New code out today- AK8.1 or 2013.1.1.0

The first minor release of code 2013.1 is now out and can be downloaded in MOS.

It is 2013.1.1.0, or AK8.1

Along with some bug fixes, it has three main new features:

Support for 2-port 16Gbs Fibre Channel HBA Target and Initiator (backup)

The drivers for supporting the 8300 Series adapters are available in 2013.1.1.0. In ZFS Storage Appliance, it supports SAN traffic at line rate, 16Gbps Fibre-Channel speeds at extremely low CPU usage with full hardware offloads.This extreme performance eliminates potential I/O bottlenecks in today's powerful multiprocessor, multicore servers.

 

Large Block Size (1M) Support

Enable support for block/record sizes bigger than 128k (256k, 512k and 1M) for filesystems or LUNS. The implementation for this includes a deferred update detailed in the Deferred Updates and Remote Replication Compatibility with Large Block/Recordsize Update sections below.

 

SPA Sync Concurrency

In order to better utilize the performance of high-speed storage devices, such as SSDs, improvements have been made to ZFS's algorithm for committing transaction groups. Specifically, the Storage Pool Allocator (SPA) sync process has been improved to parallelize some operations so that it spends a larger percentage of time writing data to the pool devices.
