Major Software Update for Sun Storage 7000 Series Appliances March 9, 2010,
Volume 145, Issue 2
contains numerous and compelling features and bug fixes
Is the 2010.02 release of the Sun Unified Storage System imminent, asks Joerg Moellenkamp after stumbling upon the wikis.sun.com page that offers release notes for the 2010.Q1.0.0 expected major software update for the Sun Storage 7000 series appliances. Although it was not yet downloadable for the public at the time of this writing, the software update promises to support the Sun Storage 7110, 7210, 7310, 7410, and 7000 Simulator.
According to the advanced release notes, and Moellenkamp's features of interest, key changes are to include:
Fibre Channel: Appliances that are equipped with the optional fibre channel adapter will be able to share LUNs via FC.
iSER/SRP: Two InfiniBand block protocols, iSER and SRP, will be supported. iSER is managed like iSCSi, where SRP is managed more like FC.
Kerberized NFS: To be supported, with operating modes ranging from mere end-user authentication through data tamper-proofing and complete privacy.
Volume Shadow Copy Service (VSS) block target provider: Expect a plugin for the Windows VSS service, allowing LUN snapshots to be coordinated with applications to assure data consistency.
CIFS access-based enumeration: A new share property will be added that permits users to see only those CIFS files to which they have access, allowing users in many-client environments with shallow directory hierarchies to not be overwhelmed with files that they cannot access.
Multi-interface iSCSI targets: iSCSI targets will be optionally associated with multiple interfaces, allowing for better integration with some multipath initiators.
Deduplication: The appliance will optionally support deduplication, allowing duplicate blocks that are logically separate to share underlying storage.
Multiple pool support: The appliance is expected to support multiple pools in order to better support large, multi-tenancy environments.
Improved remote replication: Improvements are expected to include optional SSL, per-action throughput-throttling, the ability to export replicated data read-only, the ability to modify target-side properties independently of source-side properties, share-level replication (not just project-level replication), dynamic disabling of remote replication - either in toto or by action.
Microsoft interoperability enhancements: Such as identity mapping for Unix (IDMU) that consumes annotations from Microsoft Services for Unix (SFU), allowing for directory-based mappings of Windows users; all CIFS service properties will now be exposed via CIFS service configuration; and the nomenclature of directory ACL configuration is to be changed to match the expectations of Windows administrators.
AD LDAP signing: Expected support of signed communication with the domain controller, allowing the appliance to operate in Active Directory environments that require such signed communication.
Software features expected with this update contain network alerts, dynamically disabled interfaces, alertable workflows, and indestructible shares.
Additionally, a number of bug fixes are anticipated with significant improvements in clustering, remote replication, and shadow migration.
