Experiments with different Intel Processors in a HPE ProLiant Microserver Gen8 – Part 2

Thursday, April 28th, 2016

So, I’ve managed to get my hands on some new Intel Processors to test in the HPE ProLiant Microserver Gen8, now supported and the microcode has been updated in the latest BIOS as reported in this blog here, I’ve got two of the following

Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor packaged in Costa Rica and Malaysia. I’ve been to Costa Rica here, didn’t notice any Intel fabs, whilst I was there!

Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor - Costa Rica

Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor - Malaysia

Intel® Celeron® Processor G1610T (2M Cache, 2.30 GHz)

collection of procs for Gen8

The HPE ProLiant Microserver can be purchased with an Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor see here , but oddly it’s supplied with NON-ECC RAM, and here is the weirdness, if you inspect the “Intel Ark” for the processor it’s displayed as not supporting ECC RAM.

WOT NO ECC support ?

WOT NO ECC support ?

Is this an Intel conspiracy, the Intel ARK used to show it as supported, but later it has now been changed, to No. Is this to encourage people to purchase a Xeon which supports ECC, or did Intel find a support issue?

Anyway proof of the pudding the Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor supports ECC RAM, and is a very inexpensive upgrade for a HPE ProLiant Microserver Gen8 from the stock Intel® Celeron® G1610T (2.3Hz/2-core/2MB/35W) Processor. So Andy says, upgrade your Gen8 today with a Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor! what are you waiting for!

It works! and a very cost effective upgrade with 6784.63 bogomips!!! compared to 4589.69 which the G1610T has!

You may have concerns that the Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor has a TDP of 55 or 65 watts, and the stock heatsink in the HPE ProLiant Microserver Gen8 for the Intel® Celeron® G1610T (2.3Hz/2-core/2MB/35W) Processor is 35 watt. If you purchase a HPE ProLiant Microserver Gen8 with a Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor it’s supplied with an uprated and different 65 watt heatsink.

so we will test that to in my next blog, and see if I can melt a HPE ProLiant Microserver Gen8!

I’m now testing which performs best the Costa Rica or Malaysia package ? Blog soon!

Experiments with different Intel Processors in a HPE ProLiant Microserver Gen8 – Part 1

Wednesday, April 27th, 2016

I’ve recently managed to get hold of a HPE ProLiant Microserver Gen8 server, to test and maybe eventually replace my aging HP ProLiant Microserver N36L’s see here. I cannot believe it’s been almost 5 years since, I purchased my cluster of N36L to run VMware vSphere.

The HPE ProLiant Microserver Gen8 has been around for some time now, and represents good value for money, and is closer specification to the original ProLiant range than the previous Microserver offerings, e.g. iLo4 support, dual network interfaces, ECC ram support, and a socketed Intel 1155 processor socket.

Four different processor models of the HPE ProLiant Microserver Gen8 are available direct from HP resellers. See the quick specs here.

Intel® Celeron® G1610T (2.3Hz/2-core/2MB/35W) Processor

Stock G1610T

Intel® Pentium® G2020T (2.5GHz/2-core/3MB/35W) Processor

Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor

Intel Core i3-3240

Intel Core i3-3240

Intel® Xeon® E3-1220Lv2 (2.3GHz/2-core/3MB/17W) Processor

Xeon E3-1220LV2

Xeon E3-1220LV2

The first two models are commonly available, the Xeon version is not as common, and the Intel® Core™ i3-3240 (3.4GHz/2-core/3MB/65W) Processor version seems a new addition, after noticing this in a recent BIOS update – which states Added support for Intel i3-2130 and i3-3240 processors.

It’s often much cheaper to purchase and fit an aftermarket Intel CPU, than purchasing the HPE model of the Gen8. Let the testing commence…

Breaking Bad and Better Call Saul

Sunday, April 24th, 2016

A bit late to the party, a close friend and my brother suggested I watch Breaking Bad, and then Better Call Saul, so I’ve just finished watching all 5 Seasons of Breaking Bad, and 2 Seasons of Better Call Saul, that’s approximately 3 days of Box Set viewing!

And coincidently, Better Caul Saul, Season 2 has just aired and finished!

