Summary of last two days
Chris and Jin leaved Powerleader in 15th,September.They are both very good men from which I’ve learn many things,especially carefulness and responsiblilty. I think I would work with them for more years,but it isn’t in the same way.
Summary of last two days:
——————————————-
1.Mr Ji, from Xiamen City,said PR2510 could use many cpu resource on the Red Hat Advanced Server 3.0 with Update 4 even there was no process running. He also told me the avg cpu time is very high when he tried to copy some big file to local harddisk. I’ve read his report which seems have heavy load created by issued iostat command.
In the Saturday morning I installed the RHAS3.0 u4 in a SE7520BD2 platform,and then issued the top and ” # iostat -k 1 9 ” command, the result I got was normal.it showed the cpu works very well in our products.
I’ve written to Mr Ji and called the Sales name Xu Huauying.
Level: Crit
2.Xie Wenyu, Sales of Chengdu,who wanted to know whether the 8931GT ethernet device could take the place of 8931MT which had been stopped producting in PR6310 (SE7320SP2).I’ve told Du Xuewen how to test this device,and he did well as a frashman. Xie said the customer want to install WinXP in PR6310,but as the result,it would be blue screen during installing WinXP.Finnally,we used Windows 2000 server.
Level: Info
3.Zhang Zhihao,customer from Shanghai,asked some question about RAID.I told him SE7520 could not rebuild RAID data automatically,for example, in RAID 1 mode,if one harddisk was halted during the system running, it did not effect.But after reboot ,it would check the harddisk’s status and said one harddisk halted and the RAID was offline. We had to changed another harddisk whose capability must be bigger than the original,if it is smalled,the Rebuild function is unavailability.and then Enter the RAID configuration interface to rebuile the RAID in order to keep our data safe.
I’ve promised to send some documents about RAID to him in few days.

3.Reflashing logo of 7501CW2,Nanjing Fenghuo.
The picture format must be 640x480x4bpp and smaller than 320KB.In the pure Dos environment,issue the following command: a: 3.bat Xeon480.bmp
Level: Closed
4.Liu Quan,sales of Shanghai.SE7520BD2 only supports RAID0 and RAID1.If we want to create RAID10,the following RAID card would be choosed:
Adaptec 2200s, Intel SRCU42L,SRCU42E,SRCU42X ,
Mega Raid LSI 320-0,320-1,320-2.
5.Yang,inside sales of Shenzhen.The capability of NvRam in the SE7520BD2 is 8MB.This mainboard does not support Chipkill memory technology.SE7501 chipset supports 533MHz/400MHz FSB and SE7520 chipset supports 800Mhz FSB.
PC2100 = DDR266, PC 2700 = DDR333
LVD = interface of SCSI
Next:
——————————————
1.SATA – SATA2 conversion TEST (about TWO weeks).
Shu Ling will tell us which type harddish would be used and tested.
PT6250,PR2310,and then add 3ware RAID card in one of former two products,so we are going to prepare for three tests.

2.JR2-DDR2 platform TEST.(release at 11th,Oct)
Using intel 2400 platform.
