Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, (Read More)

VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

Rethinking Your Already Virtualized Low Hanging Fruit

Virtualization ManagementAt VMworld 2011, VMware presented a chart that showed their progress in terms of virtualizing various workloads in their own customer base.  The chart (shown below) demonstrated that VMware had made some really good progress with some really hard workloads, and mostly excellent progress with easy workloads (low hanging fruit). The interesting question is what is the best way to proceed from here on out. Continue reading Rethinking Your Already Virtualized Low Hanging Fruit

Unified Computing: Collective Group or Single Responsibility

DataCenterVirtualizationI have spent a great deal of time lately working with the Cisco Unified Computing System (UCS). This computing platform is really quite impressive with its power and flexibility, but my expectations about the platform have really changed since I completed the UCS training. During the training classes that I attended, both the design and install courses emphasized that the Cisco UCS platform would be a collaborative platform that would bring the different groups like Storage, Network, and Server each working their own functional area of responsibility within UCS based on role permissions.  That sounded great.  The network team can create and trunk the VLANS and the storage team could add the boot targets as well as assign the LUNS. This platform is a true collective effort by all teams right? Continue reading Unified Computing: Collective Group or Single Responsibility

Defense in Depth: Firewalls within the Virtual Environment

VirtualizationSecurityThe 6/14 Virtualization Security Podcast we spoke about firewall placement within the virtual environment as well as storage based defense in depth. While we covered Encryption on the 5/31 podcast, in the 6/14 podcast we  covered other measures when dealing with storage (which will be part of a followup post). This conversation was slightly different than all other firewall discussions, as it was about migrating from a physical environment to a virtual environment, and keeping the same firewall placements. Spurred by a customer, we sought to come to a set of guidelines to follow for defense in depth within the virtual as well as physical and hybrid cloud environments.

Defense in Depth: Encryption within the Virtual Environment

VirtualizationSecurityThe 5/31 Virtualization Security Podcast we spoke to High Cloud Security about encryption as a defense in depth, and where to place encryption within the virtual environment. This lead to an intriguing discussion about what is actually missing from current virtual environments when it comes to encryption. We can encrypt within each VM and we can encrypt within the networking fabric, as well as within the drives themselves, but currently that leaves several vulnerabilities and unencrypted locations that can be used as attack points. While we concentrated on vSphere, what we are discussing applies equally to all hypervisors. Continue reading Defense in Depth: Encryption within the Virtual Environment

Dell Storage Forum 2012: Converged Infrastructure Future

Dell_Circle_100x30At Dell Storage Forum 2012, Dell introduced a new converged infrastructure that features an Equallogic Array that takes up 2 slots of a new blade enclosure. Moving storage closer to the workloads running within the blades. This is a very interesting and powerful play by Dell, but I kept asking myself is this really a converged infrastructure? Or it is just an integrated blade enclosure that others have at this time? Continue reading Dell Storage Forum 2012: Converged Infrastructure Future

Dell Transforms Virtualization Management with Quest Buy

Dell_Circle_100x30In “Dell a Virtualization Management Leader?” posted almost a year ago, we explored how Dell might combine the product assets that it has licensed from DynamicOps (sold by Dell as VIC Creator – see the product review here). The basic idea was the monitoring of the virtualized environment would be combined with the ability of VIS Creator to dynamically provision services so that dynamically provisioned services could be offered with performance and availability assurances. The idea that Dell could bring the entire portfolio of Quest assets to bear fundamentally transforms both the notion of automated service assurance of dynamically provisioned services, and the entire systems management business.
