Virtualization products comparison

26 June 2013
Comments off

Reading Time: 4 minutesVirtualization products comparisons are almost common, but usually are too much (single) vendor oriented and each try to bring better conclusion on its products. So it’s difficult find something that it’s really independent. Also customer experiences could be polarized by their knowledge and the experience itself, or (and this could be worst) by a better design or architecture choice. I’ve write something one year ago (see this post), but of course products change so things also change. So part is still valid and part must be updated.

PCoIP vs. Blast

Reading Time: 3 minutesI’ve already write a post with the comparison between PCoIP and RDP (PCoIP vs. RDP) and some considerations on how use each protocol in a VMware View infrastructure. Other protocols, like HP RGS (Remote Graphics Software) has been removed (from View) years ago, and protocols from other solutions (like, for example, SPICE) are not included. But now there is also the HTML5 option (Blast protocol) included with the Horizon Suite or with the Feature Pack of Horizon View (see this post on how enable it).

PCoIP vs. RDP

25 January 2013
2 comments

Reading Time: 3 minutesIn a VMware View environment usually PCoIP protocol is preferred to the RDP one due to several reasons. I don’t want to spend too much time about the latency, throughput, reactivity, user experience different between those two protocols… in most cases PCoIP is better compared to RDP. But PCoIP protocol has some limits that your have to consider in your design and mainly are described in the View Architecture Planning guide.

Recovering a lost partition table with a VMFS datastore

16 January 2013
Comments off

Reading Time: 5 minutesThere are different reason where you can you loose or corrupt your partition table of your VMFS volumes: resignature from another system (for example the backup server, if connected in SAN mode), a human mistake (datastore / delete), or maybe some storage issues. In this case usually the VMFS partition is still there and also the related data: you have “only” to rebuild the right partition table. But this could really simple if you follow the recommended practice to have only one VMFS partition on each disk. In this case you have only to build […]

How to add ESXi custom drivers using an USB key

15 January 2013
Comments off

Reading Time: 2 minutesAs written in the previous post, one common issue with recent servers of new generations is that maybe the NIC drivers are not included in the standard ESXi ISO. An if you use the vendor (or a personal) customized ISO, could be possible that during a patch update or a version upgrade you loose the drivers and the system is no working anymore. In those cases you may have an ESXi that complete his bootstrap, but without any network connectivity is not usable and could be hard to fix the missing drivers because VUM and […]

Manage an “isolated” Windows Server

11 January 2013
Comments off

Reading Time: < 1 minuteThere could some cases where you may have some Windows (Server) completely isolated from the Internet, for example in some appliances or storage solution. One interesting aspect that learn on Windows products during a DataCore training was that in this case you can have some delay in the user interface, both on the DataCore GUI, but also on the Windows one.

How a technical course must be

1 December 2012
Comments off

Reading Time: 2 minutesI’ve already completed a four full immersion days of a Dell-Compellent technical course to become a Dell Compellent Authorized Installation Professional. This was a good example on how a technical course (and it’s certification) must be. Considering that a Dell-Compellent Storage has an important part related to cabling (and design the right topologies) this course is available only in a real class (make not sense to make in a virtual mode) with la lab to permit each candidate to make it’s tasks and tests.
