I've been working on a plan to upgrade my gaming rig lately, especially since I had a 4790K come available with the upgrade of the FreeNAS box. For Christmas, I got a pair of Gigabyte R9-390X's to upgrade my dual HD7970's. I've been running 32GB of RAM in my 4770K box for quite a while now, so there was nowhere to go from there. The plan was to replace the Gigabyte Z87X-OC and i7-4770K with the ASRock Z97 Extreme6 and i7-4790K from the FreeNAS box. The Z97 board has a PCI 3.0 x4 M.2 slot on it, so I wanted to get the speed increase from using it in addition to everything else. But, here's the problem...
The LGA1150 processors, which means ALL the Haswell processors not considered "Enthusiast / High End"; so the Core i3, i5, and i7s with a 4XXX model number or a G3XXX model number; only have 16 PCIe lanes. The Core i7-5820K (6 core) has 28 lanes and the 5930K (6 core) and 5960X (8 core) both have 40 lanes. Now, let's do some math on what I wanted to go into that computer:
- Two R9-390x's - 32 Lanes
- M.2 4x - 4 Lanes
- Thunderbolt 2 AIC - 4 lanes
Well, I'm no mathematician, but I know 40 lanes when I see them. That only left me one option if I wanted to stick with Haswell, and that's to go with the 5930K. The 5960X is still a $1000 processor and I just wasn't going to drop that kind of coin on a CPU. So, today I went ahead and placed the order and here's the new specs for the new gaming rig:
- Intel Core i7-5930K CPU
- Corsair H110i GTX Liquid CPU Cooler
- ASRock X99 Extreme6/3.1 Motherboard
- 32GB Corsair Dominator Platinum DDR4-2666 (4 x 8GB)
- 2x Gigabyte R9-390X 8GB
- ASRock Thunderbolt 2 AIC
- Samsung 950 PRO 512 GB M.2 4x SSD
- Samsung 850 EVO 1TB SATA6 SSD
- Corsair Obsidian 750D Full Tower Chassis
- Corsair AX1200i PSU
- Corsair Professional Blue Individually Sleeved PSU cables
- 5x Corsair SP140 Blue LED Case Fans (2 front, 2 on the radiator, 1 rear)
- Corsair Link Commander Mini
- 2x Corsair RGB Light kit
No spinning platters in this baby! We're going ALL SSD. Spinning platters are for the NAS. The motherboard has dual gigabit NICs, and my network devices all support link aggregation, so I'll be able to get 2 gigabit network access to the NAS, and that should be more than enough for pulling documents or anything else I need off of it. All this will be displayed on my current triple AOC i2769Vm 27" monitors, which give me nearly 6 linear feet of monitor space. Yes, they are only 1080, but I'm not quite ready to dump out the money for three 27" 4K monitors and they don't make ultra-wide curved monitors big enough for me yet.
Today's order was for the CPU, motherboard, and RAM. Everything else is already here. I'm hoping that everything will be here by the end of the week and I'll be able to finish the build this weekend, so I can finish working on the FreeNAS / Plex Automation series.
Here's a sneak peek of what it'll look like. I was mounting the lights and fans in the case last night, and since the X99 Extreme6 and the Z97 Extreme6 look nearly identical, it'll give you an idea of what we'll be dealing with when it's all said and done.
I think that, in this day and age, everyone should have a NAS at their house. For those of you that don't know what I'm talking about, NAS stands for 'Network Attached Storage'. A NAS is handy for storing all sorts of things, primarily backups of your computers and your media. In my case, I have a lot of movies and TV shows for my various media players. I also have a ton of photos and videos from over the years, as well as from my drones. Having a large NAS means that I don't have delete anything. My NAS also acts as a server for various other things that I'll get into in another post.
For your NAS to be effective, it needs to have lots of space and have enough room to expand. You also need to have an effective operating system running the NAS. For this build, I'm going to use FreeNAS. I had been planning to build this thing for a while, but didn't get around to finally getting everything setup and running until July 31, 2015. Since then it's been running pretty stable, but I used an Intel G3220 and 8GB of RAM when I first put it together and I've outgrown that processor and RAM, so it's time for an upgrade. Here's the hardware list of everything that's going into the machine:
- Intel Core i7-4790K CPU
- ASRock Z97 EXTREME6 ATX LGA1150 Motherboard
- G.Skill Ripjaws X Series 32GB (4 x 8GB) DDR3-1600 Memory
- 6x WD Red 3TB 3.5" 5400RPM HDD
- Rosewill RSV-L4412 - 4U Rackmount Server Chassis, 12 SATA / SAS Hot-swap Drives
- EVGA SuperNOVA 1000G2 1000W 80+ Gold Certified Fully-Modular ATX Power Supply
The only thing that's carrying over from the previous build are the 6 WD Red 3TB hard drives and the actual FreeNAS install. I was going to just upgrade the CPU and the RAM, but some pins got bent on the ASUS Z87-A motherboard I had, so it needed to get upgraded too. I also figured that while I was at it, I'd put it in a nice rackmount chassis too.
