Nec unveils express 5800/51mb workstation

October 21st, 2010

NEC has just released a new Workstation that looks very old school.

Dubbed as NEC Express 5800/51Mb, this workstation is not a stuff that you can judge from its appearance.

Practically, NEC 5800/51Mb workstation is capable of holding an Intel Core 15-520E or Core 17-610E CPU, total of 8GB DDR3-1066 RAM, SSD ready with RAID 0 HDD or RAID 0 SSD setup, and a built-in Intel HD graphic processor.

It’s small, but powerful. NEC Express 5800/51Mb will retails for 220,500 Yen or about USD $2,000+.

Avadirect clevo x7200: six cores, ssd raid, and gtx 480m sli yields world’s fastest dtr notebook

October 7th, 2010

I undertook a new exercise and fitness program. It’s one of those high intensity workouts that can really burn through the calories, and in just one week I dropped 20 pounds! So what is this new wonder fitness regime and what does it have to do with computer hardware? Let me introduce you to my weight set…

All kidding aside, let’s get this out of the way: the Clevo X7200 is an absolute tank, weighing in at 12.1 pounds for a basic configuration with a single 480M GPU. We see little point in buying such a high-end product and only getting the basics, though, so AVADirect loaded us up with what is easily the fastest piece of portable kit this side of 2011. Dual GTX 480M is only the starting point; for the OS and performance-oriented applications, they RAIDed a couple of Crucial RealSSD C300 256GB SSDs together, then tacked on a Seagate Momentus XT 500GB drive for mass storage. All told, we’d put the weight of just the notebook and battery at close to 13 pounds, and then there’s the power brick.

How’s that for a monstrous power brick? Previously, the biggest notebook power adapters topped out at a “measly” 250W output. This bad boy can put out a full 300W (and perhaps a bit more peak power). It’s also heavier than a typical netbook, quite a bit thicker, and brings the total package weight to around 16 pounds. Thankfully, you don’t have to worry about finding an appropriate notebook bag, since AVADirect/Clevo is kind enough to include one. It’s an inexpensive cloth case, but it will get the job done until you shell out for something nicer.

None of this is surprising, since we’re dealing with the new flagship product from Clevo. But some things have changed—and definitely for the better—like the aluminum surfaces replacing the (typically glossy) plastic we’ve seen in previous models (M98NU, D900F, X8100…). The X7200 manages to pack more performance potential than the previous generation X8100 into a slightly smaller chassis, and it upgrades the build quality and aesthetic at the same time. It’s still big, heavy, noisy, and can run a bit hot under load, but this is without doubt the nicest looking Clevo notebook we’ve ever seen. Let’s give a quick overview of AVADirect’s test system before we continue.

Like we were saying, this is the highest of the high-end for desktop replacements. The CPU is the fastest option around on a desktop; sadly, there’s no overclocking support from AVADirect just yet, but that might come later. Even without it, the 980X is easily 50% faster than the top mobile CPU. The i7-940XM is a quad-core Clarksfield clocked at a base 2.13GHz and can turbo up to 3.33GHz; the i7-980X in contrast is hex-core with a base 3.33GHz clock and turbo up to 3.6GHz. If you’re after multi-core number-crunching power, this is as good as it gets.

The dual GPUs pack a whopping 4GB of combined GDDR5 memory, with 352 CUDA cores clocked at 850MHz. If you’re after a comparison to the desktop world, we’ll have that later, but the sad news is we’re still substantially slower than the top desktop GPUs. GTX 465 comes with the same 352 cores but clocks them 43% higher; likewise the GPU core is clocked at 607MHz versus 450MHz on the 480M. Finally, memory bandwidth is 102.7GB/s on the GTX 465 compared to just 76.8GB/s on the 480M. The net result is that 480M performance looks to be faster than desktop GTS 450, but slower than GTX 460 and above. And there’s the price to consider as well: while desktop GTX 460 starts at around $170, AVADirect charges $756 to add the second GTX 480M. Yes, it’s mobile and has been binned for lower power, plus it comes with 2GB of RAM instead of the 768MB on the GTX 460. However, lots of video RAM goes largely unused unless you have the GPU core processing power to back it, and 480M simply doesn’t. And we’re still looking at a TDP of 100W per GPU…yeah, it’s a bit curious to have a 130W TDP processor and two 100W TDP GPUs—plus various other components—all running off a 300W power brick. We’ll look at this more in a bit.

