Super-low power CPUs¶
Atom C3000¶
Atom C3000 aka Denverton. Supermicro is making some, list, Gigabyte too. Nothing available as of 2017-10-02. I asked Interpro about prices and availablity for the following:
$280 A2SDi-4C-HLN4F 4-core , 8 SATA, 4x1Gb
$427 A2SDi-8C-HLN4F 8-core, 12 SATA, 4x1Gb
$603 A2SDi-12C-HLN4F 12-core, 12 SATA, 4x1Gb
$714 A2SDi-16C-HLN4F 16-core, 12 SATA, 4x1Gb
$? A2SDi-TP8F 12-core, 4 SATA, 4x10gb, 2x10Gb, 2xSFP+, SO-DIMM
$833 A2SDi-H-TP4F 16-core, 12 SATA, 2x10Gb, 2xSFP+
$479 A2SDi-H-TF 8-core, 12 SATA, 2x10Gb
Some of these boards have Intel Quick Assist Technology aka QAT, which is hardware crypto stuff. The drivers are FOSS, but the devices require loading non-free binary blobs (which are in firmware-misc-nonfree). Scary stuff. I don’t know if there is a way to use the system that ensures QAT isn’t loaded, we need to investigate more.
Atom C2000¶
Atom C2000, 8-core, 4 SODIMM slots (25GB/s memory bandwidth!), uses similar architecture to haswell, uses Xeon cores, 20W, includes 4x 1gb/2.5gb NICs, cheap, awesome. Basically the main downside compared to haswell is lack of additional channels to talk to pci-e slots, but it makes up for that by having most of the stuff we want onboard (sata, usb3, nics). So for systems where we won’t be adding additional SATA controllers or NICs, it is a cheaper alternative. Also some vendors are including interesting things on their boards like extra sata controllers.
Two versions: Avoton and Rangeley. Rangeley is the same as Avoton plus,
Rangeley is a tweak of Avoton that turns on the QuickAssist Technology (QAT)
accelerator on the chip, which hooks into Intel's Data Plane Development Kit
for network gear makers to juice AES, DES/3DES, Kasumi, RC4, and Snow3G
ciphers, MD5, SHA1, SHA2, and AES-XCBC authentication, and Diffie-Hellman,
RSA, DSA, and ECC public key encryption. This QAT coprocessor can process
ciphers at 10Gb/sec. And by the way, not all of the Rangeley chips will have
this QAT accelerator activated; to be precise, only four out of the eight
SKUs will. The reason for this is that the QAT accelerator is a controlled
substance and the US government has export controls on it.
We should be suspicious of built-in crypto, it’s unclear if any of it could be used safely.
Atom C2000 boards¶
Supermicro
Two boards, both are octa-core, 4xSODIMM, 6xSATA, 4xNIC, 1xIPMI NIC
A1SAi-2750F (Avoton) $359.65 @ interpromicro.com, Review
A1SRi-2758F (Rangeley) $359.65 @ interpromicro.com
This combo is mainboard+cpu+heatsink. Compared to our haswell config this is $360 vs. $498.25 ($167.50+$311.50+$19.25). The ECC SODIMMs are more expensive ($95 vs $71.50 for an 8gb) so some of that savings is lost.
ASRock
Two boards coming in Nov/Dec, forum post. Both have 4xDIMM (full, not SODIMM), 2xNIC, IPMI, 12xSATA!!!
- C2750D4I Avoton X2750 Octa-core review – $373 (newegg)

Celeron J1900¶
The Celeron J1900, a Bay Trail-D model, is also part of the Silvermont CPU family (like the Avoton above). It has similar specs to the Avoton, slightly lower clock, lower power (10W vs 14W), integrated graphics, and only supports 8gb of RAM. But it is MUCH cheaper since it’s high-volume, low-end desktop market. They are quad-core, 2M cache, 64bit and support hardware virtualization. Board+CPU combos are ~$55-80. They won’t have server features like IPMI and high end PCIe, but some have serial ports (or serial headers). They may not have the ability to do serial BIOS, but there is some support for Bay Trail in coreboot, it may be possible with some work to get coreboot working to get it.
NOTE: we haven’t tested any of these yet, but they are cheap enough we might try. If you try it, let us know.

