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.
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
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.
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 0.9.15.2.1663, 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!
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!
This is what they look like inside, if you’ve ever wondered!
I’ve had a stack of many SCSI, IDE, SATA, SAS disks on the shelves for many years, ranging in sizes from 40MB, 9GB, 36GB, 72GB, 146GB, 500GB, 1TB and 2TB, time to test them all. Out of 50 SATA drives, 6 had failed just because they had been sitting on the shelf doing nothing.
I’ll strip them down, and use the spinning platters, as bird scarcers for my allotment, to keep the pigeons at bay! It takes me 30 seconds to strip them down and remote the platters, and then I’ll shuffle the platters, and string them on my allotment, that’s stops my data being recovered!
This SATA hard drive, the heads have crashed into the platters, and started to score them, see here
This is what a hard drive should look like
Here’s a single platter

here’s a short video of the inside of a hard drive, with the cover removed, with crashed heads.

And one pill makes you small,
And the ones that mother gives you,
Don’t do anything at all,
Go Ask Alice
When she’s 10 feet tall…….”
This was an early Christmas (2015) present, and more gadge for the office. But it does have a serious side, because I decided there is far too much paper in my life, and from late 2015 I’ve gone paperless. So it’s also my New Year’s Resolution for 2016.
No paper!
The ScanSnap is fantastic, wireless scanning via WiFi to laptop, Android Phone, iPad, software is brilliant, one of the best software installs and setups, I’ve ever performed with any hardware! – Well done Fujitsu! – It’s a good job, that not all hardware and software is like that, I would be out of a job! Drop all my paper into the top of the scanner, Hit the blue button, or do it remote from my PC, and I end up with a bunch of searchable PDF files.
Local Storage is cheap as chips, Cloud Storage is even cheaper, it’s far quicker for me to pull documents from my “DocStore” than try and find anything in a filing cabinet, if I need a hardcopy, I just print it out. I can also easily give access to my “DocStore” securely via the Internet to Lindsey also, so she can look at all my documents.
So all my documents, are now scanned to an Adobe PDF document, OCR recognition is performed on this document, before it’s saved to create a Searchable Adobe PDF document, this is then saved to a folder structure on my PC, e.g. 2016 > Finance > Credit Cards.
The “DocStore” is then mirrored to two Synology NASes using Cloud Station and these are backed up to Amazon S3 Cloud, and I also use Tresorit secure Cloud Storage.
At present I’ve got approximately 1000 pages in my “DocStore”, which is about 1.4GB, and when I’m finished it closes up nicely.
I’ve wanted to publish/write articles for Andysworld! For many years, directly from Microsoft Word (offline), and then hit a button to publish. I never noticed that Microsoft Word has this incorporated!

Simply! Done!
Last week on Friday 6th February 2016, the latest list of vExperts for 2016, was posted here.
So let the fun begin…
