		<description><![CDATA[Some time ago I found myself conceptually provisioning ESXi hosts that could transition local storage in a distributed manner within an array of hypervisors. The architectural model likens itself to an amorphous cluster of servers which share a common VM client service that self provisions shared storage to it&#8217;s parent hypervisor or even other external [...]]]></description>

NFS is definitely a very well rounded high performance file storage system and it certainly serves VMware Stores successfully over many storage products. Recently one of my subscribers asked me if there was a reason why my blogs were more centric to iSCSI. Thus the question was probing for a answer to a question many [...]]]></description>

		<description><![CDATA[Using snapshots to protect Active Directory (AD) without careful planning will most definitely end up in a complete disaster. AD is a loosely consistent distributed multi-master database and it must not be treated as a static system.  Without carefully addressing how AD works with Time Stamps, Version Stamps, Update Sequence Numbers (USNs), Globally Unique Identification numbers (GUIDs), [...]]]></description>

		<description><![CDATA[ COMSTAR is a new breed of open source storage product available to the world. What was traditionally a closed and proprietary storage capability is now available to our open source communities. With OpenSolaris and COMSTAR the ability to freely provision virtual storage services over very mature high end protocols on standard commodity server hardware is now a reality. High performance transports [...]]]></description>

I came across Brendan Gregg&#8217;s blog and found this entry http://blogs.sun.com/brendan/entry/unusual_disk_latency to be really interesting. He demonstrates how powerful Fishworks analytics really are. This is a great example of what capability Dtrace and the Fishworks application brings to the storage platform. It&#8217;s a cool demo and I encourage you to have a look at what this Open Storage product can [...]]]></description>

		<description><![CDATA[OpenSolaris, ZFS, iSCSI and VMware are a great combination for provisioning Disaster Recovery (DR) systems at exceptionally low cost. There are some fundamentally well suited features of ZFS and VMFS volumes that provide a relatively simply and very efficient recovery process for VMware hosted non-zero RPO crash consistent recovery based environments. In this weblog I will demonstrate [...]]]></description>
