Announcing Release 2.0.0 of Oracle VM Storage Connect Plug-in for Oracle ZFS Storage Appliance

Oracle ZFS Storage Appliance team released the new 2.0.0 version of the Oracle VM Storage Connect plug-in, which includes the following new features since the previous 1.0.3 release. 

  • iSCSI Multipathing – Presents multiple paths between a server and Oracle ZFS Storage Appliance.
  • Multiple initiator group management – Supports LUNs presenting to multiple initiator groups, and support initiator belonging to multiple initiator groups.
  • LUNs logging into specific target groups
  • Filtering LUNs based on user credentials
  • RESTful API

The Oracle VM Storage Connect framework provides a storage discovery and provisioning API that enables the provisioning and management of storage platforms directly from within Oracle VM Manager. The abstraction provided by the Storage Connect framework allows administrators to perform provisioning operations without the need to know the specific behavior of any storage platforms that are being used within the Oracle VM infrastructure. The Storage Connect API allows third party storage vendors to develop their own Oracle VM Storage Connect plug-ins that enable their storage appliances to interface with the Storage Connect framework.

The new plug-in works with Oracle VM 3.2.x and 3.3.x. To download the software and read the documentation, visit

Friday Tips #11

Earlier this week, Oracle hosted a really cool event, the Virtual SysAdmin Day. If you missed it and happen to be in EMEA (or willing to stay up late in other parts of the world!), you can join the next one we're having on January 29th. You can learn all about Oracle Solaris, Oracle VM, and Oracle Linux straight from the experts here at Oracle.

During the event, one of the audience members tweeted a question about Oracle storage. We asked if we could use the question for our Friday tips series and he graciously agreed. Storage has a huge impact on the performance and cost of virtualization (both server and desktop) deployments, so we thought a short definition of Oracle optimized storage and the Oracle's Sun ZFS Storage Appliance would be in order.

Question:
What exactly is this ZFS Storage Appliance? Is it just a simulator or actual usable production appliance? 

Answer by Christopher J. Martin,  Principal Product Manager, Oracle Optimized Solutions:
The Sun ZFS Storage Appliance is Oracle’s preferred NAS storage system with unified storage capability for enterprise tier 1 environments that also simultaneously provides superior Block SAN features and performance. It offers a rich set of enterprise-class data services such as snapshots, clones and replication(local and remote) as well as industry-leading performance, and Oracle Hybrid Columnar Compression- a feature for Oracle Databases.  These systems also feature a comprehensive and intuitive user interface and storage analytics environment that is unmatched in the industry in terms of its ease of use and simplicity.  This dramatically reduces management time and complexity, reducing operating expenses.  The Sun ZFS Storage Appliance offers compelling economics along with extreme performance and efficiency for enterprise storage. 

Thanks Chris!

We also covered storage briefly back in our second entry in this series where we had a question on linked clones.

Thanks for reading today. We'll be covering more storage topics in future tips as well as anything else you want to ask regarding Oracle virtualization. Just use #AskOracleVirtualization on Twitter and we'll try to get your question answered.

Welcome to our Friday tips series!

Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog.

Today's tip is on Storage and Oracle Virtual Desktop Infrastructure:

Question: I run Oracle Virtual Desktop Infrastructure 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache? 

Answer by John Renko, Consulting Developer, Oracle:

Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system:

set zfs:zfs_arc_min = 5368709120
set zfs:zfs_arc_max = 5368709120

The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

BriForum 2012 - Oracle Virtual Desktop Infrastructure Aligns with the Experts.

BriForum 2012 in Chicago includes great sessions from industry experts and consultants focused on VDI and Server Based Computing.   One session delivered by Ron Oglesby of Unidesk presented "How you can solve common problems with VDI".  As VDI deployments have increased in size a major challenge as been optimizing storage to deliver the IOPS required for desktop workloads.  This requirement often is in conflict with the goals of reducing the CAPEX investment of implementing VDI.

Ron Oglesby recommends the use of "Hybrid Storage Arrays" that provide a combination of large controller memory,  Solid State Disk (SSD) for high IOPS,  combined with lower cost array disks.   He then asks if anyone has heard of ZFS

When you consider this general recommendation from Ron, it aligns with the Oracle Virtual Desktop Infrastructure solution that for years has taken advantage of the Sun ZFS Storage Appliance.  Otherwise considered a "Hybrid Storage Array" that as Ron generically suggests works very well for desktop workloads.

Ron goes on to mention the option of using local storage for lowering the CAPEX cost for VDI that can provide high IOPS with the lower cost of internal disks within the hypervisor server.   Local storage is not for all deployments but can certainly be used for deployments such as flexible desktops without high availability requirements. 

The latest release of Oracle Virtual Desktop Infrastructure aligns well with this recommendation by supporting fast local storage installed on servers running the Oracle VM VirtualBox hypervisor.   The Oracle VM VirtualBox hypervisor when installed on Oracle Solaris can provide the local storage with ZFS combined with the large server memory footprint available with Oracle Servers.  Additionally, the Oracle VM VirtualBox hypervisor can be deployed onto Oracle Linux and leverage the Oracle Cluster Files System V2 (OCFS2) combined with the large memory available with Oracle Servers.

The Oracle Virtual Desktop Infrastructure strategy that leverages hardware and software optimized for delivering virtual desktop workloads clearly is lining up with recommendations from virtual desktop experts.
