What's the difference between thick- provisioned and thin- provisioned disks in ESX 4. A. Versions of ESX prior to 4. Disks in this format are created with the entire size of the disk pre- allocated on physical storage at the time the disk is created. This pre- allocation means that creating a 1. GB virtual disk actually consumes 1. GB of physical disk space on your drives. Related: Q. How can I convert a thin- provisioned disk to thick, or a thick- provisioned disk to thin, in ESX 4. Allocating physical space to virtual disks can be a resource intensive operation. The internal process that carves out disk space on your physical disk drives could have an impact on the performance of other virtual machines (VMs). Thus, pre- allocation provided a way to ensure that this resource- intensive operation occurred all at once, only when new disks were provisioned. Compare this behavior to thin- provisioned disks. With a thin- provisioned disk, the amount of physical disk storage used by a virtual disk is equal to the amount of actual data on that disk. If you create a 1. GB disk but only use 2. GB of that disk, the actual disk consumption on your physical drives will be 2. GB. There are two downsides to thin provisioning. First, each expansion of the requires a small amount of extra resources to accomplish. ![]() ![]() ![]() Windows 3.1x/95/98/NT/2000/ME/XP/2003/Vista/2008/7/8/8.1/2012 Power Toys + Tweaking Tools Your expert guide to today's tech.

Windows 7 vs Windows Vista Windows 7 is the latest operating system that has come from Microsoft. It has garnered some rave reviews from most users due in part to how. This activity can have a slight impact on disk performance, particularly when many VMs share the same Datastore. Second, administrators must pay careful attention to disk consumption. Because every disk . The result of filling up your disks in this manner can be painful at best. Today’s improvements to disks, SANs, and disk provisioning have reduced the performance impact of thin provisioning. Thus, using thin- provisioned disks can dramatically reduce your wasted disk space. However, you must be exceptionally careful to never fill that disk space to capacity. ![]() Monitoring disk space usage and having extra disks on hand in an emergency are vitally important.

Key Difference: Windows 7 and Windows XP are two operating systems that are offered by Microsoft for running on their PCs and Laptops. Windows 7 offers a new layout. Ever since Microsoft announced that the upcoming update to Windows 8 will be called as Windows 8.1 and will be available for free to all Windows 8 users, many users. ![]() Boot Process and BCDEdit. To address the increasing diversity and complexity of modern firmware and hardware, the Windows Server. It uses a new data store for boot configuration data (the BCD store) that replaces Boot. Windows. When a computer is turned on, it must perform a variety of tasks before it is ready to start running applications. To accomplish these tasks, the computer runs startup software that resides in the firmware. This software (a . The boot loader is typically independent of a specific operating system, but it can locate the code to start the next step, which is the operating system–specific phase of system startup. The boot loader and related boot configuration information is often stored in system files that are separate from the operating system, application programs, and user data. To change the boot configuration, start the boot configuration application BCDEdit. Be aware that changing the boot configuration can make the system unable to start. To avoid problems with this, make a backup copy of the current boot configuration ahead of time by using the bcdedit /export save- bcd command. The Windows Server 2. Support for both BIOS and UEFI firmware. New boot applications. New data store that replaces Boot. UEFI is the next generation of firmware architecture that is designed to replace the BIOS architecture. The new Windows boot environment is designed for both BIOS and UEFI and uses a common data store that can exchange boot configuration information between the firmware, the boot loader, and boot applications. The functionality that was previously combined in Ntldr. Windows Boot Manager (Bootmgr. Bootmgr. efi). This application is independent of the operating system and uses the firmware to load the Windows boot loader either from a particular disk partition or over a network connection (in the case of network boot). Windows Boot Loader (Winload. Winload. efi). This application is part of the operating system and loads a specific version of Windows. It uses the firmware to load the operating system kernel and to boot critical device drivers from a local hard disk. Windows Resume (Winresume. Winresume. efi). Windows Resume finds a hibernation image and then uses the firmware to read the hibernation file into RAM and to resume the operating system from the hibernation state. The Windows boot environment also includes the Windows Memory Tester (Memdiag. Memdiag. efi). You can start this diagnostic tool from the boot manager to verify that RAM is working correctly. The Boot Configuration Data (BCD) store replaces the text- based Boot. In the BCD store, the Windows boot manager, the Windows boot loader, and other boot applications are represented as program objects (GUIDs) instead of text items. A new tool, BCDEdit. Although the data store represents each object with a GUID, some objects have alias names for common use, such as . Applications can modify boot configuration data by using a new BCD Windows Management Instrumentation (WMI) provider. You can use the standard system application Msconfig. You must run Msconfig. If you have used any deployment application tools designed for Windows XP or Windows Server 2. Boot. ini in order to configure boot options such as enabling kernel debugging or remote console, you must update the tools to use BCDEdit. BCD WMI provider before you can use them to deploy Windows Server 2.
