QuantaStor v2.1 enables dynamic pool expansion and virtual network support

QuantaStor version 2.1 brings a few new features and some minor fixes to 2.0 which are outlined in our official Change Log. Support for three features in particular stand out from the rest:

• Support for growing the size of a hardware RAID unit for LSI MegaRAID and Adaptec controllers.
  • With hardware RAID unit expansion you can add additional disks to an existing hardware RAID unit. In version 2 we had support for this at the software RAID level but 2.1 brings this support to the hardware level as well. Once the underlying RAID unit has grown you can do a Storage Pool Expand operation via QuantaStor Manager to complete the process.
• Support for dynamically growing and expanding QuantaStor storage pools through concatenation
  • Along with hardware RAID unit expansion you can now concatenate/append hardware RAID units to grow existing pools of storage. For example, if you have a storage pool utilizing a 10TB RAID5 hardware unit you can add to it a 8TB RAID5 hardware unit to grow your storage pool from 10TB usable to 18TB usable. The Storage Pool grow operation takes just a few seconds.
• Virtual network interfaces allowing for failover between physical interfaces.
  • Virtual network ports/interfaces can float between physical interfaces and is a key tool for being able to map your QuantaStor system into VPNs.

QuantaStor v2.0.13 with MegaRAID 9285/9265 support now available

There were a number of fixes and minor changes in QuantaStor v2.0.13 but one of the more notable changes was the addition of support for the 9285/9265 series of LSI controllers for use with our OEM edition. This latest generation of LSI controllers boast some impressive performance numbers and we were able to achieve well over 1GB/sec sustained sequential read/write performance with the previous 9280 series and the 9285 significantly improves on that.

Here's a full listing of all the changes in v2.0.13: http://wiki.osnexus.com/mediawiki/index.php/QuantaStor_Version_ChangeLog#v2.0.13.2872

Looking forward to late Q4 and into Q1 we have a number of great features on our roadmap for QuantaStor v2.1 and QuantaStor v3. This includes support for hybrid SSD caching, a jump to using the Advanced storage pool type (based on btrfs) as our default pool type, and some exciting grid management capabilities, more on that later.

QuantaStor 2.0.7 w/ Japanese Support & WAN Replication

Close on the heels of our v2.0.6 release we have an updated version of QuantaStor that's been localized to Japanese for the Japanese market. Special thanks to our premier reseller in Japan, A2Z Solution for their assistance with the localization process. Also of note in this release are some enhancements to our remote replication support so that you can replicate volumes and network shares over a WAN connection. One technical note on configuring your environment for WAN replication, be sure to open TCP ports 5151 and 22 in your firewall to your QuantaStor servers in order to allow the systems communicate. Port 22 is utilized for the data transfer and port 5151 is the port utilized by QuantaStor for SOAP based communication between the systems, both use SSL on the wire encryption.

QuantaStor v2.0.6 now available

With the release of version 2.0.6 we've made a number of enahancements and added few new features to QuantaStor, most significant of which is the support for remote replication of network shares. We've also changed the default storage pool type to be the 'Enterprise (XFS)' storage pool type rather than the 'Standard (EXT4)' pool type. The primary reason for this is XFS's effectively unlimited filesystem size but XFS also has some nice tuning parameters and defragmentation capabilities that are not presently available with EXT4. We're still moving ahead with our plans to support the 'Advanced (BTRFS)' based storage pool type which QuantaStor leverages to provide powerful snapshot capabilities and we look forward to announcing the beta of 3.0 in late October.

QuantaStor v2.0.2 adds support for Adaptec, OEM branding, and more

Today we've released a new version of QuantaStor which has a number of minor enhancements to v2.0. With this version we've finally added support for the Adaptec RAID controllers, specifically the 5405 and soon the 5805 and the newer 6xxx series. Additionally this version has improved support for all RAID controllers with improved RAID correlation logic and support for using a hardware RAID unit as the QuantaStor boot device. You'll also find a number of web interface bugs that were fixed including support for Firefox 4. Detailed change log is available here.
