Welcome to the IBM System Storage Redbooks publications blog. It features short articles and pointers to related material, as well as information about residencies.
Storage Project Leader
Characterized by its performance and reliability, the Fiber Channel Protocol (FCP) has emerged as the technology of choice for block-based storage access.
While iSCSI over Ethernet has been an option for lower-cost storage networking, the performance limitations and packet loss that are associated with Ethernet have limited the usefulness of iSCSI in demanding storage environments.
With the advent of 10 Gbps Ethernet, and the development of lossless Ethernet... [More]
For those of us that prefer a grown-up operating system for our smartphones (ok, ok, kidding, calm down you iOSites), I am certainly pleased to see that we are now able to get IBM Redbooks on the Android platform.
Naturally it took longer to port to Android as Android users are typically more demanding, intelligent, witty, good-looking, and all these had to be factored in before it was released to Google Play. I shall stop now .
Anyway, it's there now, download it, works with... [More]
I admit, it's not a very appealing title for a blog post. But it's serious matter that pertains to data security and national regulations.
The National Institute of Standards and Technology (NIST) SP 800-131A is a United States standard that defines which cryptographic algorithms are valid and which cryptographic algorithm parameter values are required to achieve a specific security strength in a specific time period.
Starting in... [More]
Secure your data with industry-standard data-at-rest encryption with no performance impact .
With the ever-growing landscape of national, state, and local regulations, industry requirements, and increased security threats, ensuring the protection of an organization’s information is a key part of operating a successful business.
Encrypting “data at rest” is a key element when addressing these concerns.
Here are a few key facts about XIV... [More]
The wait is over, the IBM Redbooks publication; Implementing IBM FlashSystem 840 , SG24-8189 is now available. The team; Marcos Figueirdo Jr., Adrian Flores, Ron Herrmann, Detlef Helmbrecht, Carsten Larsen, and Leandro Torolho, worked long hours to make this happen, with the help of the extremely knowledgeable Houston FlashSystem developers.
Read this book for practical application, and in-depth discussion of product architecture, software and hardware, its implementation,... [More]
Gen 5 Fibre Channel is the latest evolution in Storage Area Networks (SANs). Based on technology developed by the T11 technical committee that defines Fibre Channel interfaces, Gen 5 Fibre Channel doubles the data throughput of 8 Gbps links, from 800 Megabytes per second (MB/sec) to 1600 MB/sec with Gen 5 Fibre Channel.
The benefits of faster networking technology are easy to understand. Data transfers are faster, fewer links are needed to accomplish the same task, fewer devices need to be... [More]
Are you a new DFSMSrmm user? Then this IBM Redbooks publication introduces you to the DFSMSrmm basic concepts and functions. You learn how to manage your tape environment by implementing the DFSMSrmm management policies.
Are you already using DFSMSrmm? In that case, this IBM Redbooks publication provides the most up-to-date information about the new functions and enhancements introduced with the latest release of DFSMSrmm. You will find useful information for implementing these new... [More]
The IBM z/OS DFSMShsm Primer, SG24-5272 is available. The information in this publication is valid for technical storage specialists and storage administrators with the basic DFSMShsm knowledge for implementing and customizing DFSMShsm.
You can download this publication at http://www.redbooks.ibm.com/abstracts/sg245272.html?Open
This IBM Redbooks publication is written at the IBM z/OS® V1.13 level. While the current level of DFSMS is V2.1, you should use this... [More]
We have recently released a Redpaper draft that provides extensive practical information about the IBM Hyper-Scale technology available with the XIV Storage System.
The three majors components delivered with IBM Hyper-Scale are covered: Hyper-Scale Manager, Hyper-Scale Mobility and the more recently released Hyper-Scale Consistency.
IBM Hyper-Scale helps you easily overcome provisioning scenarios that normally challenge traditional... [More]
In this IBM® Redbooks® publication we introduce the IBM Storwize® V7000 Unified. Storwize V7000 Unified is a virtualized storage system designed to consolidate block and file workloads into a single storage system. Advantages include simplicity of management, reduced cost, highly scalable capacity, performance, and high availability. Storwize V7000 Unified storage also offers improved efficiency and flexibility through built-in solid-state drive (SSD) optimization, thin provisioning,... [More]
We get asked this question a lot, we know the information is out there and our friends at Google will find it for us, but if you wanted a 1 page shot of the comparisons between Storwize V3700, V5000, V7000 on one page, here it is (click on it to enlarge the image):
Well this isn't so much of a blog entry, but more of a microblogging entry as our friends at wikipedia would have us know it as.
Anyway, Barry Whyte has made some, ahem, observations about EMC XtremeIO which are well worth a read on his blog at:
I don't suppose that this offering could lead to vendor lock-in could it? Surely not.....
Prior to the version 7.2 SAN Volume Controller software release, stretched cluster configurations did not provide manual failover capability, and data being sent across a long distance link had the potential to be sent twice. The addition of 'site awareness' in version 7.2 routes I/O traffic between SVC nodes and storage controllers to optimize the data flow, and it polices I/O traffic during a failure condition to allow for a manual cluster invocation to ensure consistency.
Fabric Vision was introduced with IBM Network Advisor 12.1.x and FOS V 7.2.x. The Fabric Vision license includes support for Flow Vision, Monitoring Alerting Policy Suite (MAPS), Clear Link Diagnostic Port, Fabric Watch, and Advanced Performance Monitoring. Switches with Fabric Watch (FW) and Advanced Performance Monitoring (APM) licenses automatically get FOS V 7.2.x Fabric Vision license features simply by upgrading to FOS 7.2.x. Switches with only FW or APM can upgrade to Fabric Vision by... [More]
Well the picture is not exactly our latest Gen 5 switches, just a reminder of how far we have come since the days of personal computers with two floppy disks ! If you tell the kids of today that they just won't believe you !
Anyway, getting back on topic and in line with announcements from IBM on December 3rd, we published these IBM Redbooks Product Guides:
