Upgrading the HPE Microserver Gen 8 and putting it into service

A year and a half after my original write-up of the Ivy Bridge-based Gen8 Microserver, I’m finally doing a last round of pre-launch updates and documenting the upgrades I made.

You can read the original write-up (as updated to December 2018) here: Warming up the HP Microserver Gen8 and PS1810-8G switch

More links at the end of this post.

Where do we start?

The HPE Microserver Gen8 as I received it had the Intel Pentium G2020T processor, a dual core, dual thread, 2.5 GHz processor with integrated Intel HD Graphics. For an ultra-low-end workgroup or SOHO server, that’s not too bad, and it’s better than the Celeron G1610T option.

Stock processor options for the HP Microserver Gen8

But since we’re not worried about the warranty and do want a bit more power, we looked at the following options for a CPU upgrade.

Xeon Processor CPU speed C/T TDP Integrated graphics? eBay price/link
December 2018
E3-1230 v2 3.30 – 3.70 4/8 69 No 75.00
E3-1260L (v1) 2.40 – 3.30 4/8 45 HD2000 57.00
E3-1265L v2 2.50 – 3.50 4/8 45 HD2500 100.00

Since we didn’t have a use case in mind for this, we went for the E3-1265L v2 processor. CPU speed is reasonable, power is within the envelope for this system’s cooling capacity, and the price didn’t turn out too bad (although it was almost twice as much a year and a half ago).

The system arrived with 16GB of memory, which is the maximum supported with this generation of processor and a two-DIMM-slot motherboard (the CPU will handle 32GB but no more than 8GB per DIMM, and the Memphis Electronics 16GB DDR3 DIMMs require a newer generation of CPU).

The system also shipped with a single 500GB SATA drive and three empty trays for expansion, connected to the onboard B120i storage controller. There’s a low profile slot at the top suitable for an optical drive, or a hard drive carrier. According to the specs, the first two bays are 6gbit SATA and the last two bays are 3gbit SATA. You can add a P222 Smart Controller to provide battery-backed cache and expanded RAID options; these can be had for under $50 on eBay.

I installed a 32GB Micro-SD card for OS boot. Like the previous Microservers, the Gen8 offers an internal USB port, but Gen8 adds a MicroSD slot which may be less likely to snap off during maintenance. If I were running a heavy duty Windows or Linux server on this machine, I’d probably either put an SSD on a PCIe carrier card or use the optical drive SATA connector on the board to mount a boot drive in the optical bay. But for VMware or appliance-type platforms, or for light use Linux, the MicroSD should be enough.

Bringing the Microserver Gen8 up to date

One of the first things I do when building or populating a system is to upgrade any applicable firmware on the system. This could include the lights-out management, the system BIOS itself, drive controllers, optical drives, etc.

This gets complicated with HPE gear, as they decided to restrict all but “critical” BIOS update to customers with active support contracts or warranties. There are dubious workarounds, but it’s more of a pain than for any other mainstream vendor. Luckily (and I say that sadly), some of the critical vulnerabilities around Intel microcode in the past year led to the most recent Microserver Gen8 BIOS being considered critical.

So I gathered the latest BIOS, the ILO 4 firmware for out-of-band management, and the latest firmware for the PS1810-8G switch that this system will be connected to. (Unlike the computer systems, HPE’s networking gear carries a lifetime limited warranty and free access to firmware updates.)

With the switch connected to our upstream POE switch and the Microserver’s three network ports (two gigabit LAN, one ILO) connected to the switch, I upgraded the firmware on all three components and installed CentOS 7 from the latest ISO image via external USB flash drive. Additionally, I got a free 60-day trial license for ILO 4 Advanced from HPE.

One quirk I ran into was with regard to the .NET-based remote console and Chrome browser. In short, it doesn’t work unless you install a plugin to handle the .NET launching. I didn’t want to bother with Java either, so I accessed ILO from Microsoft Edge and used the .NET option from there.

Where do we go from here?

In the near term, I’m planning to install the Aquantia AQN-107 10GBase-T/NBase-T adapter and use it to test a couple of new devices in the home lab. Linux with iPerf or the like should be a good endpoint, and with a Thunderbolt 3-to-NBase-T adapter and an economical NBase-T/10G switch to work with, it should be compact and functional.

Longer term, with the former VMware “$25 server” being converted to EdgeLinux (from the makers of the Antsle servers we wrote about here and here), I will probably have this box serve as my in-home vSphere / ESXi system.

There’s a very small chance that I’ll break down and get the new Gen10 machine, but with as many spare computers as I have in the home lab now, it’s not a high priority.

Looking ahead into 2019 with rsts11

This is becoming somewhat of a tradition… I’ll point you toward a Tom Hollingsworth post and then figure out what I want to look back on a year from now. As long as Tom’s okay with that, I am too.

