I just noticed Microsoft Windows Storage Server 2008 was listed in my MSDN downloads. I've never actually seen this product. Has anyone used it? Any thoughts?
I am currently on Openfiler which is probably the best Linux based NAS. (I know of FreeNAS). Openfiler's is solid once it is up and running, but the documentation is sparse and the developers are pretty grumpy and very fast to tell you your hardware is the problem and it "works on my machine"

I sent memorydepot.com an email asking about these drives, how many erase cycles and if they use a wear leveling algorithm, I got a great response
The endurance: 2,000,000 Program/Erase Cycleswe do have a wear leveling algorithm,
It is explained on the attached specsheet, but don 't hesitate to contact me
if you have any additional questions.
Best regards
Fabien
Most plug them in usb drives have less erase cycles but I am having trouble finding specifications documents. Anyone have any concrete numbers? I tried to attach the PDF he sent me but it looks like the forums block it, let me know if you really woudl like to see it.

Forgive me if this question seems dumb ...
In the ESXi episode, Matt and Darren used a USB thumb drive/memory stick (call it what you will) to load the host OS and this was attached to the motherboard via a lead. I've been contemplating doing something similar and found this.
I'm not sure what the performance difference would be between a DoM and the methodology that Matt/Darren used. I understand that USB flash drives/memory sticks don't like repeated and frequent read/write operations. Is a DoM, in effect, a mini SSD mounted directly to a connector that can attach to USB, SATA or IDE on the motherboard?
Can you post a link and the time at which Matt and Darren do this? I am pretty sure I have seen the episode but my memory is hazy. I think what they did is they took a regular USB back plate and didn't screw it into the back of the case, they just let it hang inside.
The link to the product you posted is exactly the same as one I posted at the top of this thread. Using that versus Darrens method really isn't any different. It is just a bit more elegant because you don't have this wire dangling in there.
The biggest difference between the DOM versus the hacked internal USB flash drive would be what IOSys mentioned, this DOM are usually created to withstand a lot more writes. And I guess that is probably the answer to my question.
A DOM is just a flash/ssd based device that plugs directly into the motherboard.
-
You can also get DoM's that will fit into a IDE-slot on your MoBo and there are also SATA-versions available ..
Yeah I see TONs of those types. But my motherboard DX58SO as phased out IDE ports. I also have plenty of extra USB ports so I would rather use one of those over my limited six SATA ports. I guess I am going to just spring the $100 for a 8 gig one.
-
If that small little sucker contained a SSD built into it, the high price would defenitely make sense.
All flash drives, including the links to the ones I posted as well as the traditional USB plug in flash drives are SSDs.

I have been wanting to grab a USB Disk on Module for my ESXi server that I can boot the machine from and run ESXi from. My main motivation for this is to free up a SATA port.
For 8 gigs, it costs at least $100!

I am tempted to just grab a regular 32 gig flash drive and hook it up to a USB connector that will stay inside of the case. I haven't been able to find a ten pin to usb header adapter, just the ones on a cable that mount externally, but if such a thing existed that would be more elegant. (aha! found it http://www.newegg.com/Product/Product.aspx...ECH-_-12200474)
But what are the embdedded ones so expensive? They seem so handy.

That's not quite right. The host has priority, if the host wants to use all the CPU, it will and the VM will go extremely slow. If the guest wants to use the CPU while the host is also using it, the guest will, more or less, have to wait for the host to finish. If the host is not doing any thing, the guest will run at, more or less, full speed.
Dule core processor is essential for running virtual machines (even one, the more cores the better really).
You are correct, but for someone who is new to virtualization I don't think my explanation is a bad way to get a grasp on how fast your VMs could potentially run in their best case scenerio. Which is to say your VM will never run as fast or faster than your host machine, but it will always run slower than your host. If he is on a machine where memory is shared with the video card, I doubt he has a beefy CPU. In that case I wouldn't expect a VM to run at more than half the hosts power and that is probably the best case for him.

Interesting. What evidence links the neighbor to the emails?

All operating systems suck. They each suck in different ways so no one is really better than the rest. Choose the one that sucks the least for what you will be doing with it.
If someone gets defensive about their operating system then they are still in the honeymoon faze where the sucking is glorious, or they are just oblivious to the fact that their operating system is off sucking behind their back.

