Hello!!

Thanks again for your posts, its very kind from you all the advices.

Now its time to get the ATTO, install it and make some tests. anyway if the infortrend wont work, ATTO wont be a waste of money.

It will take time to take it, however I will post my tests here to let you know or to ask for help to a proper ATTO config.

All the best,

Alex

Have a good weekend!!

I will come with more new test on Monday… and Walter, I know its an advice, and also I would like to take everything brand new and not to build a something with spare parts and its a blame this stripe but it would be fun to see you in my position with the great budget I have.

But its ok, if this config wont work, at least I have the ATTO FC and the MacPro, both usable if I need to get a new array.

Cheers!!

Hi Gary,

I have NEVER EVER seen a 200 MBps on a single bootable drive in my life. The theoretical MAX speed limit on a single SATA drive is a little over 100MBps, That is a server class drive that would not work in your mac. Either you are guessing or your math is incorrect.

Forgot to mention the boot drive is stripe… I have to remake the SO, I dont like this kind of config…

LSI only ever created the Apple Branded FC cards- why are you trying to hack together an old LSI FC card in your Mac?

I apologize 🙂 I found it this way when I came working here 4 months ago, so dunno who/why bought it…

Not with a split array. not DPX. You will not get realtime playback at 23.98 for more than 15-30 sec until the cache throughput maxs out.

I get it, dont split, it has sense…

You are attempting to muddle thru a very complex and hardware intensive editing process without trying to get the proper support for a hardware config like this- you cannot slop your way thru one of the most complex hardware configurations needed for highend editing. There is a vast amount of info needed to accomplish this task – raid config, raid cache settings, block size, raid levels, hell even the config of the Atto card is important to maximize the bandwidth.

I never though it was going to be easy, and thats why I started to write in this forum 🙂 coz you all have more experience than me, more knowledge with raids, bandwidths, etc…

And I believe that its possible to get what I want with the minimum costs, this means buying only the ATTO and using what I have.

So do you think this config will work whatever the amount of info needed?

Thanks a lot,

Alex

Hi Walter,

The program is:

AJA XENA System Test Version 1

From AJA, with this program you can make bandwidth tests against your disks with different resolutions and different sizes of info.
Being from AJA I trust on what they say.

I just asked infortrend how much will I get using the ATTO 42ES with their box…

Hi Walter,

I just did a test with the AJA test program in a windows system, it has connected another Infortrend, 24 raid5 disks and the bandwith I get are 350MB/sec writing and 380MB/sec reading.

I hope this is enough, or not? 🙂

Hi again,

To Walter:

The first tests I was making were on the system disk (200MB/sec) and SAN drive (not full speed channel) also another 218 MB/sec, both reading writing as average.

So thats why I want to implement the infortrend box, with null result due LSI HBA…

To Bob:

Much cheaper?? I guess you mean disk arrays, yes they are more cheap than infortrend ones, but happens I already have one. The thing I want is to use the two channels and split the disks, some for the system actually working (just keeping info) and some for the thing I wanna.
If the system with VTR Xchange + MacPro + Infortrend + WhatEverHBA (I hope ATTO 42ES) are gonna give me the enough speed to get what I want I will buy the ATTO, the only thing left…

My decision to get ATTO is both are verified by SAN provider and Infortrend, also ATTO has been working with Mac during ages.

So… do you think with this mentioned config will I get the bandwidth to get even 2K??

Thanks again 🙂

Hi all,

Thanks a lot for your answers.

The main goal for me is to get HD, both ways 422 or 444 with Kona3, 2K files is a bonus.

I tried to connect infortrend A24F-G2430 (FC to SATA) to MacPro, but the LSI 7202EP doesnt like it at all… Or anyone has one connected?? I just checked compatibilities and they dont match…

So now the option for HBA is ATTO FC-42ES, 4Gb FC.

So with A24F-G2430 and ATTO FC-42ES, do you think I would get those 300 MB/sec or even more??
Which kind of raid? raid5? how many disk in that array?? I can get up to 24 disk.

Thanks in advance and have a great weekend 🙂

Hi Gary,

Where is it “capturing frames” option?? I just checked and I cant find it. I just followed the manual to get HD and 2K when setting up video input, etc… saying I want files (dpx) and not only quicktime.

I agree about 300 MB/sec, but if I can do it in FC in the same computer, why not with VTR Xchange?

I will attach a 2GB FC array disk and make the test to ensure more speed in any case…

Thanks a lot,

Alex
