The best kept secret at Sun just got even better - SAM and QFS Version 5.0 is finally here!

Version 5.0 of the Sun Storage Archive Manager (SAM) and Sun QFS is now available for purchase and download. 

This is GOOD NEWS for Sun customers already familiar with this software and for new users looking to deploy storage solutions with better ways to share, manage,  protect and preserve the sheer volume of data generated by organizations and businesses today and for the future. Managing data growth is a real problem.  I'm keeping it real when I say that no single file system or technology can solve all the problems associated with managing this growth.  

I think users will be pleased with the significant new features delivered in version 5.0 making it easier to administer and improve shared file services and archive management. This software is designed to solve the specific problems users face when sharing, managing, protecting and preserving file data in distributed environments and across different storage tiers based on business value over time.

New Feature Highlights include:

Easier Administration Features 

\*Online Grow & Shrink
FEATURE: The ability to resize a file system online.
BENEFIT: You no longer have to unmount a file system before you grow or shrink the file system.

\*Rolling Upgrades
FEATURE: The ability to upgrade software in shared environments with multiple shared clients without taking down the rest of the file system.
BENEFIT: Easily upgrade software deployed in shared environments with no downtime

\*Browser-based Management Interface Enhancements
FEATURE: New Browser-based Management interface enhancements include:
BENEFIT: Simplify your experience when configuring, managing and monitoring these file systems

Solaris Feature integration & Support 

\*Solaris Zones partitioning software support
FEATURE: Shared File system and archiving file system support for the Solaris Zones partitioning software included in Solaris Containers
BENEFIT: Shared file systems and archiving file systems can now be used in virtualized environments with Solaris Zones support.

\*Solaris SMF support
FEATURE: SMF can now be used to manage error conditions that are unique to shared and archiving file systems during initializations.
BENEFIT: This management ability enables normal system operations to continue. SMF management includes such tasks as stopping or restarting SAM-QFS daemons as needed. Error messages are written to the appropriate SMF services logs.

\*Solaris Project ID support
FEATURE: The ability to associate standard Solaris projects with these file systems.
BENEFIT : Find all the files or directories associated with a Solaris project name or project id within a given file hierarchy

Performance & Scalability Features & Enhancements 

\*Sideband MySQL Database Support
FEATURE: Improve archive performance when you search and restore files with a sideband database.
BENEFIT : Improve samfsdump performance for retrieving and restoring archive data faster than previous version of the software

More supported storage 

\*New Devices are now supported
FEATURE: The following devices are now qualified to work with Sun QFS and SAM-QFS.

--Sony CSM-20 library
--IBM and HP LT04 tape drives
--Quantum DLT-S4 tape drive
--ACSLS 7.2 and ACSLS 7.3
--Sony Super AIT tape drive
--HP SL24 and SL48 libraries
--Sun VTL and VTL 2.0 with the following drives:
--HP LT03
--IBM LT03
--STK 9940B
--STK 9840B
--STK 9840 tape drive, standard and VOLSAFE
--SL3000 library, including partitioning
--Fujitsu NML270 and NML250 libraries
--IBM 3592 700 GB tape
--STK T10KB tape drive, standard and VOLSAFE
--IBM and HP LT04 WORM
--Spectra Logic Python Series libraries (T950/380/200/120/T50/T50e) creating Archive Volume Pools.

BENEFIT: More storage devices can be supported by these file systems

Time flies when your having fun or ZFS takes storage world by storm

Wow. I can't believe a whole year has passed since my last entry. Who has time to blog? When there is so much going on. A little re-cap may be in order since my last blog about Sun's its plan to open source all of its storage software IP.

All I can say is Open Storage has taken the storage world and Sun by storm. Why all the fuss? The attention given to ZFS inside and outside Sun has been astounding. Without even trying, ZFS has catapulted from hype factor to 'must have' in Sun products in record time.

So what is it about ZFS that is better than other file systems? "Them's fighten" words to many folks that have file system expertise with other Sun file system technologies. And yet, despite its detractors and behind all the hype (it can't solve every problem users face and it's performance isn't ideal in some workloads), for most general purpose applications where you need a local file system, ZFS data integrity,  integrated volume management and FREE snapshot services outshine all the areas that will get better with time. After all ZFS is a baby in file system years.

In my view there are three fundamental things that make ZFS an ideal local file system for most users.

1. Its tightly integrated into the Solaris ecosystem

ZFS can now be the root file system choice when booting from the the Solaris OS. It is the default file system in OpenSolaris today.

2. Its dead simple to administer.

Anyone can be up and running in less than 5 minutes. This fact often gets overlooked because we'd spend alot of time talking about ZFS internals rather than the things that motivate people to change how they do things today and how file systems could be better deployed today.  The "simple factor has helped to drive ZFS adoption, new users and the largest open storage project community on record as evidenced by the growing attendance at the open storage summit held last February in San Francisco.

3. Free snapshots.

No cost to users for additional data services. This fact alone has people motivated to give ZFS and Sun storage another look whether they are considering a Sun appliance based on OpenSolaris with ZFS embedded data services or they are deploying a general purpose server for file sharing.