Hello I have Virtual Box running on an XP host and have a couple questions.
1) My VMs run slow, and I was wondering if there is any way to create virtual RAM for use with Virtual Box.
2) I hate starting a VM just to access a couple files, so I was wondering if there is a free, easy to use tool out there for mounting VDI files on XP.
You need much more ram. What type of CPU do you have? Some CPUs support an extended instruction set for virtualization, those CPUs are much faster.
Here is a way to think about it, how fast is your computer normally? Now cut that in half when you load up your virtual machine because it is sharing your resources. Is that about the speed your VM is running at?

What kind of network switch are you using?
I am trying to minimize hardware so I want to keep everything in one box, so no switch. I have a quad and a dual port nic so plenty of ports for my network. But unfortunatly it seems like using a switch is the answer if I want this sort of setup.
As far as I know a normal router cant isolate vlans by itself without the help of a switch and trunking. You can try setting a vlan on each workstation's nic, setting them to different vlans and groups of subnets, but ultimately if they are on one router IP Subnet, and no switch in between, then they all share the same network. The problem is once you seperate the machines into subnets, they wont be able to talk to the router unless they are on the same subnet and mask as the routers gateway address. Each subnet would need its own gateway address on the router itself in order for them to speak to the router.I'm not too familiar with ebox, but if you can configure individual ports to their own subnets and a gateway address for each physical port, then in theory you really dont need vlans since they will all be on their own subnets. This may however not be possible, by which you would then need a switch to configure true vlans, subnets and your router would need to be able to do trunking for multiple subnets on one physical port that is connected to the switch.
Thanks, this clarifies the behavior I am seeing. I have now configured each port to be on its own subnet and its own gateway.
Ok,, you want to put some firewall rules between you WLAN and LAN interfaces if you wish to control traffic between the 2 networks, as the router is just routing traffic between said interfaces. VLANs are just a way of extending a broadcast domain across multiple physical locations, IE having all of finance in 192.168.10.0/23 despite being located in 3 different buildings on your site.Thanks, Firewall rules seem to be working to block WLAN to LAN. Is there any security concearn if I leave LAN to WLAN open?

I am trying to learn more about networking and how to set up a network, specifically with VLANs. I believe VLANs are the answer to helping me bridge and isolate my network, but I am no expert on this topic so I could be way off.
I have mentioned else where I am planning on sticking with eBox as my router/firewall. I have a quad port intel pro 1000 nic. eth0 is WAN, eth 1 & 2 will be internal and eth3 will be connected to a wireless router in bridged mode. I have a very small number of wired machines so I don't want to have an additional piece of hardware just for them, I'd rather plug them directly into the router because I have the ports there. (I also have additional ports but I want to get a smaller base configuration working first).
In my first attempt I configured eth1 & 2 as 192.168.100.1/24 and 192.168.100.2/24 respectivly. I enabled DHCP (Yeah I know I could just use static IPs but I will also have VMs running on the client machines that I want to pick up IPs automatically) on eth1 to hand out IPs in the 192.168.100.100-199 range. When machines were plugged into eth1 & 2 they got an IP but could not ping anything. I learned this was because having eth1 & 2 on the same subnet resulted in a routing issue. The solution was to place eth1 on 192.168.101.1/24 and eth2 on 192.168.102.1/24. After this change routing works.
Now when eth3 comes into play on 192.168.103.1/24, clients are able to ping anything on the entire network, ie 192.168.101.0/24. So I thought the answer might be VLANs. My wired VLAN was going to be 192.168.110.0/24 and wireless 192.168.120.0/24. When I gave eth1 and eth2 VLAN IPs of 192.168.110.1 and 192.168.110.2 I ran into the same exact routing problems.
So it seems like I am missing a big understanding of exactly how VLANs, or something else, works. Can anyone enlighten me? Basically in the end I want my router to act as a switch and allow me to share connections between a few interfaces, but I also want to isolate other interfaces so they are on their own private lan.