The build went rather smooth. I pulled the hardware out of the old mid-tower case and moved it into the rackmount chassis. I had originally planned on using some M.2 SSDs for boot drives, but ran into some issues. First, the drives I bought weren't compatible with the Ultra M.2 slot on the motherboard. Secondly, the other M.2 slot ate two of my SATA ports on the motherboard. Because I didn't bother to read the manual, it took me quite a while to figure out why those two drives weren't being seen by the BIOS. Ultimately, I got everything put together and all 6 drives were being recognized. FreeNAS booted right up without any issues. I'll probably pick up an Ultra M.2 SSD in the future to use as L2ARC since it's so freaking FAST.
More info will be posted soon on how I'm going to automate my media collection and sharing.
Just had an interesting problem with a customer that seems a bit obscure, so I figured I would write it down to help someone else. All of the other solutions to this issue focus solely on there being a problem on the Windows side, which may not necessarily be the case.
Situation: customer is setting up a Windows 2008 R2 server in a VMware cluster, on a VLAN that is sitting behind a firewall. The firewall is is the gateway for the VLAN (say 192.168.34.1). When configuring the network interface on the server, picking ANY IP address in the 192.168.34.0/24 network results in the error message “Windows had detected an IP address conflict”. This happens even if there are no other devices on the VLAN aside from the firewall.
The issue? There was a static (identity) NAT entry in the Cisco ASA firewall for 192.168.34.0/24. By default, Cisco firewalls will proxy ARP for NAT entries.
- (8.3(1), 8.3(2), and 8.4(1)) The default behavior for identity NAT has proxy ARP disabled. You cannot configure this setting.
- (8.4(2) and later) The default behavior for identity NAT has proxy ARP enabled, matching other static NAT rules. You can disable proxy ARP if desired.
This is desirable behavior for a firewall on the edge of the network because the upstream router needs to know where to send traffic for NAT’ed hosts. For internal firewalls this can cause issues, especially with 8.4 code where you need to setup identity NAT to exempt devices from NAT.
The solution? Add “no-proxy-arp” to the end of your identity NAT statements:
nat (inside,outside) source static obj_Internal obj_Internal no-proxy-arp route-lookup
The other (less desirable) solution is to disable the ARP-checking functionality in Windows, but this means it won’t be able to detect a legitimate IP conflict. You can do this through a quick registry hack: HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters, create a DWORD named “ArpRetryCount” with a value of “0?.
I recently signed up for the Square service to accept credit cards on my iPhone. They have two different ways of charging fees: 2.75% per transaction when you swipe the card using their reader or 3.5% + %0.15 per transaction if you enter the card number manually. Since I've already written mobile fee calculators for both PayPal and Etsy, I decided to use the same code and make one for Square. All 3 are designed to fit perfectly on an iPhone screen and since they are very lightweight, they run pretty quick. If you use any of these services, these calculators will come in very handy!
I recently got a wild hair up my ass to add a RAID to my desktop. My desktop is a Gateway FX6840-23 and it came with a 1TB drive. I bought an identical drive and thought that I'd put then in RAID 0 for the increased performance, seeing as my Experience Index was only 5.9 due to a slow HDD (all other indexes were in the mid-7's, and the drive is a 7200 RPM unit).
Digging around the BIOS I saw that the SATA controller was using AHCI mode. I cloned my current drive to another 1TB drive I had (yeah, I have 3 -1TB drives, a 500GB, and a 1.5 TB), rebooting into the BIOS and changed it to RAID. After a reboot, I hit ctrl-I and entered the RAID utility. I built the RAID and rebooted. Well, to put it nicely, I got a BSOD. I tried various things for the next 3 hours, including using Windows 7's extended partition utility, doing a complete restore to factory on the extended partition, and everything. After I did the restore, I saw that the HDD performance hadn't changed.
Well, I haven't messed with RAID before on a desktop, so this was a learning experience. After some Google searches, I put the computer back in AHCI mode and booted to the clone. This worked just fine. I went to Gateway's website and downloaded the RAID drivers.
I noticed that the driver was named iaStorV.sys, so I did a search for it and found it already installed in the Windows\System32\Drivers folder. I did a registry search for it and found it in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV. This made me happy!
Some more Googling later and I figured out that if I changed the REG_DWORD from 3 to 0 that it would enable things to work. I rebooted the computer, went back into the BIOS and changed the SATA controller to use RAID, pointed it to boot from the clone, and it booted right up! No BSOD, no hiccups, no nothing!
This should work going from IDE mode as well. I tried to clone the clone to the RAID, but Acronis didn't like that too much, so I'm doing a full backup of the clone (I needed to do it anyway) and I'm going to try to restore it with the Acronis Resuce media. It's already midnight, and this is one of those things that I'm not going to be able to put down until I'm done with it. Oh well, I guess it's time to get back to work! Good luck getting your stuff working!
