12 Overview

Microsoft Windows Server 2003 operating system

The Windows Server 2003 OS includes Microsoft Virtual Disk Service (VDS) and Volume Shadow Copy Service (VSS). These services allow you to manage storage array disks and volumes and to perform data backup and re HP EVA disk arrays.

The Microsoft Virtual Disk Service provides interfaces for managing storage devices. Windows Server 2003 included VDS 1.0. Windows Server 2003 R2 introduced VDS 1.1. Microsoft VDS 1.1 includes new service support DSM and M PIO multipath (per LUN) path queries and load balancing. The current HP EVA VDS Hardware Provider supports both VDS 1.0 and VDS 1.1.

The Micros Windows Ser ver 2003 included Volume Shadow Copy Service. With Windows Server 2003 SP1 additional improvements were made to VSS. These changes added the ability to import shadow copies in a cluster, include many LUNs in a single copy set, and perform shadow copy revert. The current HP EVA VSS HWP supports this version of VSS.

storation. The HP EVA Hardware Providers enable the VDS and VSS services to work with

s for querying, conﬁguring, and maintaining storage devices. The new services primarily

oft Volume Shadow Copy Service provides interfaces for performing backups and restores.

Windows Disk Management

Windows Disk Management consists of the Windows software and user interfaces that enable you to manage disks, volumes, and ﬁle systems. The user interface for disk management is included in the Computer Management tool within the Administrative Tools Control Panel.

Managem

ent applications

HP StorageWorks Fast Recovery Solution (FRS) and other third party m a nagement applications work with the Microsoft VDS and VSS services to allow you to manage array disks and volumes and to perform data backup and restoration. For more information about FRS, see the HP website.

Microsoft command line interfaces

Microsoft offers several command line utilities for use with VDS, VSS, and the HWPs. DiskPart and DiskRaid provide interfaces that enable you to script disk management tasks so you can automate conﬁguration of multiple storage disks.

The DiskPart utility, which comes standard with Windows XP and Windows Server 2003, manages disks, volumes, and partitions. Using DiskPart, you can use the command line to manage the disk array.

The DiskRaid utility, which comes with the Windows 2003 Server Resource Kit, conﬁgures hardware RAID subsystems. It works with any storage hardware that includes a VDS hardware provider, including HP arrays using the HP VDS HWP. DiskRaid has a command syntax similar to DiskPart. Note that if you display LUNs, DiskRaid shows LUNs in decimal rather than the hexadecimal numbering used in Command View.

Additionally, Microsoft makes a snapshot copy utility called Vshadow. You can use Vshadows with VSS and HWP to make and manage volume shadow copies and snapshots. See the Microsoft web site for more information.

Windows software providers

e Microsoft Software Providers (called Basic Disk Provider and Dynamic Disk Provider) interface

Th between the Windows OS, Windows applications, and disks, drives, and disk arrays. Through these software providers and VDS, Windows sees the disks, drives, and disk array volumes and performs actions such as partitioning, mounting, and manag ing the ﬁle system.

Other Windows software providers (not shown) are the in-box providers, such as the Windows Backup

ility and Windows Microsoft Software Shadow Copy Provider. These providers allow individual users

ut to back up and recover user volumes and ﬁles.

HP StorageWorks EVA Hardware Providers administration guide

HP Hardware Providers are not required in order for the Microsoft in-box or third party software providers to per form the tasks described above on the HP disk arrays. However, the HP HWPs extend the capabilities of various Windows providers and applications to do additional tasks that normally require the use of proprietary HP array management software. Such tasks include LUN and port m anagement and m ore sophisticated volume copying.

Microsoft Vir

Microsoft VDS provides a mechanism for managing volumes and logical units. Administrators can identify, conﬁgure, and monitor supported HP StorageWorks disk array volumes from the Windows Server 2003 Microsoft Management Console (MMC).

When used with HP disk arrays, VDS manages the array to make it appear like a Windows d isk for Windows applications. When you use Microsoft Mana gement Console, Windows Disk Manager and the Microsoft DiskPart or DiskRaid utility to control the array, your commands are sent to the array through VDS and the software or hardware providers.

