Symantec Administration of Storage Foundation
Symantec Corp. upgraded its Storage foundation storage management and file gadget application these days, taking competencies of glimmer to help efficiency of DAS.
Symantec Storage foundation 6.1 contains two modern flash-related facets. bendy Storage Sharing (FSS) works interior the Storage foundation Cluster File system (CFS), the employ of server-based glimmer to permit sharing of storage across nodes with out a SAN or network-connected storage. SmartIO makes employ of glimmer to cache information on the software level, serving as a examine cache from the host. It caches scorching data on local solid-state drives (SSDs) to enhance performance and reduce latency.
Symantec additionally brought assist for crimson Hat commercial enterprise Virtualization in Storage groundwork to travel together with previous guide of VMware and Microsoft virtualization systems.
CFS is used for top availability and speedy failover for cataclysm recovery, however except version 6.1 it may only exist used with shared storage. FSS takes potential of far off direct reminiscence access assist over InfiniBand, Converged Ethernet and 10 Gigabit Ethernet to circulation applications between DAS clusters. Admins can set up clustered volumes to Run on multiple nodes. statistics on internal disks can exist exported or shared with other nodes within the cluster. If the host goes down, facts can exist accessed on an additional node in the cluster.
"DAS is coming back as a result of SSDs Make it possible," referred to Arun Balakrishnan, Symantec's manager of suggestions availability. "We're enabling a shared-nothing infrastructure. Servers can now access far flung storage as if it maintain been autochthonous storage."
Balakrishnan observed the purpose is to merit rid of the bottleneck between the server and storage array that mitigates the efficiency of glimmer in shared storage. "You nonetheless requisite to join arrays to servers [when using shared storage], and that interconnect is the bottleneck," he talked about. "Latencies are nevertheless in the millisecond range."
SmartIO controls caching at extent, file gadget and file levels, optimizing input/output for the software and back-conclusion storage. It permits software, database and server directors to stream their reads and writes inside the server.
Flash-caching application items are already regular, with most PCI categorical glimmer providers providing them with their cards. Storage carriers EMC Corp. (XtremSF) and NetApp Inc. (Flash Accel) additionally sell flash-caching utility.
Balakrishnan pointed out Symantec's caching works across any glimmer hardware. "We're no longer tied to a specific dealer, and they are able to travail with your present storage," he referred to.
Ashish Nadkarni, analysis director for storage at Framingham, Mass.-based IDC, pointed out that by using embracing DAS, Symantec is lamentable to proffer a standalone stack that may compete with different file methods.
"Symantec is aggressively relocating Storage foundation from being an enablement platform to being a standalone stack," he noted. "As a standalone stack, that you can almost build a storage solution like you would construct it the employ of purple Hat Gluster or EMC Isilon. you could purchase Symantec Storage basis as a storage platform delivering storage capabilities. Symantec has near to the conclusion that it can not exist the company that enables different americans's storage."
Nadkarni spoke of the approach is corresponding to what Symantec has achieved in backup, inserting its NetBackup and Backup Exec software functions on integrated appliances. "it's becoming more and more intricate to prevail as a application-simplest provider," he mentioned.

In this chapter you will exist introduced to the DB2 family of products that Run on the Linux, UNIX, and Windows operating systems.
This chapter is from the book
DB2 PRODUCTS and PACKAGING
In this chapter you will exist introduced to the DB2 family of products that Run on the Linux, UNIX, and Windows operating systems. This version of DB2 is often referred to as the distributed version to differentiate it from the DB2 for z/OS® version that runs on an IBM mainframe.
DB2 has the talent to store everyone kinds of electronic information. This includes traditional relational data, data encoded within XML as well as structured and unstructured binary information, documents and text in many languages, graphics, images, multimedia (audio and video), information specific to operations like engineering drawings, maps, insurance claims forms, numerical control streams, or any type of electronic information. This chapter illustrates some of the ways to access data in a DB2 database using some of the interfaces provided within the DB2 family. A description of each of the DB2 products are provided to illustrate some of DB2's features and functions.
The DB2 Data Server is an significant allotment of IBM's Information as a Service software portfolio that serves as the atomic flush for the broader IBM On demand architecture.
In figure 1-1 you can see that the IBM software portfolio has really evolved into a collection of towering value services provided by various IBM software portfolio offerings. The backbone fabric of this IBM reference architecture is the Enterprise Service Bus (ESB) that is used to facilitate communications across this rich set of services.
Figure 1-1 IBM Service Framework for an On demand business
IT Service Management is mostly provided by various Tivoli® products. The Tivoli portfolio is built around four key disciplines or pillars:
Performance and Availability
Configuration and Operations
Services from these pillars can exist used to collectively manage your entire IT framework. For example, Tivoli Storage Resource Manager services can exist used enterprise-wide to monitor and report on heterogeneous storage resources to expand storage utilization, identify and resolve potential problems, and ensure application availability through policy-based automation.
Development Services are the culmination of various Rational-based products that are built on the open source Eclipse platform. For example, Rational® ClearCase® provides source control services, and Rational Application progress empowers application developers with a rich set of services that can exist used to develop applications, Web pages, and extended custom services for implementation in a Services Oriented Architecture (SOA) or loosely coupled application framework.
