Storage Area Network Essentials $85 The inside scoop on a leading-edge data storage technology The rapid growth of e-commerce and the need to have all kinds of applications operating at top speed at the same time, all on a 24/7 basis while connected to the Internet, is overwhelming traditional data storage methods. The solution? Storage Area Networks (SANs)–the data communications technology that’s expected to revolutionize distributed computing. Written by top technology experts at VERITAS Software Global Corporation, this book takes readers through all facets of storage networking, explaining how a SAN can help consolidate conventional server storage onto networks, how it makes applications highly available no matter how much data is being stored, and how this in turn makes data access and management faster and easier. System and network managers considering storage networking for their enterprises, as well as application developers and IT staff, will find invaluable advice on the design and deployment of the technology and how it works. Detailed, up-to-date coverage includes: The evolution of the technology and what is expected from SANs Killer applications for SANs Full coverage of storage networking and what it means for the enterprise’s information processing architecture Individual chapters devoted to the storage, network, and software components of storage networking Issues for implementation and adoption |

SQL Server Database: 5 Building and Maintenance Mistakes
The creation and maintenance of a SQL server database environment is no simple task. There are numerous parameters involving support, troubleshooting and design that need some consideration. Disregarding certain details or making small mistakes can really make this a difficult job.
Find out about SQL server monitor benefits.
These are 5 typical mistakes that occur in the creation and maintenance of a SQL server database environment. There are certainly more, but these are a few that you should be aware of.
1. No Plans To Backup
By failing to backup your databases fairly often you are opening yourself up for big problems. Proper backup procedures include a backup plan that 1) makes regular backups, 2) tests your ability to retrieve and restore data from backup systems, and 3) uses alternative locations other than the database server for data storage. Be sure to backup early and often. Situations where backups are unavailable are not good for anyone.
2. Utilization of Ad Hoc Queries
Stored procedures on the application level should be the only way a user can access the database. Permissions like INSERT, UPDATE, SELECT, and DELETE are usable when users are writing their on code with an Ad Hoc query. EXECUTE is the only permission allowed through stored procedures which, in turn, will lead the preservation of the data and also enhanced performance through caching and compiling. Proper SQL optimization begins with removing most or all ad hoc queries.
3. Not Enough Testing
Similar to having an inferior backup plan, putting untested code into production can open you up to some big problems. Not providing for beta and on-going testing is also a mistake. Optimum pre-production testing must mimic production environments as closely as possible. A small database meant for testing purposes probably won't scale well to a fully functional production environment. Performing tests now is always preferred over making fixes later.
Discover more advantages of SQL optimization.
4. Lack of Monitoring
You should not assume that your database is already optimized and has no issues with performance. Continuing SQL optimization will require you to constantly perform performance monitoring to be sure that all users are getting a seamless experience. Improper monitoring will pose a risk of hindering performance due to queries and applications tying up too many system resources. SQL server hardware environments and queries need to have constant monitoring and optimization to make certain that performance is as good as it can get. SQL monitors give DBAs a historical view of trend data to help them create a plan to tune the database and improve performance.
5. Insufficient Change Management Processes
Changing a stable production environment should not be done light-heartedly. They require proper planning, testing, and implementation procedures. Utilizing a process for change management will provide improved structure for changes that need to be made. Documenting how, why and when changes need to be made allows for fast reversions in instances where a change to the database didn't go as planned. Conducting the necessary pre-production testing needs to be a step in your change management procedure. Two words of advice: document everything.

24 Port 10/100 Mbps Fast Ethernet Switch - Rackmountable $57.45 24 Port 10/100 Mbps Fast Ethernet Switch - Rackmountable The MPI 24-port Fast Ethernet Switch is a professional networking switch that conforms to the IEEE802.3 10Base-T Ethernet and IEEE802.3u 100Base-TX Fast Ethernet standards. The rack-mountable, 24-port design is perfect for use as a network switch for stack of servers or as a distribution switch to a roomful of server racks. This device is designed to be mounted into a server rack, and features front panel RJ-45 LAN connections, as well as front-panel link/activity status LEDS. the switch is powered by a standard AC 3-prong equipment cable and has an on/off rocker switch on the back panel. A green LED on the front panel indicates when power is applied. Although it is designed for professional, power networking applications, installation is as simple as plugging the unit into a power source inserting Cat5/Cat5e STP or UTP cables into the ports. The switch automatically detects the use of straight (MDI) or crossover (MDIX) cables and switches the connection to whichever is needed for the connected device. Therefore any of the twenty-four ports can be connected to the upstream hub or router and the others connected to downstream servers, hubs, or other switches. This MPI network switch has an integrated 8K MAC address table and supports MAC address auto-learning and auto-aging. All ports can automatically diagnose half-/full-duplex modes and a dynamic buffer area automatically allocates to perform real-time network load balancing. The switch also examines error frames and adjusts itself as necessary to ensure reliable data packet transfers. With all speeds, connections, and functions automatically configured and supported, there is no manual configuration or setup required. Simply plug it in and start using it right away! 24 Port 10/100 Mbps Fast Ethernet Switch - Rackmountable The MPI 24-port Fast Ethernet Switch is a professional networking switch that conforms to the IEEE802.3 10Base-T Ethernet and IEEE802.3u |
