Download or read book IBM SAN Volume Controller 2145 DH8 Introduction and Implementation written by Jon Tate and published by IBM Redbooks. This book was released on 2015-01-22 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data is the new currency of business, the most critical asset of the modern organization. In fact, enterprises that can gain business insights from their data are twice as likely to outperform their competitors; yet, 72 percent of them have not started or are only planning big data activities. In addition, organizations often spend too much money and time managing where their data is stored. The average firm purchases 24% more storage every year, but uses less than half of the capacity it already has. A member of the IBM® Storwize® family, IBM SAN Volume Controller (SVC) Data Platform is a storage virtualization system that enables a single point of control for storage resources to help support improved business application availability and greater resource utilization. The objective is to manage storage resources in your IT infrastructure and to make sure they are used to the advantage of your business, and do it quickly, efficiently, and in real time, while avoiding increases in administrative costs. Virtualizing storage with SVC Data Platform helps make new and existing storage more effective. SVC Data Platform includes many functions traditionally deployed separately in disk systems. By including these in a virtualization system, SVC Data Platform standardizes functions across virtualized storage for greater flexibility and potentially lower costs. SVC Data Platform functions benefit all virtualized storage. For example, IBM Easy Tier® optimizes use of flash storage. And IBM Real-time CompressionTM enhances efficiency even further by enabling the storage of up to five times as much active primary data in the same physical disk space. Finally, high-performance thin provisioning helps automate provisioning. These benefits can help extend the useful life of existing storage assets, reducing costs. Integrating these functions into SVC Data Platform also means that they are designed to operate smoothly together, reducing management effort. In this IBM Redbooks® publication, we discuss the latest features and functions of the SVC 2145-DH8 and software version 7.3, implementation, architectural improvements, and Easy Tier.

Download or read book Implementing the IBM SAN Volume Controller and FlashSystem 820 written by Jon Tate and published by IBM Redbooks. This book was released on 2014-11-10 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: In today's 24 x 7 world, there is likely not a business on this planet, IBM® Smarter Planet® or not, that finds that their storage requirements are growing too fast and demand is starting to outpace supply. Not only this, but in this cost-conscious environment of today, the costs of managing this growth are likely to be eating into the IT budget. One way to make better use of existing storage without adding more complexity to the infrastructure is the IBM System Storage® SAN Volume Controller (SVC). For many years now this has helped business become more flexible, agile, and introduced an extremely efficient storage environment. SAN Volume Controller is designed to deliver the benefits of storage virtualization in environments from large enterprises to small businesses and midmarket companies. Virtualizing storage with SAN Volume Controller helps make new and existing storage more effective. SAN Volume Controller includes many functions that are traditionally deployed separately in disk systems. By including these in a virtualization system, SAN Volume Controller standardizes functions across virtualized storage for greater flexibility and potentially lower costs. Now, with IBM FlashSystemTM storage, SAN Volume Controller is enabled to extend its reach and benefit all virtualized storage. For example, IBM Easy Tier® optimizes use of flash storage. And IBM Real-time CompressionTM enhances efficiency even further by enabling the storage of up to five times as much active primary data in the same physical disk space. In this IBM Redbooks® publication, we show how to integrate the IBM FlashSystem 820 to provide storage to the SAN Volume Controller, and show how they are designed to operate seamlessly together, reducing management effort. In this book, which is aimed at pre- and post-sales support, storage administrators, and people that want to get an overview of this new and exciting technology, we show the steps required to implement the IBM FlashSystem 820 in an existing SAN Volume Controller environment. We also highlight some of the new features in SAN Volume Controller that increase performance. If you are not already familiar with the SAN Volume Controller, it is beneficial to read the following IBM Redbooks publications: - Implementing the IBM System Storage SAN Volume Controller V6.3, SG24-7933 - Implementing the IBM Storwize V7000 V6.3, SG24-7938 - Real-time Compression in SAN Volume Controller and Storwize V7000, REDP-4859 - IBM SAN Volume Controller and IBM FlashSystem 820: Best Practices and Performance Capabilities, REDP-5027 - IBM FlashSystem 710 and IBM FlashSystem 810, TIPS1002 - IBM FlashSystem 720 and IBM FlashSystem 820, TIPS1003 - Flash or SSD: Why and When to Use IBM FlashSystem, REDP-5020