Celeron J1900 configs¶
- DDR3-1333 2×4gb are around $75-80, for both SO-DIMM and DIMM.
- some of the boards support mSATA
- some support 2xSATA, some 4xSATA, so maybe 2xSSD and 2xHDD → $260-400
- they are all intended to be in desktop cases, but should all be low profile enough to fit in a 1U case if you remove the I/O shield and the case has ATX mounting holes and ATX power connector. Front panel LED/buttons might be tricky

(The X11SDV-8C+-TLN2F and X11SDV-16C+-TLN2F have a CPU fan for use in cases that don’t depend on case fans, but are otherwise identical to the non-plus models)
Older D-1450 listed in table below.
Previous Generation Intel Atom¶
The current shipping Atom CPUs are code named “Pineview” (platform is “Pinetrail”) and they are based on a 45nm process.
The next generation of Atom CPUs are code named “Cedarview” (platform is "Cedartrail) and are based on a 32nm process. They aren’t expected to ship until 2H2011. I have read two different rumors
- They will have twice the performance of the current
- They will only be about 5-10% faster, but their power usage will be way lower. One article said they are aiming to have netbook type devices where the entire thing only needs 10W!
If the latter is true (and I think it’s more likely) then it might not make sense to hold out for the newer ones. The pineview cpu’s are 13W, already nearly negligible for a colo server power budget. (maybe this will push us more towards the low power quad core cpus, since they are likely to drop in power with a process shrink and we’d get more performance)
The next version Atom will be: 2013, code name Silvermont, 22 nm
Previous generation atom boards¶
Atom D525 based
X7SPE-HF – $213.25 from Interpro
X7SPE-H – $181.55 from Interpro
Atom D510 based (older, but more available)
X7SPA-HF ~$180 (includes CPU)
X7SPA-H – doesn’t have the IPMI stuff and uses lower power Intel video instead of Matrox
hotplug options¶
while supermicro still doesn’t make any Atom based 1U chassis with hot-plug disks they do make this 1U chassis with 2 2.5" hot-plug slots and a 200W power supply
SC510T-200B ~$150
I emailed supermicro to ask if these were compatible (you have to check, because 1U servers can’t use a ATX style I/O port shield, it’s too tall for 1U) and they said they were. That mainboard has 2 ram slots and uses “non-ECC DDR2 667MHz(D510)/800MHz(D525) SO-DIMM”s, 2gb per slot, 4gb total.
fixed drives options¶
SYS-5015A-EHF – D525 based – $363.50 from Interpro
SYS-5015A-PHF – D510 based
These systems can only hold 1 3.5" drive or 2 2.5" drives, and they are not hot plug. The boards have 6 SATAII (aka SATA300, or 3.0Gb/s) ports.
AMD Based¶
(updated 2014/08/30)
AMD is launching an arm64 CPU that looks pretty awesome for our needs.
- AMD Opteron A1100 codenamed “Seattle”, 64-bit ARMv8
- Up to 8 ARM Cortex-A57 cores (64-bit)
- Dual DDR3 or DDR4 DRAM channels (4 slots possible)
- 128GB maximum memory
- Dual 10G Ethernet onboard
- 8 lanes of PCI-Express 3.0
- 8x SATA 3 ports integrated
- Integrated crypto and compression acceleration
- Integrated management functionality
- 28nm process initially produced by GlobalFoundries.
- Specs
- Comparison to Intel Avoton
- The Register article
- AMD Dev kit
- Group in Debian hoping to produce an ARM laptop using it, by making a board that fits in an existing Lenovo X-class case (and uses it’s screens/batteries/modules/etc) www.vero-apparatus.com
Low power CPUs¶
This table is focused on getting the best CPU for amount of power and cost and assumes RAM and I/O will be sufficient. If you need better memory bandwidth and/or more I/O slot bandwidth, you’re going to have to pay the premium for the fancy CPUs (that’s why they cost more).
Mainly these are “server” CPUs because they have more cache and memory channels.

