Review: May 5th – June 18th
HDD lost issue was found at May 5th, as Liu Changjing verified the units sent to customer. Later, we tried almost all LSI firmware including original 6.0.1, 8.0.1-0035/38, and even the latest 9.0. While all this versions have various problems: HDD lost during fast initializing and slow initializing, and 9.0 can not recognize attached JBOD device at all. After contact with manufactory, and decided to upgrade from current backplane firmware 2.92 to 2.94, tuning the i-Button parameter(Post Delay =2). Till not, neither of above can resolve this issue as it seems we did not find the root cause.
Shanghai, an important customer need high-performance equipment, including Quad-Core, and 16GB Fully Buffer DIMM, it will encountered unexpected shutdown when load very heavy. Now, we find it is caused by no sufficient power supply. A solution is change the fan boards cables to motherboard, which is now shared from the backplane and harddisk.
I’m very tired during these days, and I know I can not lose confidence by myself: Life is going on, I must fight with my fate.
