk. NetVault does not currently support the backup of file system ACLs. The Administrator is required to reset the ACLs on restored files Page 4 of 5
