For Sale – Super server bundle: 14 core E5-2695 v3, ASRock Extreme 6 X99 mobo, 80GB DDR4 ECC RAM

I have a super powerful CPU, mobo and RAM bundle here that would make a great home server, I have used it as an unRAID server for about 18 months or so but am downsizing.

I have used this rig for running unRAID with dockers and VMs. When running VMs you can do GPU pass-through and I’ve had really powerful multi-core Mac Pro desktop running as well as a gaming VM with a GTX 1060 passed through. It’s an absolute beast. Great for running multiple VMs as a home lab.

ASRock X99 Extreme 6 ATX motherboard
Intel Xeon E5-2695 14 core/28 thread CPU
80GB !! (5 x 16GB, 4 Crucial and 1 SKHynix) of ECC DDR4 2133 memory

Motherboard specs:-
On-board dual LAN
Supports up to 128GB RAM
Ultra M.2 slot
8 RAM Slots

Intel Xeon E5-2695 v3 14 core/28 thread CPU. This is a late stepping engineering sample indistinguishable from retail. The v3 Xeons had a “bug” from Intel where using patched Microcode you can bypass the usual turbo boost restrictions to have all the cores running at single core boost speeds. In this case you can have all 14 cores running at 3.3GHz. The ASRock motherboard already has the patched BIOS in place so all you have to do it plug and play.

If you wish to go back to stock, simply update the motherboard with the latest BIOS from ASRock from within the BIOS itself. I will supply the patched BIOS anyway so you can always go back. As long as you have a decent CPU cooler then it is fine. even at full tilt my CPU never went over 60 deg. Although I did this for interest sake, my server sat idling 99% of the time anyway so a bit of a waste for me

Here is the Anandtech thread where it was all discovered and people built the mods:-

Page 3 – What controls Turbo Core in Xeons?

Also here is an explanation of all core vs single core boosts :
Actual CPU Speeds – What You See Is Not Always What You Get

Looking at current prices on ebay especially RAM which is crazy right now, this lot is worth about £800 or so, so I think this is a good price.

Price and currency: £550
Delivery: Delivery cost is included within my country
Payment method: BT or PPG

For Sale – iMac Pro 3.2GHz 8-core Intel Xeon W processor 64 GB Ram & 2TB Hard drive

Hi,

Before I put this on the bay I thought I would try here first as prefer to sell to a forum member whenever possible.

I bought this last week in an auction, it’s brand new but I have taken it out of the box and checked it out as I had planned to use on a job that has now altered and it’s no longer needed. The mouse and keyboard are still in packaging and completely unused.

Specs:

IMac Pro

  • 3.2GHz 8-core Intel Xeon W processor, Turbo Boost up to 4.2GHz
  • 64GB 2666MHz DDR4 ECC memory
  • Radeon Pro Vega 56 with 8GB of HBM2 memory
  • 2TB SSD storage
  • Magic Mouse 2 – Space Grey
  • Magic Keyboard with Numeric Keypad – British – Space Grey

It’s obviously still in warranty plus it has Apple Care + so it’s covered for three years as from a July 1st 2019.

To buy new from Apple it would cost £5799, I paid £4600 last week but looking for £3800 ono for a quick sale. Just to reiterate this item was brand new unopened last week and has only been opened to check and prepare for a job that then cancelled.

You can see from my feedback I have an excellent record plus I have been a member on here since 2001.

Collection would be best (I am in West Sussex) but could arrange delivery if that is only option.

Happy to answer any questions etc. Will give it a day or two and then advertise elsewhere. can upload photos tomorrow.

Cisco’s acquisition of Acacia bolsters service provider offerings

Cisco plans to acquire Acacia Communications for $2.6 billion, a move that would make Cisco a direct supplier of packet-optical transport systems for carrier networks and organizations that connect data centers across hundreds of miles.

Cisco announced the pending purchase on Tuesday in a joint statement with Acacia, based in Maynard, Mass. The companies expect to close the Cisco acquisition in the first half of next year.

Cisco offers Acacia’s packet-optical transport systems (P-OTS) with networking gear it sells today to carriers, cloud service providers and the largest enterprises. Cisco rivals Juniper Networks and Huawei are also Acacia customers, and analysts expect them to eventually turn to other P-OTS suppliers, such as Ciena, Inphi and Nokia.

“If I’m a Juniper or a Huawei, why would I buy from Cisco?” said Rajesh Ghai, an analyst at IDC.

Bill Gartner, general manager of Cisco's optical systems groupBill Gartner

Nevertheless, Acacia customers can expect from Cisco the same level of support that they receive today and equal access to products, said Bill Gartner, general manager of the vendor’s optical systems group.

“If we’re going to make this successful, we have to make sure that we’re providing the technology to third parties that they want to consume at the time they want to consume it and at the right performance and price point,” Gartner said. “I don’t think we could make this successful more broadly if we give Cisco preference on any of those parameters.”

Reasoning behind Cisco acquisition

Cisco has agreed to acquire Acacia because the company’s optical interconnect technology will let Cisco help customers design networks that can keep pace with the projected increase in data traffic. Cisco has predicted that annual global IP traffic will increase from 1.5 zettabytes in 2017 to 4.8 zettabytes by 2022. Contributors to the traffic surge include internet growth, video content delivery and emerging next-generation wireless technology to support more demanding business applications.

Today, Cisco’s proprietary optical transport technology ends in the data center, where analysts expect port speeds of 100 Gbps and 400 Gbps to become commonplace over the next couple of years. To meet that emerging demand, Cisco this year completed the $660 million acquisition of silicon photonics company Luxtera.

