The Virtualization Practice

Storage Networking

Storage Networking focuses upon virtualizing the storage and the SAN while collapsing and simplifying the management and performance of storage. This includes the role of storage virtualization in the Software Defined Data Center, and the comparison of pooled local storage options with traditional network attached storage (NAS) and fiber channel attached storage. Covered vendors include VMware, EMC, IBM, Dell, HP, Cisco, Tintri, and Nutanix.

Who’s Who in Virtualization Management

Virtualizing business critical systems requires that a layer of virtualization management solutions be added to the virtualization platform. Virtualization management solutions in the areas of virtualization security, virtualization configuration management, virtualization service and capacity management, virtualization service and capacity management, virtualization provisioning and lifecycle management and backup and recovery should be added to the platform.

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.

I just finished writing all the content for my next book entitled VMware ESX and ESXi in the Enterprise: Planning Deployment of Virtualization Servers (2nd Edition) which continues the discussion on Dynamic Resource Load Balancing (DRLB). DRLB is the balancing of virtualized workloads across all hosts within a cluster of virtualization hosts without human intervention. This is the ultimate goal of automation with respect to virtualization and therefore the cloud. In effect, with DRLB the virtualization administrators job has been simplified to configuration and trouble shooting leaving the virtual environment to load balance work loads on its own.

Virtualizing Business Critical Apps – The Value of Real Time SAN Data

Supporting Tier 1 applications on VMware vSphere requires real time and granular response time and latency instrumentation of the virtual and physical infrastructure. Virtual Instruments Virtual Wisdom complements the instrumentation provided by VMware by providing individual transaction level visibility into the SAN layer of the virtual infrastructure.

There is nothing like fully understanding the protections inherent within your vNetwork and the Roles and Permissions you can set within the virtualization management tool suites to ensure your vNetwork is secured, audited, and monitored for issues. Just like you do now within the pNetwork. Unlike the pNetwork, the vNetwork provides a certain amount of introspection and capability that is missing from a pNetwork, and this will also help with security.

Due to what I stated during GestaltIT’s TechFieldDay, I was invited with Bas Raayman and others to discuss Secure Multi-Tenancy (SMT) in more detail with Chuck Hollis at EMC World. In addition, during one of the Keynotes SMT was renamed from Secure Multi-Tenancy to Simple Multi-Tenancy. The current Cisco VMware Netapp solution is plainly not secure. During the TechFieldDay at Cisco, Cisco even claimed “we did not think about security” when designing the initial solution. Cisco is worried about Quality of Service, I.E. Bandwidth through out the system to the disk. Furthermore, their definition of ‘Tenant’ was quite a bit different than my own. So we should first start off by defining Tenant.

Storage Networking – Time to TAP the SAN

Virtual Instruments new SANInsight TAP for the Fibre Channel SAN allows organizations to collect critical performance data on a real-time, deterministic and comprehensive basis. This will allow organizations to TAP all of their SAN ports in advance of SAN or storage array performance problems so that the foundation is in place to allow for rapid problem diagnosis and resolution.
