so… yea… newest probs— the whole LHe and the SATAe thing- it is an 8bay sata raid configuration out of the Highpoint card with the “harmonica” being the intermediary. I said we were losing the drive- which may have been the drives… but as of recent we plugged a new sata array and lost the computer— so something here is not kosher. I’m still eliminating user error, but as of yet I, personally, wouldn’t venture on the the whole “e” path. a couple more weeks/ a month… ish.

kona seems fine- just remember the diff with 8lane and 4lane and which one your product is actually made for.

its funny you post that question here, because i’m looking at an advertisement for the kona2 directly next to where i’m typing — “10-bit upconvert/downconvert…etc…”

got a fleet— they are still under testing at my facility and their sata raid brethren— I have not experienced any problems with lhe yet and have begun selling/renting them.

as for the high point’s pci-e… that’s another story, it continually drops our sata raid- that company bumped it’s head.

unfortunately frame dropping is like a cough, it is such a general symptom that it can be very hard to locate the issue- you could have: corrupt render file, corrupt sequence, corrupt prefs, too many sequences open, you could even have a drive failing— etc…

try to isolate the issue- is it the same spot on the timeline or are you dropping frames randomly… such questions are good places to start- and why aren’t you fully upgraded like the other comps on the san? 10.3.9 is a terrible os— very buggy.

and I have heard that xraid update is supposed to help for some issues… make sure everything is updated fully and completely. lastly, trash prefs, restart-

[Jordan Woods]

bottom line here, and as I’ve heard from most techs… apple screwed the pooch with the 2.5(replace it)- it is consistently the worst performing computer out of my fleet. i don’t know exactly why

to clarify, the message that was sent to me was this link, “https://www.xlr8yourmac.com/index.html#S20146”

-what i’m expecting here was a problem that originated somewhere between the chair and the computer, because I haven’t seen this conflict and it doesn’t seem like any of you guys have either… no worries-

[Jordan Woods]

try http://www.la411.com they have everything and everyone worth and worth not working with.

sounds like a corrupt render file… or a corrupt project, maybe corrupt media. if so, delete render files, trash prefs, redo a new project and paste in timeline— or export xml/edl which ever and relink media or rebatch if needed… either way, try to side step whatever you may think is causing the corruption.

I am still hacking away at that experimental raiding— was able to software raid multiple 8bay sata configurations, but the raid5 has not stood up to the test, it fails on writing— only prebuilt drive systems like xserve raid has been capable(hardware raided though)

and yes, the HBA thingy is a major pain… how many cables do you like streaming out of the back of the computer?

-but our custom 8bay raid(0) systems rock out on uncompressed HD without problems, clocking 340mb/s sustained speeds

i’d love to know if Highpoint gets it together and their raid5 actually works with this new pciE deal…

If you go with what you said “1 big SATA->4Gb FC RAID enclosure with a built in 4-port switch plus 2 4Gb FC cards/cables,” you would be fine… be warned though that almost every raid configuration is atleast volume level locking, so you definitely won’t be able to write at the same time(not a prob you said)— an Xsan solution would allow concurrent writing just not on the same file (file level locking), but what a pain in the @ss. If you bought a Facilis system up to 24bays at 500gb= 12TB storage and as little as 8bay=4TB system— you could cut it up and share it with the two computers and possibly not need a SanBox(Qlogic or otherwise)— you could be writing to the volume of one comp and reading from the other- these are all 4GB fibre solutions— there are others but i’m most familiar with xsan, facilis, and fibre Jet— it’s almost too much to fit here, but you seem on the right track. My friend usually handles this for me, nathan@thedrgroup.com —i’m sure he could answer your questions fully.
