https://community.hpe.com/t5/disk-enclosures/smart-array-6404-256/m-p/3988858#M23617 I purchased a Smart Array 6404/256 and installed it into my rp3440-4 (HP-UX 11.23) server. The Smart Array is connected to my MSA30 D-B which has six 72GB hard drives on each channel. <BR /><BR />My question is with the stats that I am getting on the card. When I run sautil /dev/ciss4 the Array accelerator (cache) information gives me the following information.<BR /><BR /> Array Accelerator Board Present?.... yes<BR /> Cache Configuration Status.......... cache enabled<BR /> Cache Ratio......................... 50% Read / 50% Write<BR /> Total Cache Size (MB)............... 128<BR /> Read Cache........................ 064<BR /> Write Cache....................... 064<BR /> Transfer Buffer................... 000<BR /> Battery Pack Count.................. 2<BR /> Battery Status (pack #1)............ ok<BR /> Battery Status (pack #2)............ ok<BR /><BR /><BR />If I am reading this correctly the Total Cache Size is only 128MB with Read cache being 64MB and write cache 64MB. I downed my server and pulled the 6404 card and the memory says that it is 256MB. <BR /><BR />What am I missing? How can it say that it has 256MB Cache but only 128MB Cache shows up? Would I get better performance if I increased the Cache? Wed, 25 Apr 2007 14:40:27 GMT Jeffrey F.