So $1000 for the CPU, $1500 for the GPU, and since we want the best of the best, we’ve got RAID 0 SSDs. Honestly, the Crucial C300 isn’t our first choice for SSDs; that honor goes to the SandForce SF-1200 controller SSDs, as they’ve shown themselves to be more resilient and slightly faster overall. In RAID 0, there’s no TRIM support so you’re left to depend on idle garbage collection by the SSD. Anand’s tests indicate that the Crucial C300could be a lot more aggressive here. Compare that to the SF-1200 garbage collection and you’ll see why we prefer the latter. AVADirect tells us the C300 RAID 0 scored slightly higher in their testing than the SF-1200 in RAID 0, but long-term we’d still recommend anyone looking at RAID 0 go with a more resilient drive. The performance drop may not come immediately (we bombard the SSDs with a lot of random writes to get to the degraded performance level), but eventually all SSDs will have enough random writes that we expect them to run like the torture tested “degraded” SSDs. As for cost, Crucial C300 does have an advantage there: 2 x 256GB adds around $1072 to the total price, whereas 2 x 240GB SF-1200 (OCZ Vertex 2) would bump the total price up $1194. But do you really need to save $120 on a $5000 piece of kit?

The sundry extras consist of the usual suspects of networking options, webcam, audio, fingerprint scanner, a decent quality 1080p LCD, and a Blu-ray combo drive. There are also some features we don’t see quite as often, like the two USB 3.0 ports on the left side. AVADirect also maxed out the current RAM configuration at 3×4GB for 12GB total DDR3 memory. (They’re working to get 8GB SO-DIMMs in the future, though we’d only recommend such an upgrade if you’re interested in a mobile server/workstation.) As configured, the system we’re reviewing with a 1-year warranty comes to a total price of just under $5800. Again, that’s $1000 for the CPU, $1500 for the GPUs, and $1100 for the SSDs. The basic setup with a single 480M, i7-930, 3×1GB RAM, and a 500GB 5400RPM Samsung drive starts at $2700, while if you go for a “reasonable” SLI configuration with a 500GB Momentus XT, Blu-ray reader, and 3×2GB DDR3 you’re looking at $3700.

Eurocom launches raid 10 notebooks with vertex 2 ssd

September 29th, 2010

Eurocom. You know the name.

They’re one of the most prominent gaming notebook makers on the planet, and their machines are generally larger and faster than anything else out.

The company has just announced yet another innovation, with the launch of RAID 10 notebooks that utilize the quick 480GB OCZ Vertex 2 SSD, a drive powered by the SandForce 1200 controller.

That Vertex 2 drive will soon be available in all Eurocom Mobile Workstations and Mobile Servers, offering up to 250MB/sec on the read side and 240MB/sec on the write side.

The drive will be available in the Panther 2.0, X8100 Leopard and three other major machines soon, and we hope that this is just the beginning of using ultra-fast SSD units within gaming notebooks.

Trust us, we could all use the speed!

Patriot Convoy puts a RAID array into your PC

September 29th, 2010

When it comes to memory for your computers or SSDs to store your data on Patriot has you covered. What some of us need is a way to store more data inside some of the unused optical drive bays on a desktop computer. Patriot has you covered there too with its Convoy line of storage devices.

Patriot has added a couple new products to the Convoy line today that have four 2.5-inch drive bays. The new products are the Convoy 425S and the 425XL and both are very similar. They have an aluminum chassis and 40mm fans to keep the drives inside the hot swap bays cool.

Those bays will hold any 2.5-inch SSD or HDD that is 12.5mm or under in those bays. The difference between the two is that the 425XL supports hardware RAID 0/1/3/5/10 JBOD. Patriot says that the 425XL hit 240K IOPS when using Patriot Inferno SSDs inside.

Amd to introduce bulldozer-compatible core-logic sets in q2 2011.

September 25th, 2010

Advanced Micro Devices plans to introduce its new 9-series chipsets that will support the forthcoming code-named Zambezi processors featuring Bulldozer micro-architecture as well as input/output memory management unit (IOMMU) in the second quarter of 2011.

The new breed of chipsets will be a part of AMD Scorpius enthusiast desktop platform.