This year, Tom’s New Year’s post is about content. He seems to think 2019 is the King of Content. I’m not really sure what that means, but seeing as my blogs seem to be alternately seasonal (with most rsts11 content in the winter/spring and rsts11travel in the summer/fall), I’m hoping to get a more balanced content load out there for you this year on both blogs.

You can see the new year’s post for rsts11travel, my travel-themed blog, over on rsts11travel of course.

Looking back on 2018

Looking back on rsts11 for 2018, our top-viewed posts were a bit surprising to me.

Test-driving third party optics from StarTech in the RSTS11 labs

Disclosures at the end, as usual.

This fall John Obeto asked if I’d be willing to try out some third party optical modules in some of the varied and random switches I have around the rsts11 home lab. Always willing to help a friend and try some new gadgets, I accepted the challenge. Today I’ll give you an idea of why you might consider third party optics for your switching, why you might not, and how the compatible modules from StarTech.com impressed me.

2018-12-01 14.02.27WHAT ARE OPTICAL MODULES?

First, a word on optical modules. For decades, switch manufacturers have made two kinds of ports on their switches, a fixed port and a modular port. Fixed ports were long popular on line cards, where you wanted to get 24-48 (or more) optical ports for fiber cabling into a small amount of space, and you knew your customer was not going to change their optical requirements on the fly.

Modular (or “pluggable”) ports, however, made it possible to sell switches at a lower initial cost and allow the uplinks to be populated later. It also enabled customers to use different connection lengths and media with the commensurate power considerations.

In Gigabit Ethernet (and 1/2/4 gigabit Fibre Channel), the standard has been the Small Formfactor Pluggable, or SFP, module. About the size of a AA battery or a small USB flash drive, it connects to a small blade port inside the switch, and “translates” the connection to short (SR), long, (LR), or extended/extreme (XR) range optics, or even to 1000Base-T copper.

For 10 Gigabit Ethernet (and 8/16 gigabit Fibre Channel), the standard is an extension of the same module called SFP+. Many installations within a rack or in adjacent racks will use copper SFP+ cabling (with no fiber involved), sometimes called Direct Attach Copper or DAC cabling. Continue reading →

Warming up the HP Microserver Gen8 and PS1810-8G switch

Microserver Gen8 with PS1810-8G switch, Hershey bar for scale.

[This post was started in April 2017 and, like the gear it describes, the post was shelved for a while. I recently took the Microserver and its matching switch out of the dark recesses of the home office closet and brought it up to date. The upgrade report will follow later this month.]

Quite a while back, I acquired a HP Microserver Gen8 – the Ivy Bridge-based successor to the very popular N40L and N56L models. is model has been replaced by the Gen 10 model, but is still quite serviceable in its own right, and can be found on eBay for $500 and up depending on configuration.

The Gen8 Microserver comes with one of four dual-core CPU options (pictured below from the spec sheet; see Intel ARK for comparison); if you care about PCIe 3.0 vs 2.0, you’ll want the configure-to-order Xeon option or a warranty-voiding aftermarket upgrade. Folks on various home server forums have validated the E3-1230v2 ($75 on eBay), 1260L (from $57), and 1265Lv2 (from $100) processor upgrades (Intel ARK comparison), although the latter may push the cooling envelope a bit.

A (Dell) Precision replacement for our Intel NUC desktop

Posted on by

I didn’t really expect to be writing another build report so soon for my primary desktop. But in October of this year, it seemed to be time for a hardware revamping for my primary home desktop.

About five months ago, I built a 7th generation core i7 Intel NUC with Optane technology to replace an older 3rd generation desktop. That system ran a dual-core, quad-thread i7 processor, 32GB of DDR4 laptop memory, a 32GB Optane drive, and a 2TB solid state hybrid drive (SSHD).

Well, after three months I still felt the pain of a dual core system more than I’d expected. And in the meantime, my brother sent me a barebones Dell Precision Tower 7910 as an early birthday present. I was a bit concerned about it at first, since it uses Xeon v4 processors and DDR4 ECC registered memory, neither of which is inexpensive. The 1300 watt power supply had me concerned as well.

I decided it would be worth rebuilding the system anyway, since I could easily sell the system if I chose not to use it, and it’d be fun to run a more modern workstation for a while if I did decide to sell it. Spoiler: I am not planning to sell, but I’ll share the build report here so you can think about the options in case this meets your needs.

Curious Caveat

I had written most of this post, but when I went to confirm pricing, I realized that I’m running non-registered, non-ECC RAM in this system. Despite the documentation saying UDIMMs are not supported, and Crucial’s compatibility list showing all ECC Registered RAM, the parts I’m using are unbuffered non-ECC non-registered DDR4.

This may not be an optimal configuration, but if the cost and availability work better for you, it may be worth a try. Note that you will almost certainly be unable to mix registered and unregistered DIMMs, and you won’t be able to mix LRDIMMs and regular RDIMMS.