So I a thought (o god the pain) XD any how could you attach another hdd to the smoothwall rig and get network storage out of it ? I mean you would probably have to modify something but has any one herd of this or seen an add on?
This is supported out of the box with eBox
-
Its a router, it sits there and routes traffic, other than that it doesn't really need to do much else. And once you set a router up, how often do you touch it? I would suggest that you at least try it, its a quality product.
Having said that, Vyatta is something I will have to try.
If I had more knowledge of FreeBSD it wouldn't be such an issue. But it is the one random occurrence where something will go wrong and I will know how to do something in linux but not freebsd that makes will frustrated to no end. This could be fixed with some learning, but I'd rather put that horsepower somewhere else.
Vyatta does seem to be the most enterprise of the bunch. There is also a product called ClarkConenct which I came across and it looked like it was a competitor to Vyatta, but I don't think there is a free/community version anymore. Or if there is, they hide it very well.
One little note about Vyatta that got under my skin, the word vyatta is suppose to mean open. I don't think it fits at all, I don't want my router/firewall to be open. I think they mean open in the open source sense, but the product isn't 100% open, more like 30% open.

It is a real shame that you don't want to look into PFsense, out of all the router distros I've come across it just seems to work for me, very stable and quite powerful.
Yeah I really wish pfsense was linux based because I have heard great things about it. Ultimately it comes down to me being stubborn. I know linux, I don't want to be bothered learning the subtle little differences like slices.
-
A few weeks ago I started looking into every linux based router distrobution I could come across. FreeBSD is nice, but I like to stick to Linux so that means monowall and pfsense are out for me.
IPCop is a fork of smoothwall and both IPCop and smoothwall haven't been updated in over a year. I also came across this article
http://neuro.me.uk/2008/03/05/no-more-smoothwall-for-me/
And that pretty much put the nail in the coffin. I really hate when politics get in the way of making software. So to answer your question, I haven't used Smoothwall for the past two years, but I don't think much has changed.
I very quickly looked into Vyatta but was dissapointed that it doesn't run on 64 bit hardware. That might be overkill for a router, but I am not living in the past, I have current hardware and I want everything to be 64 bit. Vyatta also seems to be highly targetted towards cisco replacements in enterprise environments. I decided to come back to Vyatta if all other distros fail me.
Then I found Untangle. It is being activly developed, it runs on current hardware and the community is great. They have a ton of free addons and some paid ones that would only be needed in enterprise applications. Then I found out if your configuration isn't in line with their ideal configuration setup (ie only one internal network) then you are pretty much out of luck. If you only have two NICs then Untangle might work for you, but any extra NICS are useless. I only have a few machines which will be on my wired network so I don't want an additional switch to mess around with. So Untangle is out for me, but it gets the thumbs up.
Now I am currently looking into eBox. This is an addon you install on top of Ubuntu. So far I am really impressed. It is being activly developed, has a decent (although slow) community and it seems to be the most open of all the other distros. You can take an existing install of Ubuntu and add a repo for eBox and install from there.

isn't an i7 kinda overkill? lol
Absolutely not. If I could have gotten a dual socket motherboard on the cheap I would have.

I am almost finished setting up my virtual machine server. In light of episode 7x17 I am curious if anyone else has a virtual machine server at home. Ever since episode 5x19 I have been wanting one of my own, and now it is almost complete. My goal was to create something as quiet and powerful as possible. Functionally I wanted a virtual router, NAS and a playground. I want to put it in the closet and forget about it. Here is what I have so far. Most of the items were bought from eBay to keep the cost low, other things have been recycled.
Case: Antec P182
Power Supply: Antec NEO ECO 400 Watt
CPU: Intel Core i7 I7-930 2.8 GHz
Motherboard: Intel DX58SO
CPU Heatsink: Noctua NH-D14 running with low power adapters
Hard Drives:
- 2x Seagate Barracuda 7200.12 1 TB 7200 SATA 3.0Gb/s running as a raw drive for OpenFiler
- 1x Western Digital Caviar Green 2TB SATA 3.0Gb/s running as a raw drive for OpenFiler
- 1x Really old Maxtor 160 GB SATA 1.5Gb/s running as main drive for ESXi
Memory: 2x Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1066 (soon to be 12GB, then 16GB).
Video Card: G55-MDDE32F Matrox Millennium G550 PCIe 1x
NIC:
- INTEL PRO/1000 PT Quad Port Adapter for Untangle
- INTEL PRO/1000 PT Dual Port Adapter for Untangle
- On board NIC for management
The next plan of action will be to replace that old Maxtor which is giving off a lot of heat with an SSD or if I can't get one cheap enough a traditional high speed drive. That should also be a huge performance boost. Then memory will get maxed out as prices come down later.
So far I have the following OSes running
-Backtrack 4
-Fedora 13
-Windows 7 (for .NET development and ESXi management since their interface is windows only)
-Untangle - once I get everyting configured properly this machine will be my router/firewall.
-OpenFiler - Network Attached Storage.
Next I will be adding Ubuntu Latest and Windows Server 2008 R2.
I have installed rdesktop on my regular desktop to access the machines and xrdp on the linux guests because it beats the pants off VNC.
If anyone is interested I can get some pics later.
For reference I needed to enable the unsupported ESXI service console so that I could map my drives as raw devices in OpenFiler, here are the tutorials I used.

