Server Appliances -


disk caching  Although price/performance is good, disk quantity limitations may require customers to add a storage array. IBM For the Netfinity 4000R: Availability: These servers, although announced, are not yet available. Fuzzy focus: Although it is based on the Network Engines WebEngine (an appliance), it is unclear whether this server will be an appliance, or just a very short GP server. Network Appliance: Maintaining their NAS lead: As the field gets more crowded, it will be difficult for NetApp to maintain a Read More...

In-Memory Analytics: A Multi-Dimensional Study
The primary bottleneck to high-performance multidimensional analysis has been slow hard drive speed—the time it takes for data to be transferred from disk

disk caching  with semiconductor-based memory, while disk storage suffers the unavoidable bottleneck associated with rotation speed of magnetic disks. Low cost, high performance hardware is making it possible for enterprise software to move towards in-memory architecture. A 64-bit architecture is central to realizing the benefits of an in-memory analytics solution. In theory, 64-bit architecture supports up to 16 exabytes (EB) or 16x106 terabytes (TB); in reality, however, the actual amount of available memory is much Read More...
Informatica Morphs into Enterprise Decision Support Vendor
Informatica Corporation, long an established vendor in the Extract/Transform/Load (ETL) market space, has morphed themselves into a vendor of solutions for the

disk caching  Pipeline Processing , which combines disk staging with in-memory server-side caching to fully leverage system resources. It also has an FTP integration feature which helps set up FTP parameters for flat file transfers (flat files need to be on the same machine as the ETL server as parsing files across an NFS mount is inefficient). In addition, the product contains an open metadata repository, a pipelined, multi-threaded server engine, and a scheduling mechanism. PowerMart was followed by PowerCenter in Read More...
Riverbed and EMC Deliver Capacity-Optimized Cloud Storage for Backup, Recovery, Archiving and DR

SAP HANA-One Technology to Watch in 2012 (and Beyond)
Did you know that SAP HANA is much more than a high-speed analytic appliance? TEC principal analyst P.J. Jakovljevic reveals how HANA is a universal database

disk caching  can lead to reduced disk space requirements, memory requirements, and access times. Other advantages of columnar databases are better reporting performance, parallel data entry and processing, elimination of some aggregation types, etc. In SAP HANA, users can decide whether to configure each individual table, and more likely a range of tables, in a row or columnar organization. If users change their minds later, they can change the data organization in a table on the fly. This operation literally Read More...
How to Make Virtualized iSCSI SANs Work for You
Enterprises of all sizes are building flexible storage infrastructures by using iSCSI and virtualization technologies that let them allocate and shift storage

disk caching  Given sufficient memory and disk storage, a single hardware system running server virtualization software can support many guest virtual machines. Applications and data are processed in exactly the same way as in the physical environment, using the same operating system facilities for making system requests. The only difference is that the operating system is now a virtualized guest running in a virtual system environment. Virtual machine files can be transparently migrated from one server hardware Read More...
IBM Announces Netfinity 4000R Super-Thin Server
IBM to ship its 4000R server, a thin server targeted at ISPs and ASPs. The 4000R sets a new standard for CPU density, fitting two Pentium IIIs in a one-rack

disk caching  Announces Netfinity 4000R Super-Thin Server Event Summary On September 7th, 1999, International Business Machines Corp. (IBM) announced the Netfinity 4000R, a 1.75 - high server aimed at Internet Service Providers (ISPs) and Application Service Providers (ASPs). The 4000R, which will have up to two CPUs (Pentium II or III) per system, is a rack-mountable, stackable system. The system, expected to ship in late September, will cost $3,000 to $4,000. Market Impact This announcement sets a new level of CPU Read More...
How Do You Categorize Servers?
The term 'PC Server' encompasses a wide range of computing hardware features and functionality. So, how can the entire range be subdivided into more manageable

disk caching  box . For example, hard disk storage within the server may be minimal (just enough to hold the OS), and the server is designed to be rack-mounted with a large RAID array installed in the same rack. Examples : Netfinity 7600, ProLiant ML570, PowerEdge 6400, NetServer LH6000   Super-Enterprise: Users : Generally exceeding 500 users/clients, sometimes more than 1000 Pricing : Starts in the $20K range for basic systems, but a fully configured system, plus associated storage, memory, and options can exceed Read More...

No Back Doors. No Open Windows.
To boot or pre-boot, that is the question. There’s no doubt that operating systems (OSs) are complicated given the sheer amount of code that must be flawlessly

disk caching  can ensue. While full disk encryption (FDE) is one step closer to a more secure OS, encryption without strong authentication isn’t enough. For security-conscious users, pre-boot authentication is the only way to go. Read More...

The Marriage of Virtual Machines, Software as a Service, and Cloud Computing
New technology, such as virtual machines and high-speed internet communication, is leading to wider remote application hosting. Here is a tutorial-level

disk caching  for data entry or disk activity. Coupled with this newer technology is the availability of reliable fast large storage disks in the 500 gigabyte range. Large data stores using this disk technology are becoming common. The coming together of the high-speed global network connectivity, powerful low-cost computers with large memory capacities, and fast processors, leads to a whole new paradigm in the supply of many business services.