With Acacia, Cisco will also own the optical technology for service providers that need high-speed connections for metropolitan area networks or data centers as far as 1,500 miles apart.

“Our optics business today is primarily addressing what’s happening inside the data center — short-reach optics,” Gartner said during a conference call with financial analysts. “We don’t have a portfolio today that addresses what happens outside the data center for pluggables.”

Acacia’s portfolio includes pluggables, which are optical modular transceivers that vendors can sell as a plugin for a router or switch. The pluggable architecture, which is in its infancy, promises to simplify upgrading and repairing transceivers in networking gear.

John Burke, an analyst at Nemertes Research, based in Mokena, Ill., said Acacia could help Cisco “stay dominant in large data center markets long term,” while also providing some technical advantages over Arista, Juniper and Huawei.

“I suspect it will also give a boost to some smaller optical companies and trigger at least one more acquisition — perhaps by Arista,” Burke said.

Try these PowerShell networking commands to stay connected

While it would be nice if they did, servers don’t magically stay online on their own.

Servers go offline for a lot of reasons; it’s your job to find a way to determine network connectivity to these servers quickly and easily. You can use PowerShell networking commands, such as the Test-Connection and Test-NetConnection cmdlets to help.

The problem with ping

For quite some time, system administrators used ping to test network connectivity. This little utility sends an Internet Control Message Protocol message request to an endpoint and listens for an ICMP reply.

ping test
The ping utility runs a fairly simple test to check for a response from a host.

Because ping only tests ICMP, this limits its effectiveness to fully test a connection. Another caveat: The Windows firewall blocks ICMP requests by default. If the ICMP request doesn’t reach the server in question, you’ll get a false negative which makes ping results irrelevant.

The Test-Connection cmdlet offers a deeper look

We need a better way to test server network connectivity, so let’s use PowerShell instead of ping. The Test-Connection cmdlet also sends ICMP packets but it uses Windows Management Instrumentation which gives us more granular results. While ping returns text-based output, the Test-Connection cmdlet returns a Win32_PingStatus object which contains a lot of useful information.

The Test-Connection command has a few different parameters you can use to tailor your query to your liking, such as changing the buffer size and defining the number of seconds between the pings. The output is the same but the request is a little different.

Test-Connection www.google.com -Count 2 -BufferSize 128 -Delay 3

You can use Test-Connection to check on remote computers and ping a remote computer as well, provided you have access to those machines. The command below connects to the SRV1 and SRV2 computers and sends ICMP requests from those computers to www.google.com:

Test-Connection -Source 'SRV2', 'SRV1' -ComputerName 'www.google.com'

Source Destination IPV4Address IPV6Address
Bytes Time(ms)

------ ----------- ----------- -----------
----- --------

SRV2 google.com 172.217.7.174
32 5

SRV2 google.com 172.217.7.174
32 5

SRV2 google.com 172.217.7.174
32 6

SRV2 google.com 172.217.7.174
32 5

SRV1 google.com 172.217.7.174
32 5

SRV1 google.com 172.217.7.174
32 5

SRV1 google.com 172.217.7.174
32 5

SRV1 google.com 172.217.7.174
32 5

If the output is too verbose, and you just want a simple result, use the Quiet parameter.

Test-Connection -ComputerName google.com -Quiet
True

For more advanced network checks, try the Test-NetConnection cmdlet

If simple ICMP requests aren’t enough to test network connectivity, PowerShell also provides the Test-NetConnection cmdlet. This cmdlet is the successor to Test-Connection and goes beyond ICMP to check network connectivity.

For basic use, Test-NetConnection just needs a value for the ComputerName parameter and will mimic Test-Connection‘s behavior.

Test-NetConnection -ComputerName www.google.com

ComputerName : www.google.com
RemoteAddress : 172.217.9.68
InterfaceAlias : Ethernet 2
SourceAddress : X.X.X.X
PingSucceeded : True
PingReplyDetails (RTT) : 34 ms

Test-NetConnection has advanced capabilities and can test for open ports. The example below will check to see if port 80 is open:

Test-NetConnection -ComputerName www.google.com -Port 80

ComputerName : google.com
RemoteAddress : 172.217.5.238
RemotePort : 80
InterfaceAlias : Ethernet 2
SourceAddress : X.X.X.X
TcpTestSucceeded : True

The boolean TcpTestSucceeded returns True to indicate port 80 is open.

We can also use the TraceRoute parameter with the Test-NetConnection cmdlet to check the progress of packets to the destination address.

Test-NetConnection -ComputerName google.com -TraceRoute

ComputerName : google.com
RemoteAddress : 172.217.5.238
InterfaceAlias : Ethernet 2
SourceAddress : X.X.X.X
PingSucceeded : True
PingReplyDetails (RTT) : 44 ms
TraceRoute : 192.168.86.1
192.168.0.1
142.254.146.117
74.128.4.113
65.29.30.36
65.189.140.166
66.109.6.66
66.109.6.30
107.14.17.204
216.6.87.149
72.14.198.28
108.170.240.97
216.239.54.125
172.217.5.238

If you dig into the help for the Test-NetConnection cmdlet, you’ll find it has quite a few parameters to test many different situations.

For Sale – Internal & External Hard Drives

Can you please state what health check you would like me to perform (if you are making an offer based on a health check)?

The drives have all been used in a HTPC that didn’t see much use at all (on once or twice per week for a movie). The Samsung drives are probably around 3 years old and the Seagate drives between 1 and 2 years.

The 2 external drives are around 12 months old. but it is best to assume that no warranty is provided (and you may be pleasantly surprised if you check the serial number).
