I have the N36L version of this box. Love it to bits for playing about on. Running ESXi 5 and yes the slowest thing in this box really are the drives. I have three discs and try to stagger my VM's across them so no disc is really doing too much work.

I've have had 1 x 2008 R2 DC, 2 x Exchange 2010 running on 2008 R2, 1 x Windows 7 and a Arch Linux. They run well as long as each one isnt under too much load (Disc I/O).

Anyone managed to get OSX working? Works fine on a machine in my office running an Intel CPU but on this Microserver it just sits with a grey apple logo. I figure its the AMD CPU and pretty much given up trying now.

Here is the ram I ordered -- cheaper, and have had not issues with it.

Looks like the price went up a couple of bucks.

Thanks! I can install vSphere 5 then now. Got it from the UK site however!

I just have to serve up the files via smb.. I don't have to transcode them on the fly or anything.. Just a simple file server, my popcorn hour plays the files in whatever format they are in.

So you were writing 3 different installs to the same datastore at the same time - and reading all from the same iso?? WTF yeah that going to be slow as hell! Why not just install once and then copy the install if you were installing the same OS?

Yeah, I used to have a Popcorn Hour but didn't like the UI. Will be migrating everything over to Raspberry Pi with XBMC/Plex shortly anyway. That said, I've not used a Popcorn Hour since 2008. I'm guessing they've improved somewhat since then? All I remember about it was power cycling it about 50 times a day.

I would think the NL40 is quite limited in regards to performance, it would only take a number of VM's for it to choke.

Well, the only VM thats really doing any work is the pfSense VM and the Sabnzbd/Sick Beard VM, running 6 total.

"it would only take a number of VM's for it to choke."

No **** ;) But you can say that for any hardware - the number of VMs you can run at the same time is just going to vary. And what those VM's are doing.

What I can dell you is it runs my router, and is running my file server, and my test box w7 and my linux distro. The file server, the router and the linux box are on all the time..

It is more than capable of handling the number of VMs I would ever need to be running at the same time, and allow for many many more to be available when I need them for play or testing. Allowed me to combine my file server and my router boxes into a tiny little thing - that looking currently at the killawatt meter its connected to is drawing 55.5 watts ;) That is with 4 disks in it. Its been on for 366 hours and has drawn a total of 20.3KWH, so I pay like 12.5 cents per kwh so your looking at $2.50 to operate for 15 days. So about $5 a month to have it on running all the machines I need to run or play with.

And for the price you sure and the hell can not beat it for a home esxi solution or even a small business setup. No I wouldn't expect to run my enterprise VMs on it ;)

Looks like I found a pretty big part of what was happening with the I/O problems too.

See the Disk I/O. Notice the drop, thats because one of my Hard Drives had some damaged sectors and ESXi wasn't marking them as bad on the fly, causing massive I/O and Error Rates, after yanking the drive it dropped massively and all VMs are running great now.

I have the N36L version of this box.

I have a N36L as my primary storage server, Windows Server 2008 R2, Software RAID5 across 4 Drives (2TB). 5.5TB Total Storage.

OS X runs fine with ESXi on a XServe / Mac Pro. But it doesn't even want to attempt a startup on this HP Hardware. Would require a hacked Kernel I think, and I wouldn't touch that with a bargepole!

If anyone needs discounts on any vmware stuff I can help since I am a partner.

Nice offer! But ESXi is Free. That said I will likely need some Workstation Licences in the coming months so I may touch base with you on that at some point.

Just as a further update to this thread.

My VSwitch is configured to run at Full Gigabit, MTU Set at 9000. But I am unable to get more than 100Mbit out of the VMs, see below.

post-180771-0-06510000-1335431460.png

ideas?

As you can also see, the individual NICs are set to Gigabit speeds also.

post-180771-0-92438700-1335431593.png

Why do you have your mtu at 9000? Do you have jumbo frames setup on your nics? Does you physical switch support jumbo?

