Install vmware on Mandriva

2008年2月20日 没有评论

Install the kernel source package:
#wget ftp://ftp.univie.ac.at/systems/linux/Mandrake/2007.0/i586/media/main/release/kernel-source-2.6.17.5mdv-1-1mdv2007.0.i586.rpm

In “vmware-distrib” directory, and invoke:
# perl vmware-install.pl
Note, do not invoke vmware-config.pl at above progress.

Download “vmware-any-any-update109”:
#cd vmware-any-any-update109
#perl runme.pl
This perl script will execute vmware-config.pl automatically.

This method has been proven in my mandriva2K7.

Hardware Unique Identifier and LFS building

2008年2月20日 没有评论

How to unique identify a computer? Google said CPUID and MAC address are two most widely used. However, CPUID is lease to modify than MAC. Later I find “hostid” command, which print the numeric identifer for the current host. However the hostid is related to the IP address of local computer so that it can not be depended.

CPUinfo’s BogoMIPS: The Linux measures BogoMIPS at start up in order to calibrate some soft timing loops that will be used late on. Or, it is measured provided in the Linux OS that indicates in a relative way how fast the computer processor runs.

Configure script problems: If something goes wrong while running the configure script, review the config.log file. This file may contain errors encounted during configure which were not printed to the screen.

Because there is not always enough Random Access Memory(RAM) available for compilation processes. It is a good idea to use a small disk partition as swap space. This is used by the kernel to store seldom-used data and leave more memory available for active processes.

To check if your host system used custom enhancements:
#debugs -R feature /dev/xxx

Toolslain: compiler, assemble, linker, libraries and few useful utility

Pilot production & LFS

2008年2月19日 没有评论

We are going to try out production about BX1200 in few days. Inventec has confirmed that 18 pieces of SS2280 and attached 19 pieces of SJ2280(JBOD Devices) will arrive at Shenzhen at Feb 22nd. I discussed with Shan, Xiaoyu, and both of us agree to arrange the pilot production in Shenzhen Lab. Also we need 20 pieces 44pin Flash card, Shan will be responsed of buying these disks. Test team and Shan will do the job while they still need technology support by RD team.

Gavin assigned system-building to me, which is charged by Huang Pengcheng before. It is a good excise for self-enhancement. I will study LFS and do some testing in the following two weeks.

BX1200 knowledge protection: According to unique MAC information of network cards on board, it is able to create a key or called license to band with Flash card. The customer can not steal our achievement when they copy the content of flash card and try to apply it in other SS2280 platfrom, which they could buy from Inventec.

Though my suggestions perhaps are not always accepted or recognized as reasonable, it can not cut off my thinking. Keep good habit and do better to improve myself.

BX1200 with JBOD ready

2008年2月18日 没有评论

We have received two BX1200 platforms and JBOD(SJ2280) from Inventec, which is used for our v1.1 development. About the sample SS2280 issue, I wrote to York and got promise from him: Inventec agree us to send the whole system to their Shanghai team for farther investigation and fixing.

2008 Preview

2008年2月17日 没有评论

I came back from Hunan at Feb 15th, where I went to take part in Yang Ming’s wedding. It’s very cold in Hunan, even somewhere there’s heavy snow existed. During seven days staying in Hunan, I made a mistake, which is now seemed to be caused by a small misunderstanding matter. In fact, I love my wife, and I know she loves me deeply too. I can not hurt her heart any more. Yes, I must try to control my bad temperament, and be calm. It would be a difficult thing, while difficult thing always means right.

First off, I should insist writing blog here, recording all the things considered meaningful and useful in general working. This blog has been maintained from three years since June of 2005. It is proved to be benefit for my IT career. Good habit would be kept all the time.

When I asked Gavin for some suggestions, he told me to improve myself to be widely developing. I know my situation in current team and what he expects. Sometimes I am not confident enough for lacking full developing and good-communication skill. These two should be highly concerned. The prior one, I decide to read more books and make my work at higher rate. The second one, I have brought a relevant book about speech skill from Shenzhen library, and plan to read it in one month.

Oral English, perhaps is the next important middle stone in career. Obviously oral ability is more and more important in IT field, in which we have to communicate by English.

I am captivated of Japanese culture, especially history and novel. We can learn a lot from this neighbor. Now I am reading Ryunosuke Akutagawa, whose famous representative working are Rashōmon(1915), Hana The Nose(1916).

Windows XP Service Package 2

2008年2月16日 没有评论

I have only a Windows installation CD at home, and later I find it does not contain service package. This Windows is setting up as Chinese, so I download a copy of sp2 from Internet. When try to install this new package, it has error and displays the language is not meet. I google from some hints, a fellow said this issue may be fixed by changed the local language parameters in Windows register table. Some illegal Windows copy are based on Singapore Chinese, not main China. As follow the steps and reboot, I can not log on Windows because it warns me that the license has been recognized as unavailable. I has to boot system to safe-mode, and restore the former setting to make the system be normal again. My aim is burn other ISO located at my T23 notepad and install Windows again. Later, I reinstall the system with new Windows CD which is English version.

BX1200 Special Version Ready

2008年1月29日 没有评论

BX1200 Special Version, which is dedicated for PowerOn Tech. is ready today. I have noticed Shan Xiaoyu he could download the firmware now. As expected, a piece of BX1200 will be sent to PowerOn tomorrow morning. There will also a related training about this product in the next day.

I’ve received two Tyan platforms(Code:5372) from Zhang Rongqi, and these two machines are used for our next NAS Gateway products, which will integrate IPMI to instead of early APC fence devices. However, we have to research and study more about IPMI applications.

Server Board and chassis for next generation of NAS

2008年1月16日 没有评论

There are two boards seemed suitable for next generate NAS product. In fact, both of these products should be installed in SuperMicro 5120F-280 or 5130F-430 chassis. Their processors must support 64bit operation system as my yesterday description, and the DDR2 memory is considered better than FBD memory in our application. And the last one, maybe the most important point, is when externel IPMI card is inserted in its identified slot, the IPMI management interface is quite different between the above two board. One shares with on-board ethernet ports, and the other has dedicated RJ45 port. Gavin suggested the first one is better because it will make system architecture more simply.

The disk driver adapter functions of the Super I/O chip includes a floopy disk, driver controller that is compatible with industry standard 820777763 data separator write pre-compensation circuity decode logic data rate selection, a driver interface contrl logic and interrrupt and DMA logic. The Super I/O supports one PC-Compatible printer port(SSP), Bi-Directional Print Port(BPP), Enhanced Paralled Port(EPP), provides functions that comply with ACPI, which includes support of legacy and ACPI management.

SSP, STP protocol

2008年1月15日 没有评论

When I check the information about disks via BX1200 Web GUI, I find that all SATA disks’ vendor is marked as “ATA”, while SAS disks’ vendor is “Seagate”(We use Seagate disks on that BX1200 platform). It is considered to be accepted in current version.

SSP: Serial SCSI Protocol
STP: Serial ATA Tunnel Protocol

Some famous storage vendors and its NAS products:
EMC: Celerra NS series
IBM: NAS Gateway 500
Sun: Storage Tek 5320
Bakbone: Netvault(it is also used in Plasmon’s SNAZ) for backup and recovery.
ADIC: Tape devices, an American company
FalconStor: Tape devices, and corporate with EMC

MWC: Mirror Write Consistency, when transfer data to remote host, and at the same time it also need to be written to local disk. This locate writing operation only be done after get the confirmation from remote host.