RARE – Intel Xeon E3-1220LV2 Processor for my HP ProLiant MicroServer Gen8

Tuesday, April 12th, 2016

Here is the replacement processor for my HP ProLiant MicroServer Gen8. It has taken me a while to track this one down. It has a TDP of only 17 watts, compared to the stock Intel Celeron G1610T, which has a TDP of 35 watts.

These are like rocking horse dodo…

It’s an Intel Xeon E3-1220L V2, it’s a low power, 17 watt, 2 Core, 4 Thread Xeon with Intel VT-d.

I’m waiting for my thermal compound, before I install it.

Synology NAS and SSD Cache Part III – Is cache better for VMware vSphere (ESXi)? Confusing results!

Monday, April 11th, 2016

So in today’s, crude and experimental research I thought I would connect all our VMware vSphere Hypervisors (ESXi 5.5 build 1892794) to a NFS datastore presented to the ESXi Hosts from a Synology NAS, and we’ll try the following tests

I deployed a small Windows 7 template, onto the NFS datastore as follows

  • No Cache Enabled – 3 minutes 27 seconds to deploy
  • Read and Write Cache Enabled – 2 minutes and 40 seconds to deploy.

Time for some more testing – The template deployed to the datastore was converted to a virtual machine, and the following tests were performed using CrystalDiskMark 5.1.2 in the virtual machine.

NFS Exported volume No SSD Cache on the Synology NAS.

NFS Exported volume Read and Write SSD Cache on the Synology NAS.

NFS Exported volume Read only SSD Cache on the Synology NAS.

Some a bunch of very confusing results! And every time I test the results are similar.

Synology NAS and SSD Cache Part II – Is cache better for Plex Media Server ?

Sunday, April 10th, 2016

In my recent article comparing the performance of the addition of a Read and Write SSD Cache to a volume on a Synology NAS, I started to look in detail at whether this cache benefits any other services on a Synology NAS running DSM 5.2.

In this experiment I’m looking at the Plex Media Server, and I’ve setup two identical Synology NAS, running DSM 5.2 Build 5644 Update 5, both with Plex Media Server, both are streaming the same 1080P Blue Ray movie to the same Plex client via WiFi, at the same time. The first NAS has no cache, the second NAS has 120GB of read and write cache, and these are the results.

The second NAS with the read and write cache enabled shows, lower Disk Utilization 1% compared to 5%.

Again you can see here, 6% (no cache), 1% (cache)

The same stats from both NAS, No cache and cache enabled, what is interesting is the CPU load results are lower on the cache enabled version!

Synology NAS and SSD Cache

Saturday, April 9th, 2016

I’ve been recently experimenting with SSDs (solid state disks), to accelerate my spinning rust in my Synology NAS.

Recently in DSM, a new SSD cache option is available, which allows you to create a read or write cache with 1 or 2 SSD devices respectively.

Here are some results, which I’ve graphed


In my very quick and crude tests, I could see an improvement in Writing to the NAS, which doubles in performance. Read speed is very similar, and the cache was “warmed-up” before testing.

And here’s a video of the new Synology SSD Cache Read Hit Rate graphic, which looks a little graphic equalizer, from the 70-80s, so I’ve dropped a music track in the background! I thought it only right to over-flange (distort!) the track, so you may want to turn down your volume!

Spot the difference between these two Brother P-Touch tapes

Wednesday, April 6th, 2016

Spot the difference between these two White on Green Glossy Laminuated TZ-735 Brother P-Touch tapes?

The one on the right costs £14.00, and the one on the left costs £3.85, both including delivery.

What I had a chuckle about is the compatible tape is correct stating it’s 0.47 inch, and not 1/2 inch, if you work out what 12mm is in inches!

Both function correctly in the two Brother P-Touch label printers I have tested, but the one on the left is marked as P-Touch compatible, it’s not a genuine Brother product, and manufactured in China. Readily available from eBay, or other online stockists!

I was going to throw my P-Touch label printer in the bin, because the cost of replacement tapes was so expensive!

I’ve just taken delivery, of four of these cartridges, at approx. £10 – 6mm,9mm,12mm and all work as expected, this would have cost four times this amount for the Brother original parts! – Direct from China, including packaging and posting, arrived well packed, signed for delivery and within 7 days excluding weekend.

I’m not sure what is going to happen, when the China bubble bursts!
