Use Parallel Data Warehouse For All Your Processes

By Sherry Hatcher


Appliance-based hardware known as a Parallel Data Warehouse provides people with scaled-out, architectural possibilities. Massive Parallel Processing hardware or "MPP" provides measurable and predictable performance of larger workloads. It is then typically used for massive scale out scenarios that can accommodate up to hundreds of terabytes.

A Parallel Data Warehouse, in simple terms, must control a great number of physical servers that must each operate on their own SQL servers. To the end user, the database will look like it has only one database and table, even though it actually has many tables spread out across the entire physical server. It shows only one view of information across the entire enterprise.

The brain of the PDW manages query execution while the Meta data is stored and processed on a portion of the PDW. The end product is a state-of-the-art all-in-one hardware and software solution. Deployment, operations and management were less user-friendly in the past data warehouses.

It is easy to see numerous advantages to parallel data warehousing. Parallel data warehousing has brought to light the reality of large-scale processing in an economically favorable package. 100 times faster queries and ten times as scalable as traditional SQL server deployments, it functions at a far lower cost per terabyte.

Costs can still get up to a million dollars, so it isn't as if just anyone can get one. It comes standard with a generous amount of hardware, licensing, and processing power. Most of the packages come with storage, network, and even your own domain controller.

Many businesses process huge volumes of data already, something that is unlikely to change in the future. Looking into the future growth of business processes, the issue of how organizations will cope with large volumes of data like these must be addressed. So rather than buying entirely different software, businesses can make use of existing hardware and make the expansion much more cost effective.

Called the Parallel Data Warehouse Edition, Microsoft has recently released a new version of their SQL Server. Microsoft made headlines when it put itself out there among competitors in the area of Massive Parallel Processing (MPP) and data warehousing. Microsoft has set itself apart in this area by having a lower cost per terabyte and that its product can be used with existing and commodity hardware.

Known as "SMP," Symmetric Multi-Processing architecture on Microsoft's SQL server was all it previously offered. All CPUS storage and memory can be housed in one physical architecture this way. Other database operations on the other hand are found on the SQL server.

As of now, the Microsoft SQL Server Parallel Data Warehouse works with just two kinds of hardware; namely the HP Enterprise Data Warehouse Appliance and DELL. Know though that this SQL server cannot be bought on its own. This software does not work unless it is purchased with the previously mentioned hardware.

Parallel data warehouse training is being provided by several scalability experts so businesses can reap the rewards of owning this product. It was definitely smart and a good idea to hire scalability experts to help companies train how to use new data management and processing. This more scalable and faster product solution will undoubtedly offer a much better method to store and access data even for those that need to handle more complex requirements.