VDS performs the following functions:

• Coordinat

• Performs binding

• Discloses hardware LUNs to software disks

• Performs c

Microsoft Volume Shadow Copy Service (VSS)

Microsoft’s VSS manages creation and maintenance of data shadow copies for backup and recovery, includingcopiesacrossmultiplevolumes. Toaccomplishthis,VSScoordinateswithHP’sFastRecovery Solution and Business Copy software or other third party business applications, ﬁle-system services, backup applications, and the storage hardware.

The shadow copies contain static copies of all ﬁles, such as databases, transaction logs, and checkpoint ﬁles. Because VSS coordinates copying, the ﬁles are copied in a deﬁned state.

Copy terminology

Understanding how Microsoft VSS terminology corresponds to standard IT industry terms for data copying makes it easier to understand what VSS does. The following paragraphs explain the terminology.

Microsoft generally refers to a VSS copy as a “volume shadow copy.” When created using HP FRS and HWP, this type of copy is a static replica of an original volume’s contents. It is keyed with a GUID to allow identiﬁcation of the parts of a s hadow copy set that span multiple volumes. Microsoft also refers to aVSScopyasa“plex.”ThistypeofcopyiscommonlyreferredtointheITindustryasa“splitmirror.”

you use an EVA array to make a s hadow copy, the array makes what is known as a “snapclone.”

When An EVA Snapclone is a complete clone copy of a speciﬁed Virtual Disk (LUN). EVA snapclones are available almost immediately. This is accomplished by creating a point-in-time copy and making it

diately available by pointing to data on the original volume while continuing to copy data to a

imme secondary volume in the background. When copying is complete, the snapclone is a static point-in-time copy of the original.

HP VDS/VSS Hardware Providers

Windows Server 2003 sees, partitions, mounts, and manages ﬁle systems on the disk array using its own software providers. HP’s Hardware Providers extend the array management capabilities of Windows and its applications to include functions normally performed using the disk array’s proprietary control software. These functions include managing disk array LUNs and ports and performing volume copy operations.

Overview

There are two HP HWP installation executables for each HP disk array model, one installation executable for VDS and one for VSS. These installation executables are different for each HP disk array model.

The HP Hardware Providers installation executables install the HWP ﬁles in your Windows Server ﬁle system. The ﬁles installed consist of special sets of HP DLLs and executables. These components extend the array management capabilities of Windows and its applications. Because they are installed separately, you can choose to install only the VDS or VSS HWP or both.

For VSS only, HP’s Business Copy (BC) application, which installs on the disk array an d is licensed in Command View, works with the VSS and the HP HWP components to enable the array to make VSS shadow copies. For functional purposes, you can think of BC as a part of the hardware providers, even though it is installed separately.

HP disk arrays

Speciﬁc HP Hardware Providers have been created to work with selected HP disk arrays. Different supporting technologies and features within the arrays result in some differences in their methods and capabilities of performing VDS/VSS tasks.

The follow Microsoft

ing examples demonstrate typical applications of the H ardware Providers when used with the

VDS, and VSS software components. Many more scenarios are possible.

VDS typical applications

The advantage of VDS and the HP VDS HWP is that they allow you to manage the HP disk array using the Windows interface. Array management tasks that would normally require the array’s proprietary management application can be done using VDS and the third party Windows management application of your choice. When you have multiple array models, this is par ticularly helpful because you c an manage all arrays from a single interface.

VSS typical applications

VSS shad purposes:

• Consistent backups of open ﬁles and applications

• Transp

• Fast recovery of ﬁles and data

Consistent backups of open ﬁles and applications

VSS captures data ﬁles from running applications by taking a snapshot of the da ta at a point in time, minimizing interruption to the applications. This process may include cooperation from the applications, which notify the operating system that they are momentarily pausing. During this time, the applications make data on the disk consistent by performing actions such as ﬂushing buffers to disk or writing data in memory to disk. The resulting backup data copies are typically temporary, maintained for some limited period of time until they a re superseded by newer copies.

Using a server conﬁgured with suitable applications together with VSS and the HP HWP, you can create shadow c enables multiple servers to make use of the same data, allowing data mining or testing on those servers. (However, shadow copies are read-only. If you need to write to a shadow copy, you must use a storage-management application that works with VDS/VSS to convert the copy to read/write.)
