File Fragmentation, SANs, NAS, and RAID
SANs, NAS devices, corporate servers, and high-end workstations all suffer the effects of fragmentation because of their multiple physical disk drives. This is

disk raid  of their multiple physical disk drives. This is attributed to the impact of fragmentation on the logical allocation of files and their physical distribution. The solution to this problem: implementing an automatic defragmentation software solution, together with intricate modern hardware technologies. Read More

Dell's High-End Rackmount Servers - Challenging Compaq's Wintel Dominance
Dell Computer Corporation has shaken up the PC Server market, in three years moving from the #5 US market share position to a solid #2 (and #3 worldwide) - and

disk raid  number of peripherals (usually disk drive subsystems). These servers compete primarily in the enterprise computing market space. Dell's (~15% WW market share, Q2) largest competitors are Compaq (~33%) , HP(~12%), and IBM (~16%) [Source:IDC]. The rackmount market is growing, partly due to server market growth in general, and partly due to a shift from pedestal/floor-standing/ tower servers. We estimate that rackmount servers will account for 60% of the general server market within 1-2 years (vs. 30-40% 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

Furthermore, advanced availability features including storage controller and I/O path failover are required to guarantee data access even in the case of component failure. Consideration should also be taken to evaluate the data protection software features enabled within the storage system. Storage consolidation within a SAN enables the consistent application of data protection and disaster recovery, assuming the basic Read More
Compaq's 8-CPU Intel Servers: the New
Compaq started shipping its eight-CPU Intel servers, the ProLiant 8000 and 8500, in late August. These are the first true eight-way Intel servers to ship.

disk raid  house up to 21 disk drives, allowing lots of raw storage space, but also providing the flexibility for a large RAID setup. Price/Performance: Based on present $/tpmC results from the TPC, Compaq continues to be a price/performance leader ($18.70/tpmC). We expect this leadership to continue, with the only serious competition expected to be from Dell. The raw performance numbers are also very good (>40,000 tpmC), but we expect Dell to post similar numbers within three months (60% probability). 8500: Read More
Peace of Mind through Surveillance: Affordable Solutions for Homes and SMBs

As additional cameras are added or cameras with greater resolution are deployed, administrators can expand the hard drive capacity without interrupting Surveillance Station service. Recording events as a method of security only provides peace of mind if the events can be viewed at a later date, and RAID configurations ensure recorded data remains relevant and useful. Remote Recording If Read More
How to Find the Right Virtualization Solution for You
Is scrambling to consolidate and virtualize your information systems department frazzling you and your hardware? Are management and infrastructure costs not as

disk raid  of a single failed disk drive. RAID 6 extends the data protection of RAID 5 by writing a second set of parity data. RAID 6 provides high storage utilization, because it requires only a single drive beyond RAID 5 (N+2). RAID 6 provides enhanced data protection and the cost savings of requiring only one additional drive, but there is a tradeoff in performance. RAID 6 requires double the number of parity calculations and additional writes associated with RAID 5. Because of the negative performance impact of Read More
Compaq and IBM Alliance for Storage
Compaq and IBM will now cross-sell each other’s storage products, and will work together to make their storage hardware and software interoperable.

Each company plans to provide equipment, software, and staffing to support each other's open storage networking/SAN customer centers. At these centers, customers can see for themselves the interoperability of both companies' technologies and products where real-world testing demonstrates the value of open storage networking solutions. Market Impact As with most agreements of this nature, Read More

Delivering Information Faster: In-Memory Technology Reboots the Big Data Analytics World
In-memory technology—in which entire datasets are pre-loaded into a computer’s random access memory, alleviating the need for shuttling data between memory and

However, with the onset of big data, as well as an insatiable thirst for analytics, the industry is taking a second look at this promising approach to speeding up data processing.

Dell Drops WebPC
Dell Computer Corporation has decided to drop its 'WebPC' appliances, with somewhat less fanfare than was created for its November, 1999, announcement.

(Prices vary depending on how much processor, RAM, etc.) Dell's leaving will have two contradictory effects on the Internet appliance market. The effect on consumers is, paradoxically, no effect - there are enough suppliers out there now that customers will be able to find an appliance if they really need/want one. Although Dell is certainly a popular brand, it's not clear that brand loyalty carries over to the relatively new appliance Read More

This product is aimed at the large datacenter/data warehouse environments, as well as other large-scale computing environments. The 8450 will also be used to consolidate and upgrade existing servers. Dell's main competitors in this space are Compaq, HP, and IBM. There are other vendors producing eight-way Intel servers (e.g. Unisys, Hitachi), but we do not believe they will be serious market share competitors. (Market share figures Read More