ESXi is rocking out pretty great. I am jealous of Virtual Boxes build in RDP server through because I did have problems getting Fedora and sesman to play nicely.

I found the article http://blog.ust.hk/martinl/2009/03/25/smoo...as-nat-on-esxi/
But if there are any better alternatives I am open to them, thanks!

I know I have seen an article on this somewhere, but I can't find it, my google-fu is failing at the moment.
I have a machine running ESXi with one quad and one dual port intel pro 1000 pt nics. ESXi will host a number of guests including one routing OS. This was going to be smoothwall, but I am leaning towards Untangle at the moment. The nics are assigned to the routing OS as PCI passthrough devices.
I would like all of ESXi's guests (excluding smoothwall/untangle) to get IPs from the virtual smoothwall/untangle guest (ie all ESXi guest's network traffic will be routed through the smoothwall/untangle guest). How do I configure this?
-
If you have a virtual machine with enough network interfaces, there's no reason to purchase a whole new machine.
Smoothwall's resource utilization is extremely low, and I've deployed a good number of "virtual routers" on top of esxi.
Otherwise, you can get a barebones solution if you like, but there's no real advantageous reason to.
Sweet, thanks, this is the reassurance I was looking for. I am all about consolidation.

Sweet motherboard
... holy shit it's Matt Lestock. Been a long time man. How's it goin?On the other (main thread note).
I guess you could say it's a damned if you do, damned if you don't type of thing. Extra cost/thread use on that server for that one extra smoothwall vm, or extra cost for that extra computer.
If you'r that worried about the security side of it, go grab the cheapest dual core atom server you can find and use it for the smoothwall. TBH it's most probably cheaper if you build it yourself, but if you want a prebuilt solution, just newegg search for it.
I believe they are in the $300 to $400 price range,(no hdd/ram/front video or dvd/cd ports on the front). If you build it, you could probably kick it well @ around $300 flat for a low power, low memory machine. I mean how much do you really need/want smoothwall to do anyways?**edit**
here's your Rackmount box for $279.99 + Free Shipping (shit I am really thinking about buying this one myself.)

Kind of old, but, like all software, virtual machien software will have flaws in it, and ultimately the VM software is running on the host.
ESX hasn't been affected by these types of hacks, I think this is because ESX is a bare OS, nothing much to compromise.
-
I have a similar project of my own too. My server will have dual processors, 12 to 16 gigs of ram, a couple of SSDs, intel FCOE (Fiber Channel over Ethernet) network adapter.
It will be acting as a file server with 4tb of storage capacity in a raid 10 configuration, with a couple of VMs running as well. I also plan to implement other services like web server, ftp server and a database server.
Can you give me more hardware details? Links? Server Porn? Sounds like you are doing a real server, I was considering that, but I also want a relatively quiet, low power drawing machine.
For the purposes of security physical separation is always better.I agree, but so far in practice I haven't seen hacks which were executed solely because of virtualization, have you?

First, what is yoru network set up? Are you on a gigabit lan? What sort of router/switch are you on?
Also just as an FYI, for local transfers (ie not to the itnernet) your internet speed will not affect your NAS speeds.