BTW - what is producing that stats page? Showing your disk io and network and memory?

Your graph is terrible why is it all over the place? See mine that is from the VM, and that copy dialog is from my workstation. Also notice my VM nic is showing connected at 10GB, not just 1 ;) I never changed the mtu from default 1500 -- there is NO reason too. Does every device on your network have a 9000 mtu? If not your switch is doing a **** load of work.

From a VM transferring a file to the host ESXi server via SCP I get about 2MB/s... I'm not even kidding, it's abismal.

From one VM host to another on a private internal 'network' I get about 18MB/s.

That's on a dual quare core 8GB server with 2 VMs

SK[' timestamp=1335438001' post='594825411]

I get the same problem, to be honest I haven't looked into it yet, would be interested if you find a fix. it was doing it over iSCSI from a Windows 7 to FreeNAS VM for me.

Keep an eye on this thread then.

I changed up my MTU to 9000 to see if that helped increase the speed, and it did, by 3MB/s. So I've lowered it back down.

How on earth did you get a 10Gbit to show up in ESXi?

Regarding the Graph. Thats VMWares Client for the iPad, the graphs were all over the place until I ripped out that dodgy hard drive, now they're holding stable with no issues.

From a VM transferring a file to the host ESXi server via SCP I get about 2MB/s... I'm not even kidding, it's abismal.

Yeah, transferring directly to ESXi gives me horrid performance too, took about 3 hours to transfer my Server 2008 r2 image over the Console, and about an hour and a half using SFTP.

SK[' timestamp=1335438801' post='594825437]

I know when I tried to set my box to 9000 it said the nic didnt support it.

My entire network supports 9000, I just don't use it normally, this was the one case where I did.

10GB is autoneg with driver for vmxnet3

here

yeah putting files on the datastore directly blows chunks.. I found a lot of threads about ftp server on the older 4.1 esxi that helped, but have not found good thread about putting ftp on esxi 5 yet.

But really only files you have to put there are iso for your installs and patches/upgrades to esxi -- so not too worried about slow speed uploading files to the datastore - not something have to do very often.

It would be supported by anything that you can install the tools too - this has the drivers for it. I had them running on my pfsense box (freebsd 8.3) until I ran into a weird issue with connecting to ipsec/l2tp vpn from behind my router.

Freaking strangest thing -- I have to spend some time documenting it so can put in a bug report. But I could just not get a connection, it would just hang - I even turn on my oakley.log in windows to see the details of the ipsec connection, and nothing looked wrong - it just would hang. As soon as I put the nics back to e1000 on my pfsense vm - bam connected right into my work vpn from my phsycial laptop.

Let me grab a large file from vmfs, my transfers are all too and from RDM drives.. I assume yours are from a vmfs disk?

Yeah I decided against using the vmxnet3 drivers on FreeBSD for the time being.

Ok that is pretty bad! This is writing to my vmfs ? of my vm..

post-14624-0-32268800-1335440223.jpg

Now I run my system drives on my vms as thin provisioned.. So I am quite sure its having to expand out the file system as I copy that file. Let me do a copy back after it gets up there, and I can test read speed from it and then writing file when the file system has already been expanded out, etc.

Ok this copy file from vmfs -- not as good as the RDM drive, and it took a while to ramp up see the networking graph. But its workable I guess. But RDM drive is much better ;) Maybe that is your issue. Give the vm raw access to the disk vs a vmfs.

post-14624-0-41445000-1335440585_thumb.j

Well thats not too shaby there.. I deleted that 3gb file I had copied up to the vmfs, so it would of expanded the drive. Then copied up a different iso (backtrack) and 70MBps -- can live with that for sure.

post-14624-0-62670100-1335440785_thumb.j

Well, thats pretty terrible, and the same kinda speeds I've been seeing.

The Server 2003 R2 box I've setup for sabnzbd was choking, but as the file system has been expanded it's got better.

