Quick LSI RAID Question

@momurda said in Quick LSI RAID Question:
You could make a big array, then when youre installing windows make a 350GB partition for the windows install, then use the rest as another disk(data i guess) for that server.
Doesnt work. Windows sees the single RAID volume as 1 "disk" and since that disk has over 2TB partition, it has to be GPT. Per SWJ, I cant create 2 volumes on the same raid array
Thanks for the help though

Even though the RAID controller won't provide the partitions for you, does that matter? Assuming that the OS will see the entire 5 TB partition, Windows should allow you to create a 350 GB boot partition that you install Windows to, then format the rest as GPT and call it a night.
It wont work. Windows cant boot to a GPT disk if there is no UEFI motherboard installed. Im going to just add a couple more disks and setup disks as the boot volume. Then use GPT on the existing 5TB volume.
My next problem is to figure out how to get this card to allow me to connect 6 drives in the cheapest, most efficient way possible while not sacrificing performance. I have a SF8087->4 SATA connector breakout cable right now. Sounds simple, huh?
You need a port multiplier to connect more than 4 drives with that card. (Marvell 9715 chipset is the one I know is used by Backblaze. Not exactly the greatest storage setup, but it'll work.)
Thanks Travis! I looked around and couldnt really find one with that chipset. Do you have any other recommendations? Also what is the performance impact of using the port multiplier card?
I see good reviews for a company "IO Crest" on Amazon. Anyone heard of them before? I can order through Insight if anyone has a good recommended card that isnt available on consumer sites.

They don't actually say on the blog page. I haven't actually used any myself, but you do have one options that I found.
Amazon 1 to 5 port.Next time I'd just get a card that has enough ports on it already, or a server case that included the needed backplane.
Performance wise, you will only get a max of 6Gb/s per port, no matter how many drives are connected to the port.

Thanks. Unfortunately this is an upgrade instead of new build, so buying a $4-500 replacement card wasnt needed untill I ran into these GPT problems.
I am open to purchasing a new case w/ backplane if anyone has any good suggestions.

Is this a custom server? Never saw a model number mentioned.
-
A newer motherboard with uefi would be cheaper than a newer rackmount case with backplane. cases like that worth buying cost $500.

yea its custom build using an Antec 900 Case

no rackmount

Yeah, seriously, replace the motherboard!

Aww, I didn't realize that you could only have a disk be either GPT or MBR... maybe if I was less tired.. yeah I'll blame it on the jetlag.

You dont use server racks or virtualization?
You also missing the point about whether or not you have a rackmount case. Buy a new motherboard, still a better option that whatever you are thinking of doing. By the time you have found a solution to this, you could have a new board from newegg or amazon in your hands. hell, you could go to local mom n pop store and buy one in less than time than it takes to reply to this.
OR
make that big raid volume like you want, then put another disk or 2 in the leftover mobo ports(since yorue using a raid card for the big volume), and install windows on that disk. The data is what is important, not windows install. That can be replaced in minutes. -
A new used server might be a better option at this point, assuming you can find one that fits your needs.

@momurda said in Quick LSI RAID Question:

They use whitebox desktops as servers, no virtualization. Nothing enterprise is allowed. We've been discussing this in other threads and offline as well. It's nothing to do with price, in fact it is costing a ton. It's one person's personal agenda and nothing to do with needs, resources or anything. But yeah, none of that stuff allowed.

Yeah, mobos are decently cheap, especially as these are nice desktop ones. Updating that to UEFI is easily the simplest solution. Replacing the LSI instead of the mobo is going to cost way more.

RUN - RUN away from that company as fast as a new job will allow - or even faster if you can afford to be without that job for a while!
