SPECjvm2008 is a benchmark suite, containing several real life applications and some benchmarks focusing on core java functionality. The main purpose of SPECjvm2008 is to measure the performance of a Java Runtime Environment (JRE). It also measures the performance of the operating system and hardware in the context of executing the JRE. It focuses on the performance of the JRE executing a single application; it reflects the performance of the hardware processor and memory subsystem, but has low dependence on file I/O and includes no network I/O cross machines. The SPECjvm2008 workload mimics a variety of common general purpose application computations. These characteristics reflect the intent that this benchmark will be applicable to measuring basic Java performance on a wide variety of both client and server systems running Java. SPEC also finds user experience of Java important and the suite therefore includes startup benchmarks and has a required run category called base, which has to be run without any tuning of the JVM to improve the out of the box performance.

Fiber Channel speed, Brocade races ahead of Cisco by doubling the speed
To whom needs a background:
A year ago, speeds are 2,4,8 Gbps, 2Gbps is almost obsolete, and the most used and purchased in the local market has been the 4 Gbps, the 8Gbps has been an expensive luxury that we don't need.
Brocade is a network solution company, which is not well known in the local market, its presence is almost zero in the Libyan market, Now Brocade beats Cisco with it's 16 Gbps FC, double the speed.
This will not affect Cisco presence in Libya in the mean time, by the time we start needing the 16Gbps, Cisco would have its products with that level. unless Brocade fights to have a presence.
In datacenters, data files and databases are stored in "Storage" ,in other words, a box of disks, with different technologies and topologies which are available in the market. Like SAN and NAS storages, these storages can link to your computer (server) through a SCSI , SATA or fiber connection.
The speed of the ports on the storage box , and FC (Fiberchannel) on the server, will affect how fast your data moves from the storage box to the server and vice versa. This also affect other things like connectivity with remote sites, backups, and so on.

custom-made Server Solutions, Is it a need in the Libyan Market?
I've been browsing here and there and ran into the ZT company, it's an american company that provides custom made servers, Like the way we collect parts into a working desktop.
Most of the times I've been to a customer datacenter, the server is not fully utilized, especially the virtualization concept has just began to have an existence in our datacenters, I can't blame the engineer or presale who chose the model and specifications, because I've been in their shoes before, when building a BOM (Bill of Material) I find myself stuck between two models, RAM levels, or different number of PCI slots...etc. First choice is below minimum requirement, and the second is away above required.
SO, I tend to the custom server idea, BUT the Libyan market is not ready for such an idea, we look for the brands we're familiar with, and the rule of purchasing is "I won't be the first one to try it"
