Adaptec “Q” cards have been around in a few variants for quite a few years now, and we have quite a few devotee customers who think this technology is the ducks guts. So I think it’s time to introduce our two newest, and only required, “Q” twins … this of course doesn’t change our official card names in any way shape or form – it’s just my personal way of naming things for easy reference…
Qi and Qie
No, they are not my Chinese cousins, they are in fact the 81605ZQ and 8885Q cards respectively.
Qi = 81605ZQ
Qie = 8885Q
So why the names? Basically because I’m Australian and we tend to give nicknames to everything. In fact I’m so bad at this that I have a habit of forgetting people’s real names and only remembering their nicknames. This can get embarrassing because some of the nicknames I give people and things should never be repeated to those individuals
Anyway, back to the subject. In reality I believe the only two “Q” cards you need to consider are these two 8 series products. Pricing wise they are the right cards to buy. Performance wise they are the right cards to buy. Feature wise they are the right cards to buy. In fact, imho they are the only “Q” cards you need to consider. So let’s look at my logic …
Qi (the “i” stands for “internal” and therefore of course the “e” stands for “external”). If you are looking to improve the performance of your storage system on drives internal to the server, then this card fulfills all your requirements. If you have an 8-bay server then fill it up with big hard drives. You can fit SSDs just about anywhere in your server … there are even adapters that let you put ssds into the place of slimline CDROMs (which are not required any more in servers as you can install your OS from USB stick). So basically you can treat the card a 10-drive adapter (8 x hdd in hot swap and 1 or 2 SSD anywhere in the server).
Of course, if you have a 16-bay server then this card can also cope with that many drives directly. So who cares if it has more ports than you need – the price/performance/function is right.
If you are going outside the server to JBODs then the Qie is the right card as it lets you do such crazy things as fill your head unit up with SSD, and attach lots and lots of HDD in the JBODs … the drive combinations for your caching or tiering requirements are pretty much endless with this card.
So meet the twin … Qi and Qie … they are worth getting to know. In reality I’m sick of trying to roll 81605ZQ/8885Q quickly off the tongue … Qi/Qie is much easier to say
As an aside, Australian’s have a weird sense of humour (and spell using the Queen’s English, which this spell-checker is having problems with). We tend to speak to one another in derogatory terms and use nicknames/slang to the point where most people don’t understand a word we are saying. So, to the American lad (won’t use the Australian slang for Americans here as it can be construed in way too many ways), I’ll have this to say:
“Australia and America are two countries separated by a common language!”