Desktop CPUs¶
These are “Desktop” only in the sense that they are marketed for Desktop and a cheaper price (at the cost of cache usually). In most cases it makes more sense to get the above “server” models, but if these are good enough and price is an issue, maybe these are interesting?

- no need for 4 gig ports => drop the LN4 ones
- need IPMI: drop those without “F” in the name

- need >= 16 DIMM slots for interleaving
- no need for SAS

Some things to consider about short chassis
- Short cases don’t have rails, so you’d have to unscrew/rescrew them each time you needed to access them, or come up with some sort of short rails to slide them in on.
- Maybe it’s not as important to have hotplug for SSDs, hopefully they don’t fail as often (but if they are fixed, that compounds the above problem
- Rear I/O on short cases might be a pain as the cabling would need to be way forward in the rack
- Front I/O would let us mount cases on both sides, although we’d need a way to reach the power cord. Supermicro doesn’t seem to have a Front I/O case with power on the front too. (but we could use a picoPSU)
- In order to get a hotplug disk on the I/O side of a machine, we could use one of the PCI slot adapters listed below.
- I asked supermicro and the cases aren’t designed to move the mounting brackets to the other side in order to turn a Rear I/O into a Front I/O style machine. We might still be able to do that if we weren’t relying on those tabs for holding the machine up.
- I mailed Supermicro to ask about the 503* compatibility with the Atom board and X8SIL (Ibex Peak) board that we are interested in using, I’ll update when they reply.
We’re not super happy with any of the above, here is the ultimate case we’d build if we could.

Notes¶
- backblaze.com is cloud storage company that designs and builds their own chassies that hold huge amounts of inexpensive drives. They have a blog where they document all sort of interesting things: HDD failure rates, experience with 6tb drives, what SMART stats they monitor. Keep in mind their workload is bulk storage, they are using doing large block streaming reads and writes. But their data about drive failure rates is still interesting.
- Anandtech.com has an HDD category with good reviews.
- This page in anandtech’s 4tb review has good descriptions of the various vendor product lines.

SSD Disks¶
(These notes are old)
They are getting affordable for the small ones. Blazing fast, might be good for certain workloads. You can get decent 30-40gb drives for $100-120 now. You can get cheaper in other brands, but you have to be careful which controllers they have, some really suck.
Here’s what I have determined from reading a ton of articles:
- Of all the early SSD drives, most lost performance over time. Some you could get back to new performance by using a reset utility that told the drive to start over. Intel solved this problem first with their 2nd generation drives.
- Early SSD drives had limitations on the number of write cycles the flash could do, such that you might actually run into it. Modern controllers/firmware and improved flash in newer generation drives mean you won’t realistically ever run into this problem.
- There is an ATA command called TRIM that tells the device when a block is considered no longer used by the O/S and allows the drive to recycle it, thus helping prevent the lost performance over time problem. Support for this in Linux doesn’t show up until 2.6.33. I don’t know if it works with MD devices, probably not? For now we shouldn’t count on needing TRIM support for a drive to work well, better to pick drives that don’t have the problem.
- Intel made the best SSDs for the first couple of generations and their stuff is still solid although currently not the performance leader and not the cheapest per GB. It’s been a while since their G2 stuff was released and while it was the fastest when it came out, it’s not anymore.
- All drives of a particular SSD generation&brand use the same controller and NAND chips, and the controller is designed to support a certain number of chips, which is the max size drive that generation/brand support. They make smaller sizes by not fully populating the drive with chips. The NAND chips are accessed in parallel, so the largest drive is the fastest and it drops off as you get smaller. However even the smallest size is way faster than HDDs.
- The Indilinx controller mostly sucks, we should avoid it.
- SandForce is a small company that makes a controller used by several vendors including OCZ and Corsair. The current controllers are pretty awesome and the next generation is insanely awesome. Here’s a couple articles.
- One of the reasons Sandforce is so much faster in benchmarks is that they use this “durawrite™” algorithm to reduce the writes they need to do to NAND by doing compression and deduplication of data. But if your data is more random (like with O/S based encryption) then it loses the benefit. This new AnandTech review (of a drive that’s not that interesting) includes graphs and data of many drives being tested with random data. Here’s another review that also mentions the random data issue. His conclusion is that a SF-1200 with random data is slower than the other Intel/Indilinx offerings available (but he’s talking higher end). It’s unclear how they would compare to lower end stuff like the Intel X25-V.
- Intel’s 3rd generation using 25nm flash is expected in Q4 2010 – Q1 2011 and will be quite a bit better than their G2, but only on par with Sandforce’s current stuff and slower than Sandforce’s next gen stuff.
- This article about Crucial’s RealSSD C300 product, which uses a Marvell controller, says that it’s fast but that it has a problem with performance degrading after the drive has been used a lot. We should avoid it.
- Intel dropped prices on the X25-M G2 line on Nov 11, 2010 and also introduced a drive in the middle of the line. Unclear how/when this will affect the X25-V drive.
- Of the SandForce partners, OCZ has an exclusive deal for the Vertex 2 drive where it’s firmware is better at small random writes, the Agility 2 doesn’t have this and also writes are capped at 50mb/s. Corsair somehow is shipping this faster firmware (3.0.1), but future versions will likely add this crippling.