The Problem comes in as

Incomplete Downloads go to a eager zeroed VMFS

Once downloaded they expand on this VMFS

then move to a Downloads_Complete folder located on a N36L with a dedicated Windows Server 2008 R2 OS

Finally, Sickbeard picks up the file and moves this to a Media Folder after doing some processing on the files.

Annoyingly, I can download a 300MB file faster than I can move it across my network in some instances.

Ok I did copy back from that vmfs, and its rocking.. I even rebooted my workstation to make sure nothing was cached since I had just copied up that iso of backtrack, etc..

post-14624-0-15947300-1335442094.jpg

Can you do a simple iperf test to your vm.. is the bottle neck network or disk??

So as you can see, I see between 750 and 800Mbps with iperf to my vm from my workstation. What do you get?

post-14624-0-09116700-1335442159_thumb.j

Just simple math of 750/8 tells me I should at max there be able to copy at 93MBps -- i am seeing 70 to 80.. So works out pretty well. And when I use that nastester I do believe its close to 90 even.

    • Why Delta Chat is the best decentralized messenger you have probably never tried by Paul Hill There is no shortage of messaging apps out there; we have WhatsApp, Messenger, and Telegram, just to name a few. While Meta has taken steps to incorporate encryption into Messenger and WhatsApp, they still leave a lot to be desired. If you are in the market for a messaging app that promotes security, privacy, and optional anonymity, you'll want to read what I have to say about Delta Chat. For those not familiar with Delta Chat, rather than relying on centralized servers as you do with Facebook Messenger, it relies on email. Essentially, it is a chat interface that feels like a messaging app, but secretly in the background, it is firing off emails. In the past, you used to have to sign in with your email account. When you sent messages to people, it would just be sending encrypted messages to their inbox, which their Delta Chat client would decrypt. When I first learned about Delta Chat, it required users to sign in with an email account, but I was pleasantly surprised upon trying it in 2026 that this is no longer a requirement, or the preferred method was to use the app. Recently, I’ve tried UAD-ng on my old Nokia 3.4 to disable most of the Google apps because the bootloader is locked, and this is the next best option. While finding replacement apps in F-Droid, I came across Delta Chat again, and it has undergone quite a big change since I last used it, with its new chatmail relays, which no longer require you to sign in to your own email account, providing anonymity, and they offer greater security. Android and Desktop Delta Chat apps. Not only does it run on my de-googled phone, but it also works on desktop computers and iOS, making it truly ubiquitous. For me, Delta Chat is a wonderful alternative messenger because it gives you more control. It supports switching between different profiles, which you can set up super quickly; you don’t register a username, you don’t register a password. The only thing you do have is a random string email address on a chatmail relay (which you don’t have to memorize). To maintain access to your profile, you just need to add a second device to your account via QR code or make a backup of your account, which you can restore later. Fail to do these, your account is gone - as it should be if you don’t want to leave accounts that could get hacked later on. My decision to block Google stuff on my Nokia was done for practical reasons; the device sucked when it launched, and it sucks even more now. The nice thing about F-Droid and the apps within is that they’re usually lightweight, free of bloat, and work well on that device. What was inconvenient for me was that it was hard to send messages from that device, say if I wanted to copy a code over to my main phone or send family members a link from that device. That’s when I decided to look at the available chat apps and saw Delta Chat. Another nice thing about Delta Chat is its notifications. Some messaging apps rely on Google’s ecosystem for notification transport on Android; however, with Delta Chat, it can use Google’s solutions if you have Play Services or MicroG installed. Otherwise, it is able to keep a background connection to the chatmail relay server so that you can get notified when you receive a message. As free software, the code of Delta Chat is open for all who want to take it and build upon it. In the future, if the developers of Delta Chat make a catastrophically bad decision and take the app in an undesirable direction, users can take the code and fork the project. This contrasts with closed-source apps from corporations that can take their products in any direction they like. By relying on free software instead of closed-source programs, you actually control your computing. I’ve spoken at length about how running this type of software is like owning your own home rather than renting it. The same applies here; if you use Delta Chat, you don’t need to worry