ZFSSA software release 2011.1.1.0 is available, Steve Tunstall blogs. Users will need 2010.3.2.1 or greater to upgrade to 2011.1.1. This major software update contains numerous bug fixes and important firmware upgrades, Tunstall reports, then lists the various new features in the release, among which are:
Last year, Tomi Hakala wrote an article describing how to use NexentaStor to create an NFS share on a commodity x86 box and make that share available to vSphere. Those steps with version 3.0 are still the same with version 3.1:
Install NexentaStor; obtain a unique key; enter key
Create a ZFS volume
Create a folder
Configure NFS Server (use NFS v3)
Note the mount point in which folder is available to NFS client
Open vSphere Client and mount NAS datastore
NexentaStor 3.x is a major release, with many new features, improved hardware support, and many bug fixes over the older Developer Edition including:
In-line deduplication for primary storage and backup
Free for up to 18 TB of overall raw storage capacity (i.e. sum of all ("raw") disks sizes, excepting logs, caches and spares)
Supports easy upgrade to future Community Edition releases and to Enterprise Edition licenses
Support for user and group quotas
The ability to automatically expand pools
NexentaStor 3.x Community ISO CD images can be installed on "bare-metal" x86/64 hardware. VM installed images are also available.

In the sun.com post "Oracle Solaris 11 ZFS File System on Oracle Solaris 11" readers will find a multi-part hands-on tutorial on the basics of Oracle Solaris ZFS that describes how devices are used in storage pools and considers performance and availability. It also looks at the various types of Oracle Solaris ZFS datasets that can be created and when to use each type. Participants will learn about file system snapshots, cloning data, allocation limits and recovering from common errors. The exercises take participants through creating some zpools and exploring different types of virtual devices (vdevs).

By way of their slide presentation from Oracle OpenWorld 2011, now available as a download, Cheri Williams, Craig Yappert, and Gowthaman Ranganathan provide an update on Oracle IT Upgrades to Sun Storage Products. The presentation is in three parts:
Overview: Oracle IT and Storage Strategy (reasons for migrating to ZFS Storage Appliance and outline of storage strategy)
Storage Configurations and Performance (specifics of Oracle ZFS Storage Appliance)
Oracle IT Use Cases (includes an overview of ZFS Storage in Product Development)
The presentation then summarizes lessons learned from the migration to ZFS Storage Appliance.

Shadow Migration, according to Steve Tunstall, is a tool useful both for migrating data from any non-ZFSSA, NFS source or even from a different pool between controllers on the SAME clustered ZFSSA system. This is unlike the replication feature of ZFSSA, which can talk only to another 7000 system. Shadow Migration can get data from both a local source or from any NFS mount from anywhere. He then outlines an eight-step process for performing a Local Shadow Migration, moving data from a share in one pool to another pool on the same system.