General info¶
comparison of Intel 520/330/335
Information about SSD "spare area" – the cool thing is that you can adjust spare area by just not using part of the drive. This could be done by making the partition table smaller than the whole drive. This would increase write performance, make performance more consistent, decrease write amplification, decrease writes which would increase the life of the flash.
Flash endurance, and another
m.2 drives¶
m.2 is a mini card PCI Express form factor. The cards come in various lengths and it’s being used for wireless cards, SSDs, and a bunch of other things. Some newer systems have built-in m.2 slots, but you can also buy PCIe x4 adapter cards (which are pretty simple, just rerouting the PCIe lines, no logic on the card).
The most interesting m.2 devices are SSDs that speak PCIe x4 which is a big increase in bandwidth over SATA 6g. The Samsung XP941 m.2 SSDs are marketed as being capable of:
Capacity | 128GB | 256GB | 512GB |
Sequential Read | 1000MB/s | 1080MB/s | 1170MB/s |
Sequential Write | 450MB/s | 800MB/s | 950MB/s |
4KB Random Read | 110K IOPS | 120K IOPS | 122K IOPS |
4KB Random Write | 40K IOPS | 60K IOPS | 72K IOPS |
Here is a good anandtech article with m.2 background and review of the Samsung XP941.

RAM¶
LRDIMM¶
There exists a new thing called Load Reduced DIMMs (LRDIMMs). They are for putting tons of RAM in the system (but at a slight latency cost). Currently 32gb and 64gb LRDIMMs are available, allowing a system with 16 slots to have 512gb or 1tb. More about them: 1 2 3

Laptops¶
Laptop as primary computer¶
Some people choose to use a laptop as their primary computer. For them, durability, screen size, and performance are much more important than cost.
FIXME: Someone other than taggart will need to write this.
On a sort of related note, dkg’s TrustedPhysicalConsole might be relevant here (and also below, but more so here).
Laptop as cafe network terminal¶
If you primarily use a powerful desktop at home and just need something to let you do some basic things while out at a cafe or on trips, portability (size and weight), “good enough” performance, and battery life are more important than durability, screen size, high-performance. It’s probably not as tricked out as the above, isn’t used for all tasks, probably doesn’t hold crypto keys, and is mainly a way to securely access “real” computers. It probably doesn’t hold any unique data for long periods of time, just checked out git trees that are also elsewhere, etc.
I (taggart) have been using an Asus eeepc (10" screen, Atom CPU, 2g RAM, 6h battery) since early 2009 and it’s still more than fast enough to run a bunch of terminals, a web browser with a couple dozen tabs, play music and internet videos, run git, etc. However, there are some similar but much newer things available. Here are some notes I’m taking to help decide.
