  DISK SPEED2.0 & PERFORMANCE - PT1 A. BACKGROUND - DISKS, CONTAINERS & VIRTUAL MACHINES 1) Before we get to discussing Disk Speed... If you havent studied the virtualization craze you might or might not know a few facts which we are including here...and if you have skip to sections B+. 2) What is a Hypervisor A Hypervisor takes a large physical computer with compute resources (system board, memory, cpu sockets, socket processors, and processor cores per processor) and divides these resources so that individual parts of their platform can be made available to sub-containers, or sub-machines which operate below the physical hardware. So for example if you have 100GB of RAM, you can offer sub-machines 10-25GB of RAM for their processes.  Usually Hypervisors run as part of the Operating system, and take the remainder of the physical platform's hardware and makes that available to sub-resources. On a Mac Server, usually it can operate with 4GB of RAM, and a 50GB disk, any ...

ADVENTURES IN VIRTUALIZATION TECHNOLOGY  January 8th, 2022 STEP1 - What is this Virtualization stuff all about? 2013/2014 We were sitting down in Florida in 2013/2014 and when we arrived we were blessed with an HP AMD Server which was at the time about 5-10 years old. But it was designed as a server and had an advanced BIOS which supported AMD's MP platform. It was running windows 7 ultimate which is an incredible operating system. It had a 500GB drive, which was sufficient to repartition, and play with a bit, but other than we were bored we had no reason to touch the machine. It ran MS-OFFICE and played on the internet, and the BIOS actually had VMX disabled, or at least the AMD version of VT architecture disabled. We wanted to look at server 2012 so we shrunk the C, partition, dropped in new volume, and installed Windows Server 2012 on the new partition. And since Linux was the craze, we decided to see what it looked like, so we installed VMWARE Desktop, which applies these stran...

  Updated - 1/8/2022 Runing MACOS on old MACs (2007/2008ish) In general Apple is support High Sahara(10.13) with relatively recent 2021 security patches. This release is nearly universal and runs on iMAC's in the 2008/2009 range, as well as MacPro's in the 3.1 release cycle. Keeping security patches on MAC's is important simply because Apple identifies all the bugs they found in older OS's and dont patch them so hackers have a roadmap to access your computer. Although we have found El Capitan the FASTEST MACOS by a significant margin, it only has security patches through the fall of 2019, almost 2 years without a fix. Thats still pretty good, but installing El Capitan first, and then upgrading to High Sahara is our recommendation. It usually takes all of your changes without a blip. Mojave Release (10.14) Adds a bunch of new features, the most important is native NTFS file support for mixed computers. This allows you to read volumes created from Bootcamp, and other tool...

  HYPERV IS NOT A TYPE1 HYPERVISOR .... BUT IT COULD BE Well this is going to be a short post, but I see hundreds of Youtube Videos on HyperV being a Type1 hypervisor versus its competitors as the reason to use it.... this is HOGWASH.....why? The difference between a Type1 Hypervisor and a Type2 Hypervisor is whether the Hypervisor has COMPLETE CONTROL OF ALL HARDWARE RESOURCES..... Windows HyperV does not have the all of the resources on a Windows Desktop(Windows10 supports Hypervisor) or a Windows Server, you can load regular services on it including a Webserver, and a SQL server with limited reduction in resources to the Hypervisor. Furthermore base Windows services load on all Windows platforms which are independent. Out of the box without modification, HyperV on Windows Server or Windows Workstation is no different that Virtual Box on Windows Server, or Vmware Workstation on Windows. Its just another service running on the core Windows server... a very cool one we agree, but t...

  FIRST THE BAD NEWS.... DOMAIN CONTROLLERS STILL SUCK 20 YEARS LATER Between ourselves we have been debating the future of Windows Server which keeps growing, and requiring larger and larger number of resources... rather than simply performing better on new hardware to a level of acceptability. The general problem is that you need Domain Controllers to authenticate users and applications, and they used to consume a 486 processor at 85-90%, but we are 20 years later they are still cratering quad core servers running at 2.6Ghz and higher....we dont understand but we are starting to think that its intentional to support their Hardware manufacturer's who sell 90% of their product. But buy new hardware and install Windows 7 and you cant believe how good it is... whats the trade off you tell me? Or Maybe we just punt... and run Windows Domain Controllers on Linux which STILL RUN UNDER 1G OF MEMORY, and even run on Rasberry Pi's?  OUR ANSWER: Nadella... you need to replace Bill's...
