You may have noticed that all Compucon desktop models have 1GB (2x 512MB) as a base point as from the last pricing update. Jasper and Diamond have 2 memory slots only as they are for process workers with less demanding computing requirements. The good news is that Jasper has recently got an upgrade to 4GB max capability (2 DIMM slots each capable of taking 2GB module). Of course, we seldom want more than 2GB due to 32bit OS addressing limitation. Both Jasper and Diamond support dual channel. Dual Channel is a bigger pipe but achieves something like 3% to 5% memory throughput improvement only due to high memory transfer latency.

The CAST seminar held on 23 April was attended by 17 channel members including 5 first-timers. The event is certainly a big effort on the part of Compucon, but how did the effort benefit channel members?
We have talked to a few channel members who keep coming back to the seminars and analysed the feedback from all first timers for some clues. The two camps do not have the same view.
Repeaters advised that they see more value in the seminars the more they repeat the attendance. The seminars help build and reinforce their knowledge, competence and confidence gradually. First-timers have different opinions. Half of them found the content boring or “can do without”. The other half is cautiously favourable about the seminar.
We could say knowledge appreciation is a gradual slope, the more you know the more you learn and appreciate. Some may say this interpretation is biased as we try to justify the efforts. Feel free to give us different views.

Many of you have met Cheng Chuan from Tandberg Data in a previous CPD session. Cheng Chuan is flying in again on 13 May 2008 to give the Compucon channel a special boost. He has offered to do an overview of backup scheme for us. Cheng Chuan has worked in the storage division of IBM and Computer Associates before joining Tandberg, and is well qualified to address issues and methodologies of server data backup. We have heard of jargons like de-duplication, recovery point objective (RPO) and recovery time objective (RTO). We will find out exactly what they are. Also, being a world class server data backup equipment vendor, Tandberg would have the solutions ready for us. Remember this: Tandberg has not offered the same to other parties in New Zealand- it is a unique opportunity for the Compucon channel members only. Please make use of this advantage to boost our business capabilities and reply to this newsletter to register. The outline of the seminar is as shown below. Time is from 4:00pm to 5:30pm, followed by wine and cheese until 7:00pm.
- Backup General: Differences between redundancy (RAID, Clustering, Replication) and data backup; RTO and RPO
- Backup Technology: DAT, DLT, SDLT, AIT, LTO; HDD Based; Optical Disk based
- Backup Software: File Based, Image Based, Continuous Data Protection
- Backup Strategy: Local, LAN and SAN Backup; Disk to Disk to Tape
- Tape Rotation: Tape Rotation, Off Site, Encryption

Our standard system production procedure includes a full Build & Verify on all Hardware RAID configurations and we also simulate hard drive failure to test its fault-tolerance capabilities to ensure the arrays will function properly as designed. The simulation testing is included by default as part of our production service as from 25 March 2008 but it is optional as it extends our delivery time to you by 24 hours. Please let us know if you want to waive our default simulation process. The above information is also given on the Pricing Guide sheet of our MPG system

Asustek will add AUTO as the default BIOS setting for Cool and Quiet soon on AMD based motherboards replacing DISABLE which is the current default.
CnQ does 2 things on Athlon64 CPU: adjust the frequency of the CPU according to workload and speed of the Heat Sink Fan according to temperature of the CPU. CnQ reduces the processor’s clock frequency and voltage when the processor is idle. This lowers power consumption and heat generation and thus allows for slower cooling fan operation (hence quiet). Customers can choose to enable CnQ via Win XP Power Options from the Control Panel. See PDF attached or in the knowledge base of www.compucon.co.nz
