The definitive guide to UCS and the Ciscor Data Center Server: planning, architecture, components, deployment, and benefits With its new Unified Computing System (UCS) family of products, Cisco has introduced a fundamentally new vision for data center computing: one that reduces ownership cost, improves agility, and radically simplifies management. In this book, three Cisco insiders thoroughly explain UCS, and offer practical insights for IT professionals and decision-makers who are evaluating or implementing it. The authors establish the context for UCS by discussing the implications of virtualization, unified I/O, large memories and other key technologies, and showing how trends like cloud computing and green IT will drive the next-generation data center. Next, they take a closer look at the evolution of server CPU, memory, and I/O subsystems, covering advances such as the Intelr XEONr 5500, 5600, 7500, DDR3 memory, and unified I/O over 10 Gbps Ethernet. Building on these fundamentals, the authors then discuss UCS in detail, showing how it systematically overcomes key limitations of current data center environments. They review UCS features, components, and architecture, and demonstrate how it can improve data center performance, reliability, simplicity, flexibility, and energy efficiency. Along the way, they offer realistic planning, installation, and migration guidance: everything decision-makers and technical implementers need to gain maximum value from UCS — now, and for years to come.

    roadmap for planning a data center

    From this 2010 book, you can see detailed descriptions of how data centers have evolved in the last 10 years and, more importantly to some readers, upcoming hardware abilities for the next 2 or so years. The latter projections may be the best aspect of the book, as it lets you intelligently plan what should go into your data center. The hardware specs come from key players like Intel, Broadcom, Emulex and Cisco.

    Chapter 2 on server architecture is a good quick summary of common hardware in this field. For example, it furnishes ready explanations of memory boards like DDR, DDR2 and DDR3, along with UDIMM and RDIMM.. While the equivalent of UDIMM existed some 15 years ago, the other types have come into being in the interim and reflect the continual [and hopefully continuing] massive increases in chip capacity engendered by Moore's Law.

    The book lays out the Intel Westmere hardware. Most impressive in many ways. Including the ability to do in hardware the Advanced Encryption Standard [AES], which far outstrips a software implementation. Plus the hardware AES is presumably safer than an incorrect or subverted software AES.

    Also, Westmere has the Trusted Execution Technology, which can prevent insertion of a feral rootkit hypervisor in place of the legitimate hardware Virtual Memory Monitor. Important because the book emphasises in many places the need and use of virtualisation in a data center to improve hardware usage. But the still increasing use of virtualisation can also be expected to lead to attacks against it. Hence Intel's preemptive moves in Westmere are welcome news.

    The book cleaves into 2 de facto parts. The first deals with topics like those mentioned above, where Intel is the most significant vendor. While the second part concerns more directly Cisco's UCS. The latter is an integration of the items in the first part with Cisco's custom hardware.

    One quibble I do have is the cluttering of the narrative with copyright symbols. Do we really need to see a copyright next to every instance of "Intel"? An improvement would have been to do what is commonly done in other books of this ilk, where the copyrights are factored out into the copyright page and possibly an introductory section.

    Nice symilies! Great work on the story. To Starry Night: I believe the meing the word "prologue" means before the story. Prologues shouldn't be just another ordinary chapter, prologues tell what happens before the main story, even if it's years back. :\

    Starry ✧ Night

    Work on your INTRODUCTIONS. Your prologue had nothing to do with your story, because nobody cares about a boy being born, just to skip a decade and begin a teenager life. It's unneeded. I also recommend that you scroll all the way up and read your chapter at least two times, fixing any mistakes you find.

    Untold Centuries Ch 1

    Hiii!!! Please like and comment!!! <p> Gilraen, was different. He knew it to. For one thing his father was the most famous Drian in Skyworld other than the Elders. It was even rumored that he was more famous. He had, after all killed Sharkan. That was a good different, a difference Gilraen liked. The biggest difference, the one he didnt like, was his hair. It was bright, fiery red. It contrasted with the white hair of the other Drians and made him stick out like a drop of blood on freshly fallen snow. It also made him the object of much teasing from the younger Drians. The older ones didnt say anything but he could feel their stares boring into his back, and could just imagine what they were thinking,* just look at that Drian. He has red hair. I've never seen anything like it. What a weirdo.* His mother, Talia was sympathetic of course, but there was really nothing she could do. His father told him to keep his chin up and not worry about what other people think. So Gilraen had to go on with the teasing and staring. *Maybe today will be different* he said to himself. The same thing he told himself everyday as he walked to The Guardroom to recieve his Messenger duty for the day. But he knew it wasnt. Sure enough, when he entered the building all heads turned to him and the conversation died. His ears burning, he stood awkwardly waiting. Conversation started back up again and the adults ignored him. He saw two boys whispering to each other, snickering and pointing at him. He knew them, Nero and Ringar the meanest boys Gilraen knew. They were the main source of his torment. "So," said Nero swaggering up to him" whats in the bag?" Gilraen held the bag that contained his lunch closer to his chest,"N-nothing." He stammered. "We'll see about that." Said Nero grabbing the bag,"see ya" he said walking back to where Ringar was standing. They laughed again. Gilraen sighed,he had known exactly what they were going to do. They did it every day. And every day the adults ignored what went on as if it never even happened. <p> Hope you liked it!! Ps l need boy names. Not character apps just names.

    UCS technologies presented in a way that is understandable and free of buzz words.

    I just finished with the first Cisco Press book that covers the new UCS architecture. I found it to be a great source for information not only on the UCS but also how we got to this point. Its detailed review of previous data center and server architectures served as a good refresher to my old repressed knowledge. Where this book really shines is in the way it explains technologies that to me seems like buzz/market speak, and providing a clear view of their value. One example of this for me is the VNLink section. I had seen it in numerous PDFs and presentations, but this book finally made me understand the value of it. If you are a consultant like me, you will find this books review of all the elements that make up a UCS solution invaluable as a desk reference. It reviews almost every part number and details out reason to use each one. The book concludes with an excellent review of UCS Manager and the 3rd party products that it ties into or integrates with and how to plan your first UCS project. The only part I wished was covered in more detail in the book is how UCS and VMWare should be architected together. You will not be disappointed with your purchase of this book.
