CPUs, Cores and Threads: How Many Processors Do I Have?

Even SSD's work on the SATA subsystem - SSD efficient, but what of the SATA limit? Drives will need to be 'on the board' with more efficient connections (Direct SSD?) Chip storage is going that direction I believe.
Not fast ones. PCIe cards have been standard for most of the decade. Look at FusionIO cards, as an example. That's what servers normally use. And faster 1.8" hot swap SSDs come with an M.2 interface. SATA and SAS are only used for entry level SSDs.
-
High speed SSDs today are just one step removed from being system memory.
-
PCIe is good, but in most cases I have seen it is primarily for graphics, so it is designed for large data transfers to the bus, and transactions back seem to be for result based calc's. I would like to know more about PCIe, and its connection to the source, time to visit a Maker's site.

I've never seen it used for graphics. Not that it isn't, but I've never seen that come up.
PCIe SSD cards are the standard for high end servers. Million plus IOPS per card. Very low latency, huge bandwidth.

Sorry, I was thinking of your Compaq Deskpro. Compaq, do not age yourself that way. (HP thrown in for good measure).

Article was from 2008, they were still Compaqs then.

@scottalanmiller Sure, I 'believe' you. Yes old with no good formal bus training. I am impressed to see your article, and the depth of your input. Thank You.

If you check the Google cache, or the Internet Archive Way Back Machine, I'm pretty sure that it shows it from early 2008. That was one of my first articles written while working at the bank. Back before SMBITJournal was around.

@scottalanmiller No, I am sorry, the first part was in jest, the rest true. PC (Compaq) is old with no good formal bus training, should have clarified this. I 'believe' you wish not to age yourself as I do. I have removed Compaq from my vocabulary. Sorry thing, once I was certified for their products. Hmmm.
-
I was always a Compaq fan. I came to Compaq by way of being a DEC fan in the 1980s (@Minion-Queen is an ex-DECer BTW!!) and then to HP by way of Compaq. It's the Proliants and DeskPros that won me over, not the NetServers!
-
I still own a 200 hz proliant, in my garage somewhere, whole 6gb drive and all. Backplane made upgrade's a Compaq only design. Great proprietary machine that will never be more than it is.
-
OOP's Proliant should be Presario, home machine. My Wife bought it for me as a gift. Proliants were at work, and workhorses they were. NT4 Days, replacing Novell servers left and right.

Ah, Presario. Yes, those were garbage. Compaq did not make those, they just rebranded them.
-
Yes, in the garage, in 20 years maybe as the apple 2+ worth 5$, she spent 2700 for it, and I feel it is not depreciated yet, decomposed yes, but wow I cant throw out 2700. I know garbage when I see it, I wish she would have asked me first, that is when I started to bring work pc's home.
-
I still have FOUR Commodores! Not including my Amiga.
-
Atari, anyone?
-
Ohio Scientific, Trash 80?

This thread is making me nostalgic for nicotine yellow plastic and the smell of old electronics getting warm

That was a great, very detailed, explanation of the what, but I'm actually rather interested in the method of determining how many are needed for specific tasks. Another article, possibly?
