With the updated version of ITIL imminent (the 29 July 2011), I participated in a BrightTalk webinar on “what next for ITIL.”
My views on this are very clear, that we need to “look back before we look forward.” I touched on some of this in a previous blog, 2011: An ITIL Versioning Odyssey, but think it worthwhile to continue to articulate my views in this area.
Let's start with what I consider to be the biggest issue: the gulf between theory and practice with ITIL.
There is no doubt that ITIL can benefit I&O organizations. There are certainly many I&O organizations encouraging, or even forcing, their people to take ITIL training and qualifications: There are at least 1.5 million people with the certification and there is no sign of this slowing down. Not only are trainers busy, so are ITSM consultants and, of course, industry analysts. But, from an industry analyst perspective, there is a lot wrong with ITIL. This is not just how it ballooned in size from ITIL v2 to ITIL v3, but also how it is adopted in the real world.
So what's going wrong?
If you look at existing ITIL v2 adoption, there is a focus on the reactive elements such as incident management, problem management, change management, and maybe even configuration management and service-level management. How many organizations have moved on to the more proactive elements such as availability management, capacity management, IT financial management, and continual service improvement?
After considerable speculation and anticipation, VMware has finally announced vSphere 5 as part of a major cloud infrastructure launch, including vCloud Director 1.5, SRM 5 and vShield 5. From our first impressions, it is both well worth the wait and merits immediate serious consideration as an enterprise virtualization platform, particularly for existing VMware customers.
The list of features is voluminous, with at least 100 improvements, large and small, but among the features, several stand out as particularly significant as I&O professionals continue their efforts to virtualize the data center, primarily dealing with and support for both larger VMs and physical host systems, and also with the improved manageability of storage and improvements Site Recovery Manager (SRM), the remote-site HA components:
Replication improvements for Site Recovery Manager, allowing replication without SANs
Distributed Resource Scheduling (DRS) for Storage
Support for up to 1 TB of memory per VM
Support for 32 vCPUs per VM
Support for up to 160 Logical CPUs and 2 TB or RAM
New GUI to configure multicore vCPUs
Storage driven storage delivery based on the VMware-Aware Storage APIs
Improved version of the Cluster File System, VMFS5
Storage APIs – Array Integration: Thin Provisioning enabling reclaiming blocks of a thin provisioned LUN on the array when a virtual disk is deleted
Swap to SSD
2TB+ LUN support
Storage vMotion snapshot support
vNetwork Distributed Switch improvements providing improved visibility in VM traffic
vCenter Server Appliance
vCenter Solutions Manager, providing a consistent interface to configure and monitor vCenter-integrated solutions developed by VMware and third parties
Revamped VMware High Availability (HA) with Fault Domain Manager