Although there will be several minor differences between AMD 8-series and AMD 9-series core-logic sets, the main two features of the new Scorpius platform will be support for new Bulldozer micro-architecture processors as well as IOMMU, a technology that will bring a number of new features to AMD’s desktop platforms and will differentiate it from competing offerings from Intel Corp., according to people familiar with AMD’s plans.

Like a traditional MMU, which translates microprocessor’s virtual addresses to physical addresses, the IOMMU maps device-visible virtual addresses to physical addresses.

The I/O memory management unit provides a secure, scalable, high-performance solution for I/O virtualization in client or server computers.

While it is clear that IOMMU sports a number of advantages in server platforms and virtualized environments, its main advantage in desktop platforms will likely be improvements in heterogeneous computing.

While there is no concrete guidance at this point, but it is highly likely that all mainboards powered by AMD 9-series chipsets will feature AM3+ sockets that will support AMD’s code-named Zambezi desktop processor as well as current-generation AM3 chips.

The mainboards will possibly support numerous innovations beyond AM3+ and IOMMU and given the fact that the new chipsets will have new clock-speed generators and the Zambezi chips will support Turbo Core 2.0 technology, there will possibly be a number of new options for overclockers.

Even though AMD plans to start shipping its 9-series chipsets in Q2 2011, it is still unknown when the company is able to ship its desktop microprocessors known as Zambezi made using 32nm process technology.

There will be three versions of AMD 9-series North Bridges that will be slightly different from each other:

* AMD 990FX – supports two PCIe 2.0 x16 slots (configurable as four PCIe 2.0 x8), six PCIe 2.0 x1 slots, one PCIe 2.0 x4 slot, to be paired with SB950 I/O controller;

* AMD 990X – supports one PCIe 2.0 x16 slots (configurable as two PCIe 2.0 x8), six PCIe 2.0 x1 slots;

* AMD 970 – supports one PCIe 2.0 x16 slot, to be paired with SB950 and SB920 I/O controllers;

AMD 9-series south bridge chips will support the following:

* AMD SB950 – four PCIe 2.0 x1 slots, 14 USB 2.0 controllers, PCI bus, six Serial ATA-600 connectors with RAID 0, 1, 5, 10 support;

* AMD SB920 – two PCIe 2.0 x1 slots, 14 USB 2.0 controllers, PCI bus, six Serial ATA-600 connectors with RAID 0, 1, 10 support;

Advanced server setups

September 24th, 2010

When it comes to upgrading your server you may want to consider buying and building a new one from scratch, because your old server could offer some redundancy if either of them were down.

If you business relies on being connected to the internet or your phone system connects through your server, then you really want to be able to have another server kick in if the one goes down.

Active directory resources will continue to be available to users on your corporate domain as well, provided that which ever server you are using as a backup is an exact mirror of the other.

This effectively means there will be no downtime for getting the server back up again, and your company won’t lose money through missed sales etc.

When buying the parts for a new server, you must consider carefully what exactly it is going to be doing most of the time and what you need it to do.

For high speed bootups and fast access to expendable resources (like installation files for common programs), then you might want to invest in a good quality SSD drive.

I mention expendable resources because you would not store user files on this drive because SSDs have a shorter life span than traditional rotary drives.

Important files and user data would be stored on two or more rotary drives in a mirrored RAID array.

This make it so if one were to fail, the data would still exist on the other as a backup.

The reason you would want to put your operating system on the SSD is that this will allow you to start your server up faster after a crash and allow your users to work with files on the server much faster.

Many believe that having SSDs in RAID-0 will give massive performance improvements but they are sorely mistaken!

It is much better to invest a little more into a SATA3 SLC SSD. That is a single layer solid state disk that is much more reliable than MLC (multi-layer cell), they are also slightly faster.

Many companies believe that you must keep your server in an air-conditioned room.

This is a very easy but extremely expensive option to keep the hardware cool.

Another option exists and that is to have everything cooled by water.

A powerful water cooling system would cost between $400 and $600, perhaps more depending on your server setup.

That compared with an air conditioner which can cost over $4000 including installation makes it seem like a much better option!

The cost of running a 12 volt pump is also significantly cheaper than running a 1kw cooling solution 24/7!

