8 Node ESXi Cluster running 60 Virtual Machines – all Running from a Single 500GBP Physical Server

I am currently presenting a follow-up to my previous vTARDIS session for the London VMware Users Group where I demonstrated a 2-node ESX cluster on cheap PC-grade hardware (ML-115g5).

The goal of this build is to create a system you can use for VCP and VCDX type study without spending thousands on normal production type hardware (see the slides at the end of this page for more info on why this is useful..) – Techhead and I have a series of joint postings in the pipeline about how to configure the environment and the best hardware to use.

s an afterthought after visiting a few recent Cloud Camp's and after talking to some very bleeding edge and clever individuals who develop applications and object based storage for the cloud I felt compelled to blog about my thoughts on this subject.

Planning for virtualization? Beware of server overload

LUN Masking at the VMkernel Level

I’ve been asked by a few customers about the location of the VMware ESX\ESXi LUN masking feature and how the LUN masking is done at the VMware ESX\ESXi level in version 4.
In VMware ESX 3.0/3.5 the settings for LUN masking were available in the UI via the Advance Software settings under Disk -> Disk.MaskLUNs as shown in screenshot below.

No matter where you look today the structure of IT is fundamentally changing. Applications are being increasingly accessed from mobile devices along with traditional laptop, desktop and even kiosk machines. Applications are downloaded for free or a few dollars on mobile devices, while cloud computing and anything as a service offers a new approach to application delivery. As a result corporate application portfolios are shifting in their mix under IT leaders from one of total control to partial to none.

Share a RAM disk via iSCSI…run VM’s from it?

  I found this very clever feature in the StarWind vSAN product that allows you to allocate a chunk of physical memory on a host (i.e real RAM) and present it out as an iSCSI target – imagine the possibilities for running virtual machines from that? watch this space \ Posted in Starwind

After a huge spike a few years ago, better power-management tools, multicore chips and advanced power supplies have helped keep temps down. But, ironically, virtualization may make things hotter again.
