Reading Time: 3 minutes vStorage API Introduced for the first time in vSphere the vStorage API are specific functions to permit an integration more thight with external storage functions. Note that there also other integration module that are coverd in the PSA framework. For more information see: What Is New in VMware vSphere™ 4: Storage What’s New in VMware vSphere™ 5.0 – Storage vSphere Storage API – Storage Awareness (VASA) This is a new set of APIs introduced in vSphere 5.0 that will enable VMware vCenter Server to detect the capabilities of the storage array LUNs/datastores, making it much easier […]
Reading Time: 3 minutes The vCenter Server availability could be necessary in most cases and critical for large environment (or where a lot of services depends on it). In small environment, usually, this not so critical, because most of the VMware functions still work also without vCenter Server (for more info see vCenter Server Design: Physical vs Virtual). There are at least four solutions to increase the availability for vCenter Server: use a VM for vCenter Server and use VMware HA use vCenter Server Heartbeat product use a MSCS solution for vCenter (unsupported from vSphere version) use VMware FT […]
Reading Time: < 1 minute From the version VI 3.x the vCenter Server can be deployed or on a physical server or on a virtual machine (both solutions are supported by VMware). In this page pros and cons are analyzed.
Reading Time: < 1 minute Note: VMware has removed the vRAM Entitlements concept and restriction. So this post is no more relevent! Introduced during the official announce of vSphere 5, this news in the vSphere licensing (expecially for the hosts) has been changed (the first rumor of this was mentioned here by Gabrie van Zanten). Not in the priciple (the vRAM is still the allocated vRAM of powered on VM, not the consumed vRAM) but in his value and how are counted (for example there is a max vRAM value of 96 GB for each VM): vSphere edition Previous vRAM […]

Identify available vSphere editions and features (some changes from vSphere 4.x) See the Compare vSphere 5.0 Kits and Compare vSphere 5.0 Editions. Explain ESXi and vCenter Server architectures (similar as vSphere 4.x) See the VMware Sphere Basic guide, the Objective 0.1 – VMware Products and also VMware Web Site. Explain Private/Public/Hybrid cloud concepts See the Objective 0.2 – Cloud Concepts. Determine appropriate vSphere edition based on […]
Reading Time: < 1 minute In vSphere 5, for the first time, ESXi has now an integrated firewall. In this way another feature gap between ESXi and ESX has been filled. But this firewall is quite new and different compared to the one from ESX, although the management (at the GUI mode) remain similar of the old one. For more info see: http://vinfrastructure.it/vdesign/esxi-5-firewall/
Reading Time: < 1 minute On the VMware site there are new version of the VCP blueprint, both for VCP4 and VCP5: VCP410 Exam Blueprint Guide 1.9.2 VCP511 Exam Blueprint Guide 1.4 About the VCP5 document, still i cover the beta exam and it does not make any changes in the covered objectives. My version with study notes is still a work in progress.
Reading Time: < 1 minute With vSphere 5 now there are two diffent clients GUI oriented to manage vSphere: the traditional vSphere Client (to be installed on a Windows OS) the new client web-oriented: vSphere Web Client. To work correctly this client require a server part (that is already included in the vCSA and must be installed in the Windows version of vCenter). In this page let’s talk about the pros, cons and limits of the vSphere Web Client.
Reading Time: < 1 minute With vSphere 5 there is a new version of vCenter Server: VMware vCenter Server Virtual Appliance. In this page we will see pros and cons of the VA compared to the installable version.