Services that enable interaction are typically allotment of the Lotus® suite of products that enhance collaboration and understanding sharing across the enterprise and beyond. Products like Lotus Sametime® Connect can exist used for messaging and more.
A number of services in the framework illustrated in figure 1-1 are provided by the WebSphere® portfolio. For example, a product like WebSphere Integration Developer helps you define industry process flows in the standard industry Process Execution Language (BPEL), which are used to implement process services that in eddy champion you define, orchestrate, and automate industry policies. The Enterprise Service Bus (ESB) is provided by the WebSphere ESB product that provides your enterprise services with transformation, transport switching, and routing remediation among other services. Perhaps the most distinguished product of the WebSphere brand is the WebSphere Application Server that provides a runtime framework for J2EE®-based operations that are allotment of the Infrastructure Services component.
Finally there's the Information Services which limn the superset of the capabilities you'll learn about in this book. The specific set of services that are typically institute in this allotment of the IBM reference architecture are shown in figure 1-2.
The services shown to the birthright in figure 1-2 are hierarchical in nature. In other words, as you travail from bottom to top, the services provided become richer and more industry oriented.
For example, Master Data Management services are provided by the WebSphere Product heart and WebSphere Customer heart products. Master data are facts that picture your core industry entities: customers, suppliers, partners, products, bill of materials, employees, and so on. The discipline of Master Data Management seeks to decouple master information from individual applications spread across the enterprise and create a central, application independent, resource. The discontinuance result is a simplification of ongoing integration tasks and modern application development. This discipline addresses key issues such as data trait and consistency proactively rather than "after the fact"; for example, in a data warehouse (a lower service in this taxonomy). There is likewise a set of entity resolution services that felicitous within the Master Data Management service tier.
Business Intelligence services are provided by the DB2 Data Warehouse editions that you'll learn more about later in this chapter. Content Manager services are provided by the set of Content Management products and are used for document management, archiving, regulatory retention, and are a basis by which unstructured information (such as FAXes, video, voicemail, and so on) can exist searched and folded into the information asset.
Information Integration services seek to provide enterprises with ways to share, place, publish, cleanse, and enrich data institute in the lower-level data management services. WebSphere Federation Server and its parent WebSphere Information Server are two such products that champion implement these services.
Finally, the Data Management services tier is the foundation upon which the other services are built. IBM has a number of data servers that felicitous into this tier, including DB2, Informix®, IBM Cloudscape™, U2, and IMS™.
This book is specifically about DB2 in this service tier. Specifically, you'll learn how DB2 can provide any number of the high-value data-centric services shown in figure 1-3.
Figure 1-3 The data services provided by DB2, the focus of this book
For more information on the entire IBM software portfolio and how they are mapped to the illustrated services shown Figures 1-1 and 1-2, mention to the IBM Web site at www.ibm.com for more details.
The DB2 family of data servers executes on Windows, Linux (which can exist Run on the entire spectrum of IBM's hardware: System i™, System z™, System x™, and System p™), Solaris™ (both SPARC®-based and Intel®/AMD™-based installations), HP-UX™ (both PA-RISC™-based and Itanium-based installations), i5/OS®, VSE/VM, z/OS, and on pervasive platforms (like Windows Mobile Edition, BlueCat® Linux, Symbian®, Palm OS®, J2ME® platforms like the RIM® Blackberry®, and more).
The DB2 code basis is optimized for each platform to ensure maximum performance and integration. DB2 for Linux, UNIX, and Windows shares about a 98 percent common code basis with platform-specific optimizations at the operating system interface (OSI) flush (Figure 1-4).
Figure 1-4 The DB2 code for Linux, UNIX, and Windows is virtually the same
This means that once you've learned how to administer a DB2 for AIX system, for the most allotment you'll know how to manage DB2 for Linux or DB2 for Windows; this is the reason why there is a unique DB2 certification for everyone the distributed platforms.
DB2 for i5/OS and DB2 for z/OS are optimized for their respective environments. For example, DB2 for z/OS is based on a shared-everything disk architecture where the hardware-assisted Coupling Facility is used to serialize access to the shared disk. No such hardware exists for Linux, UNIX, and Windows, and therefore DB2 on these platforms uses a shared-nothing architecture. For this reason, administration tends to vary between these platforms (though many concepts and features are similar). However, the SQL API is 98% common to everyone the platforms where DB2 runs, allowing applications written on one platform to exist easily ported to another. This means that you can build an application on DB2 for Windows and port it effortlessly to DB2 for z/OS. If you build your application according to the SQL Reference for Cross-Platform progress handbook, your application will exist 100% portable across the DB2 family.
There are other synergies among DB2 running on Linux, UNIX, and Windows, as well as the other DB2 family members. For example, the JDBC driver used for DB2 for z/OS is exactly the identical code as is used for DB2 for Linux, UNIX, and Windows. So while there may exist variations in specific data definition language (DDL)-based tasks, the data manipulation language (DML) and client APIs are similar.
It looks like 2016 will exist the year of single-board computers, as more and more companies build everyone sorts of awesome boards inspired in some route by the Raspberry Pi movement.
