Cloud Data Center architecture Windows Server 2012 implementation iSCSI San diskless boot Introduction

The economic contraction caused by the financial crisis has prompted the enterprise economy to enter a new era, prompting the whole IT industry to enter a period of demand for efficiency and cost control. The budget has not increased or even slightly reduced for IT companies, but there has never been a change in support for a 24-hour x7 day operation, data growth, data protection and recovery.

So a new kind of flexible, can be pooled, rapid horizontal expansion of the 0-contact standardization of "cloud data center" has gradually become the focus of various enterprises and companies, the past calculation of load-balanced HPC computing model with the virtualization technology has gradually been widely adopted and accepted by enterprises, When the stateless virtualization layer is as flexible as the HPC MPI, the process of enterprise data Center "go Unix", "X86", "virtualization" and even "cloud" begin to enter the graceful rhythm successively.

The Fibre Channel based SAN Environment, which is well known to traditional data centers, has always served in running UNIX minicomputer systems, and with the advent of iSCSI storage protocols, the use of universal TCP/IP versatility, with the help of Wan Zhaoyi Network, DCB Lossless converged Convergence Network, The advent of iSCSI protocol uninstall cards, as more and more Windows applications are viewed as mission-critical applications, iSCSI has become a popular central storage in both large and midsize enterprises that does not lose high availability SAN solutions.

Starting with Windows Server 2012 no longer requires a storage server as a Windows Server 2008 R2, it can provide iSCSI target service ver. 3.3 and iSCSI initialization programs, the iSCSI target services for Windows Server 2012 are also very informative, and I'll introduce them in my blog sometime.

In addition, although Windows Server 2012 can support the VHDX virtual disk format, but only VHD is supported in iSCSI ver3.3, for this article, a virtual disk in the VHD format of an automated deployment or diskless boot environment is sufficient.
