I’ve never paid too much attention to the different types of RAM (Random Access Memory) during my tenure as a Systems Engineer but wonder how much time it would have saved me in troubleshooting. This post is not only an attempt to educate other technicians, but an opportunity to refine my own knowledge of the subject. There are three main categories that I want to review. Ecc vs Non-ECC, Unbuffered vs Registered memory, and Memory Rank. ...
I recently purchased a Synology DS411slim NAS device for my home lab in order to quiet down my rack and start using up less power. Obviously to accomplish this I would need to fill it up with Solid State drives which have the added benefit of a large number of IOPS :) I screwed my four 480GB OCZ SSD’s into the drive cages and slipped them into the chassis. Really my only con for this device was getting the drives into the chassis. I did have to do a bit of wiggling to get them seated correctly. ...
This post was a direct result of a request from one of my readers. I hope that this post will explain VMware networks a bit more and how they fit into a production network. To begin I’d like to review how a VMware ESXi server might have its virtual switches and port groups setup to connect to a physical switch. Here is a list of networks that we’ll be working with. ...
I was recently interviewed by Andrew McCaskey from SDR News about the HP Discover conference. The interview is below http://www.youtube.com/watch?feature=player_detailpage&v=IUM-sDiHD18
A few months ago there was an annual vote to determine the top 50 virtualization bloggers according to vsphere-land.com. These top 50 bloggers are then added to the vLaunchPad where they will remain cataloged for a year until the next year’s voting. Kudos to Eric Siebert for running this whole process! TheITHollow.com was lucky enough to make the top 50 in it’s first year of existence and to celebrate I asked my good friends (well, family really) over at www.whateverinspires.com to create a top 50 badge to put on my site. They were happy to oblige and even created a top 25 and also a top 10. ...
Only a few years removed from when HP announced they were ditching the workstation part of their product line, they’ve announced a new set of desktops this week. The EliteOne 800 G1 The EliteOne 800 G1 is an all in one solution for companies that include the newer Intel 8 Series Q85 chipset which includes the Intel vPro technology. I haven’t been able to get my hands on playing with this yet, but essentially it uses the trusted execution environment in order to allow access to the PC even if it’s powered off, or if it has a virus. Perhaps this doesn’t seem like a big deal to end users, but the IT group that has to support these devices will certainly take notice. I liken it to having an iLO processor on every desktop so that troubleshooting can be done remotely by support. This will even allow off site or third party support to gain access in order to troubleshoot issues. ...
HP has a new MicroServer out that would be perfect for the anyone who is looking for a solid home lab server. The Microserver G7 was a fairly popular server for home computing enthusiasts and HP decided to add upon that line. The original reason for this server was for small businesses that wanted a small but stable server with features such as integrated Lights Out (iLO) but as it so happens, this line was pretty useful for those bloggers and certification junkies that wanted to take some HP Servers home with them. ...
HP officially announced the new HP 3PAR StoreServ 7450 today to some oohs and ahhs at HP Discover. The new 3PAR is an all flash array that can be utilized for small, medium or large business needs. HP is touting that some of their competitors are having difficulty with the flash hurdle because their systems were optimized for spinning disks. And other competitors who designed their arrays specifically with flash in mind from the ground up are not proven arrays from a reliability standpoint. ...
I want to address a concern that many HP Virtual Connect customers have had about monitoring their Blade Chassis. A question I’ve received was “How do I know if I have sufficient uplinks for my traffic?” Depending on the size of the organization and their familiarity with their networking equipment, they could be monitoring the available metrics on their switches. If they are not necessarily that network savvy or don’t have the proper monitoring tools in place, they can use the throughput statistics tools within Virtual Connect. These tools only give a simplistic view to the amount of traffic that is going across your uplinks, and doesn’t show the traffic going out each blade but it does get you some great high level information. ...
Once per year VMware takes time to present the VMware vExpert distinction to members of the community Evangelizing, teaching, helping and speaking about VMware techniques. The annual VMware vExpert title is given to individuals who have significantly contributed to the community of VMware users over the past year. The title is awarded to individuals (not employers) for their commitment to sharing their knowledge and passion for VMware technology above and beyond their job requirements. ...
