		<description><![CDATA[Thanks to the efforts of Ryan Kernan we have an updated ZFS replication and snapshot rollup script. Ryan&#8217;s OpenIdiana/Solaris/Illumos community contribution improves  the script to allow for a more dynamic source to target pool replication and changes the shapshot retention method to a specific number of snapshots rather than a Grandfather Father Son method. 
zfs-replication.sh

Mike

		<description><![CDATA[Months of silence from Oracle on any official statement about OpenSolaris support and development have passed. With that inaction the OpenSolaris Governing Board has motioned to disband and has passed this motion. This now leaves Oracle alone with its not so open &#8220;Open Source&#8221; operating system. Unfortunately this inaction does not follow Larry Ellison&#8217;s public [...]]]></description>

It&#8217;s an excellent development project which initially is working toward delivering a compatible, fully open sourced version of the closed OpenSolaris binaries.  At first I thought this was going to [...]]]></description>

		<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>

However there are some serious problems that can occur if we do not carefully architect snapshot based storage infrastructures. This blog entry will discuss some of the issues with data noise induction and data integrity when using point in time [...]]]></description>

		<description><![CDATA[Connecting VMware iSCSI sessions to COMSTAR or any iSCSI target provider securely is required to maintain a reliable system. Without some level of initiator to target connection gate keeping we will eventually encounter a security event. This can happen from a variety of sources, for example a non-cluster aware OS can connect to an unsecured VMware shared storage LUN and cause severe damage [...]]]></description>