A water pump is also more reliable than an air-conditioning system, and if something were to go wrong with it, it is simply a matter of replacing the pump which is only a 5 minute job if you have one on hand.

An air-conditioning system could be down for weeks which is bad news if your server over heats easily!

How to choose a raid controller

September 20th, 2010

Step 1. Know what you are using it for.

Ask yourself these questions. How big of a capacity are you looking for (Terabyte)? How fast do you need the performance to be? (are you using it for server or video editing) and the ultimate questions, how much money do you have?

Only by answering these questions, you can locate the RAID controller for you! Now start the meditation process and find these answers in your heart. Here are a few facts that might give you some insights.:!:

- Current largest capacity SATA and SAS hard drives are 2TB, so with a four port controller, you can easily reach 8TB of RAW storage.

- Any “Areca” controller with four hard drives could easily pump out 300+mb/s which is sufficient for any HD or 2K video editing/rendering work.

- With eight hard drives, you are looking at 700-800mb/s SUSTAINED, which is sufficient for 4:4:4 uncompressed materials. (its actually an overkill) No burst performance or marketing crap being mentioned here.

Step 2. PCIe RAID controller or RAID subsystem?

What the hell are RAID subsystems? You might ask… RAID subsystems are enclosure with RAID controller built into the box which has combination of eSATA, USB or Firewire as connection interface to your computer.

The major advantage of RAID subsystem is that you can choose the interface you think will be most suitable with your current machines.

However, the biggest drawback is that you do not get as much performance with RAID subsystem compare to PCIe RAID controller due to data transfer rate limitation on each interface.

If you like your storage moved between multiple different machines (including laptop), you will find RAID subsystem much friendlier to work with as you usually get multiple different interface options and they are mostly plug and play like USB thumb drives.

On the other hand, if you need hardcore performance for your stationery editing machine or server, you’ll be looking at PCIe RAID controller which delivers much higher throughput.

If you have decided to go with RAID subsystem, you are pretty much done as you just have to pick the box with preferred number of bays, and included interface.

One note when picking RAID subsystem is to make sure the box is integrated with hardware RAID (like all Areca subsystem) as it will become a major difference when volumes become degraded.

Step 3. SATA or SAS hard drives?

All RAID controllers in the world can be separate into these two categories, the major differences has been compiled into the table below. Unfortunately, there is no SAS HDD option available for subsystem.

Therefore, if you have decided to go with a RAID subsystem solution, you can skip this step and just fill them up with SATA hard drives.

*****SATA RAID controller******

- Slow performance

- Cheaper in price

- SATA controller can only take SATA drives

******SAS RAID controller******

- faster than SATA

- more $$ than SATA

- SAS controller can take both SATA and SAS drives

- Some higher end SAS controller support SAS-expander, which allows you to expand up to 120+ drives.

Step 4. Do I want these hard drives to be internally or externally attached?

Unless you have a rack mount, normally you want to go with a separate external chassis to hold all the hard drives for better air ventilation and sufficient power.

There are all kinds of different chassis to be found cheap on online retailers but the trick is to find one that is guarantee to be compatible with your controller!

There is nothing worse than finding something isn’t going to work together after you have bought everything.

A few recommended chassis that are compatible with Areca cards are CineRAID or Sans Digital, which can be found on newegg.

Step 5. Price

Now with all factors considered, it eventually comes down to price. If you are looking for cheapest RAID controller ever, Areca will not be your cup of tea.

You can head straight to search Highpoint or left over 3ware RAID controllers who are known to be making the cheapest RAID controller in the market.

For higher performance and reliability, you will have to pay a higher price for it.

(Oh, Snap!) If you are really poor, you might simply go with software RAID emulator that comes with the motherboard or any standard operating system.

They are free but the trade off is they will drain your CPU and memory at all time.

The entry level Areca controllers are 12xx series while the higher end model SAS controller are listed as 16xx series.

The price ranges from few hundred bucks to over a thousand bases on the amount of memory and CPU that is equipped on it.

Please note the 16xx series controller has SAS-expander support which gives you the option to ‘grow as you go’ in capacity.

If you manage to finish reading these five steps, you are now in good position to look at the massive Areca product catalog and choose the right RAID controller that best suites your need.

The table below is an Areca PCIe product matrix that will help you locate the exact model number.
