SoftIron's strategy to bring Ceph storage to the masses: 'A really, really sh*tty computer'...

talk_is_cheap

"For starters, it reverses the traditional storage server layout by moving CPUs to the front of the PCB and storage drives to the back. This means cool air from the fans blows over the drives first, and then the CPUs – which wouldn't make any sense in a compute server."

Such a configuration does not make any sense as data centres are often configured as cold and hot aisles where the front of the equipment (air intake) is installed facing the cold aisle and the rear (air exhaust) facing the hot aisle.

From the few photos on Softiron's website, this seems to be a misunderstanding by the reporter as there is a photo showing drive storage behind the front panel and the motherboard at the back of the system.

Up the stack with you: Microsoft's Denali project flashes skinny SSD controllers

I guess the Linux world will have fun with this.

By the time that the zfs team and one day an improved Btrfs team start to develop to arrays of such SSDs we may/will see some nice advantages from moving parts of the stack to the OS and main memory. As for Microsoft, all I would expect is a lot of work to tie systems to their OS while they would not make the investment in their file systems to take full advantage.

No because devices will still move between locations, each of which will be a different IP network.

The players who are left in this market can just claim that any expansion plans will take far too long to deal with cost issues during this market cycle - so extending the cycle. Unless one of these announces a major investment none of the other have to bother. It's hard to prove the operation of a cartel if all the producers just sit on their hands because no one has made a commitment to expanding their production.

Wikibon drops bomb, says Intel's Optane could be a flop...tane

We are still waiting for the 'real' product

Currently, all Intel seems to have to show is a 32GByte stick that is aimed at caching. Something of a dead end product considering the performance caches of many U.2. sticks are now larger.

The original pitch for this tech was 256GByte memory modules for installation into large fat servers where each Intel CPU could address 8+ memory sticks. The possible resulting I/O was meant to interest the big data and VM markets.

Today I wonder how many designers are more focussed on what they can do with 2 AMD top end processors and 128 PCI 3 lanes - that's a lot of 2TB U.2. sticks without paying premium rates to Intel for a lot less storage capacity.

PCIe speed to double by 2019 to 128GB/s

AMD interconnects

It starts to become very clear why AMD is happy to just use PCI links as its interconnects for its new server chips. Currently, the design uses 64 PCI 3.0 links to connect 2 processors which is as far as their published designs go. With PCI 5.0 they could greatly increase the overall interconnect speed or allow a 4 processor design using 16 links* between each with the same overall performance as now. I guess PCI 4.0 will provide a shorter term compromise with 4 possible processors connected at a higher overall speed, but lower processor to processor speeds.

* A 4 processor system would only need 48 PCI links (16 to each of the other 3 processors), this would allow the possiblity of hyper-cube designs (many processors not directly connected to each other) if AMD designs the correct protocols for cross processor communications.

The real kick in the teeth is the contract term.

M.2 SSD drive format is under-rated. So why no enterprise arrays?

talk_is_cheap

So why no enterprise arrays

One rather key issue is that you are talking about the 4x PCI standard, with the latest devices being able to fully load the 4 PCI lanes in test conditions. Such performance is able to overload 10Gbit ethernet links and saturate a 40Gbit link. This in many ways just makes them too fast for use in large arrays. Why bother if you can just deploy current SAS based options.

5 of them placed on a 16x PCI could make a nice RAID 5 solution, but will need a very high performance control chip to be developed, with performance specs well beyond anything currently available. For every 1GB/s of write performance the controlling chip will have to also read 1GB/s from the array, xor it and then write the resulting parity information as well as the original data. While such a configuration may provide very high speeds the enterprise market seems to be more focussed on DIMM based SSD solutions which link directly to the server's CPUs. These remove the controller chip issue and will distribute the storage across all the CPUs in a system if required.

The other great use for these types of drive would be as caches within arrays built with slower storage devices, but currently the write endurance is not designed for such tasks. The 960 PRO 2TB only has a 1.2PB endurance, which is not much in a enterprise write cache deployment.

Quantum is shutting down sync'n'share biz Symform in July

I used this sevice for a year or so, but

Even before Quantum purchased Symform the writing seemed to be on the wall as it had a wide range of limitations that did not seem to be getting addressed. Once Quantum was in charge it got even worse as nothing happened.

I moved across to hibiC, which does the job of syncing files to the internet and between systems at very low cost. So all in all its good enough.

Intel, Warner lock horns with hardware biz over HDCP crypto-busters

Where's the rest of this pirating solution they're claiming everyone uses.