about it going away in the future. Whether it is Telegram, WhatsApp, or Messenger, you are required to register a username and password to use these services. A major flaw in this design is that anyone can try various passwords and potentially break into your account with your complete chat history intact. Sure, there is encryption in Messenger, where you need a second PIN and two-factor authentication in Telegram, but breaches happen all the time. Unlike before, when you used to sign in to your email account to send and receive messages, the primary way to do it now is to create an account on a chatmail relay. The resulting email address is a random string followed by the name of the relay you pick. This means you can start and begin adding contacts Without a username and password, you either need to ensure you have a backup or at least one device running your Delta Chat profile. The primary way to log in on another device is to go to the settings and add a second device. Then, you’ll just scan a QR code with your new device, and it’ll log in to your account and sync all your chat history and contacts. To end users, Delta Chat just looks like any instant messenger; however, it is really sending your messages as encrypted emails to your contact. This is pretty cool from a censorship perspective, as it makes the service more difficult to block. Previously, the main way to use the app was by logging in with email, but nowadays, it’s recommended that you use chatmail relays. Chatmail relays temporarily hold messages in case your device is offline. They are cheap, simple servers that don’t store data as group states. Other information, like your name and avatar, only exists on your device and the devices of those you share your contact information with. The relays are also decentralized and operated by various groups and individuals. It is even possible to set up your own chatmail relay, but most people will want to use one hosted elsewhere. To keep your messages secure, Delta Chat uses a secure subset of the OpenPGP standard that gives you automatic end-to-end encryption. It also uses Secure-Join to exchange encryption setup information through QR-code scanning or invite links. Autocrypt is also used to automatically establish end-to-end encryption between contacts and all members of group chat, but sometime this year Autocrypt v2 will be rolled out, bringing post-quantum resistant encryption and forward secrecy. The Delta Chat FAQ is an interesting read that explains many more details about the app. Credit: Pexels Delta Chat is unique among messaging apps because it is built on email, a technology that’s decades old and isn’t going anywhere soon. What’s more is that email is not centralized either, so it’s far more difficult for any authoritarian regime to disrupt the Delta Chat app. I haven’t spoken too much about features yet, so I will do that now. Delta Chat allows you to do one-on-one chats, group chats, and create channels. It also supports file sharing and making audio and video calls when chatting one-to-one, but it’s not available for group chats right now. At the time of writing, the calling functionality is disabled and can be enabled in Settings > Advanced > Debug Calls. I have used the video calling feature, and the quality is excellent. It works over WebRTC, another open standard. The app also lets you send voice notes, enables disappearing messages, and has its own app ecosystem. I did try playing chess one time there, but it was a bit spotty; though, we did manage to complete the game with a victory for me. To add people to Delta Chat, you can either give them your Delta Chat link or your QR code to scan. These are the only ways to add users, so you won't have any spam bots bothering you. If the people you want to chat with don't have the app yet, just send them your link, and it will take them to a webpage where they can install the app and then add you. It's really quick for them to install it and get started, which is nice. Credit: Microsoft. The Majorana 2 quantum chip unveiled in 2026. I do not think quantum computers are too far out now, and I do hope that Delta Chat is able to push out Autocrypt v2 sooner, rather than later, so bad actors do not attempt to collect encrypted communications and then decrypt them in the future using quantum computers. By getting people’s messages post-quantum-safe now, users won’t have to worry when quantum computers start cracking legacy encryption. Overall, I would recommend this app to people who are already past WhatsApp and Messenger and have perhaps begun using apps like Telegram or Session. It shares a lot of characteristics with these apps and goes a lot further than Telegram in terms of security. By being based on email, it is also resistant to censorship, and the lack of a username and password makes you anonymous (if you want to be) and safe from brute force password cracking attempts. Let me know in the comments if you’ve tried Delta Chat recently. Do you think it's a good bulwark against governments that are tightening their grip on the internet?