Due with the new graphics cards from AMD and Nvidia as we will all need some way of quickly re-encoding an uncompressed 4K60 data stream that has been captured by some yet to be released capture card that can handle a ~2GByte per second hdmi 2.0 data stream. There will also be the need to store the data stream to disk, so I guess rather a large and fast SSD sub-system will be required.

Research: Microsoft the fastest growing maker of tablet OSs ... by 2019

talk_is_cheap

2 things

To become the " fastest growing tablet computer maker by 2019" you just need to make very few devices at the moment and then double your output. The result is 100% growth, which is hard for any major player already in the market place to match.

As for Windows 10 shipping on tables I think that will depend more on Intel's luck with their Atom chips than anything MS does. Most Chinese manufactures seem very happy to dual boot their Atom based devices with Android and Windows 10 as MS is currently giving away Windows 10.

The Internet of Things becomes the Game of Thrones in standards war

talk_is_cheap

This is last year's war.

All the current standards are designed to cope with the limitations of the CPUs and memory available at the time the standards were first put together so they all have profiles/sub-sets to keep processing power and memory requirements down.

These limits are being removed as new SOCs provide better CPU core/s, RAM and storage, so it becomes easier to deploy more capable control software that will be able to support things like TCP/IP stacks.

The results could be that all the current standards become little more that low power/low speed alternatives to the standard WiFi options.

As for Z-Wave its a nice 'standard' but you spend all your time trying to match devices to the different controller solutions as not all profiles/devices types are supported by all controllers. There are also very few easy to use programming libraries to allow you to just do your own thing due to its licensing structure and the fact that everyone is selling devices rather than tools.

Nakivo: Yet another VMware server backup biz going bananas

I've just installed it at a client site

It's not perfect, but it does everything that the client needs - backup, restore and file access. It's also got the right pricing model. The Client uses VMWARE ESX essentials across 3 servers, each of which has a single CPU. Most backup vendors want to charge for 6 CPUs and the resulting price of their backup solution is many times the cost of ESX.

Traditional RAID is outdated and dying on its feet

talk_is_cheap

Re: Eh?

>> So how are they going to rebuild a 4TB drive in minutes?

You don't, but if you move the RAID from the physical device level to the file system block level, you don't rebuild the single drive. What you do is spread the file system blocks that would have been found on the failed drive across all the remaining active drives (excluding the drives that already contain the block). For object storage you just do this at the object level, rather than the block level.

I'm not sure why IBM think that this is 'new' news as its a feature of a number of file systems already.

The wonders of tenders

The contract is to run for 2 years, can you imagine all the setup costs that have to be included in a 2 year contract to support 1/2m accounts and that's not including the capital cost of systems if the system can't just be deployed to current cloud services.

The only real winner is going to be Microsoft yet again via all the licence fees they will be charging.

AMD tries to kickstart ARM-for-servers ecosystem

talk_is_cheap

The key thing missing from this report.

One key market changer with this chip seems to be the amount of memory that it can directly address. At 128GBytes this is way above entry level Xeons (32GBytes) or new new Atom processors (64GBytes).

Intel may not lose sales, but they may have to reduce their margins a lot.

AMD starts year, checks watch, hurries out Warsaw Opterons

talk_is_cheap

Re: So...

The claim is that the Warsaw core is about 20% faster, clock for clock. If so you will see better overall performance, even if the top speed has been dropped. Also on a loaded system it's unlikely you would reach the turbo core speed, so the normal rated speed is what many users are looking at.

Top Microsoft bod: ARM servers right now smell like Intel's (doomed) Itanic

talk_is_cheap

I read that more as

We don't have any form of server OS for ARM, so need to kill the idea of it being a platform until we do, or in the hope that it will just go away.

ARM needs 64bit, ECC and some general interface standards to become a central server CPU, but to say that it has no place in a data centre due to other issues is a bit missguided. Rather a lot of devices and controls found in a data center are ARM based.

It reminds me of about 10 odd years ago when an MS rep was telling me that there was no real place for Linux in a data center.

Flexible flywheel offers cheap energy storage

Re: 15KWh?

The problem is that basic lead acid batteries have a very poor duty cycle as they do not like to be discharged. The result is that you have to build a setup where you do not discharge the batteries to much before you charge them up again. For a basic car battery its best for the discharge to be no more that a few percentage points. For batteries that do support depth discharging its still best to only discharge by about 50% if you want to get the most life out of them.

So it you want 15KWh of battery capacity you need to install 30KWh+ of batteries.
