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.

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

Experimenting with Intel Optane at home with the Intel NUC 7th Generation PC

Welcome back to rsts11 for the summer. We’ve got a lot to cover in the next few weeks.

I haven’t really done a build report in a while, so when I realized I was getting double-dinged for high power usage, I started looking around for ways to save power. One was my desktop PC, which while very nice (with 8 dimm slots and lots of features I don’t use), is using around 250-300W for a 3rd gen core i7 processor.

I decided, based on availability and curiosity, to build out a 7th gen Intel NUC (Next Unit of Computing) PC, which conveniently supports Intel Optane memory. You can read a lot about the Optane technology, but in this application it’s a turbo-charged cache for internal storage. The newer NUCs support it in place of a more conventional m.2/NVMe SSD (used alongside a 2.5″ SSD or HDD), and of course you can use it as an overpriced SSD if you don’t want to use the Optane software.

See my earlier post about an Intel NUC for use with VMware. That NUC is currently running Ubuntu and Splunk for training in the home lab.

I’ll take you through the build manifest and process, and then we’ll look at benchmarks for five configuration permutations.

Build manifest and current prices (July 6, 2018)

  • Intel NUC (NUC7i7BNH) tall mini PC, $450 at Amazon
  • (Optional: NUC kit with preinstalled 16GB Optane module, $489 at Amazon)
  • Intel Optane Memory flash module (16GB $34 – $39 at Amazon, 32GB $58 for Prime members or $72 otherwise at Amazon)
  • Crucial CT2K16G4SFD824A 32GB DDR4 memory kit is currently $310 (it was $172 when I bought it a year and a half ago, ouch).
  • HGST Travelstar 7K1000 1TB 7200rpm SATA drive is $57.
  • Seagate FireCuda 2TB SSHD is $92, with the 1TB version available for $60.
  • Keyboard, mouse, USB flash drive for Windows install, and living room television with HDMI were already in house, but if you’ve read this far, you probably have them and/or know how to choose them. After installation you can use a Logitech Unifying device or a Bluetooth device, but for installation I’d suggest a USB cabled device.
  • Windows 10 Professional can be had for $150 give or take. The actual software can be downloaded from Microsoft but you will need a license key if building a new system without entitlement.

You’re looking at about $1,000 for the full system at today’s prices. If you don’t need 32GB of RAM, stepping down to 16GB should save you at least $100. Continue reading

Coming back to the NetBeez monitoring service – a gigabit agent and more

[Disclosures at the end, as usual. Also, since this post was begun, NetBeez has announced discontinuation of their free tier of service. There is still a 30-day trial, though, so if you’re looking at deploying a paid option, you can still try it out first.]

At Cisco Live this year, I won a NetBeez monitoring agent (in the form of a Raspberry Pi 2 model B). It took a couple months, but I finally got it plugged in and running. NetBeez were kind enough to offer me an expanded license for a couple of devices, so I could run them from my home, my workshop, and possibly even a mobile rig.

See the previous article for how I started using the gear, and why I wanted to upgrade almost as soon as I got the first agent going.

B is for Banana – Pro, that is

With a 200mbit+ connection at home, and a 100mbit Ethernet port on my agent, I hit an obvious bottleneck.

Luckily, though, I’d stocked up on a couple of Banana Pi Pro devices, and had a Raspberry Pi 3 Model B as well. Since the only device I have a case for is the Banana, that’s what I ran with. I later realized the Raspberry Pi 3 is also a 10/100 device, so it would not fix the problem, although it worked fine as an agent on my backup DSL connection (which maxes at 20Mbps).

First look: Checking out the Netbeez cloud-based monitoring service

[Disclosures at the end, as usual. Also, since this post was begun, NetBeez has announced discontinuation of their free tier of service. There is still a 30-day trial, though, so if you’re looking at deploying a paid option, you can still try it out first.]

At Cisco Live last year, I won a NetBeez monitoring agent (in the form of a Raspberry Pi 2 model B). It took a couple months, but I finally got it plugged in and running. NetBeez were kind enough to offer me an expanded license for a couple of devices, so I could run them from my home, my workshop, and possibly even a mobile rig.

I’ll admit that I wasn’t completely sure what I would do with the agent, but once I got it going, I found a lot of utility in the offering.

Getting Started

If you want an utterly painless way to get started, win a pre-built monitoring agent at an event. The second closest option to that would be buying a preloaded agent from NetBeez.

However, for most of my readers, loading an OS onto a device you’ve had sitting in a pile in the corner of your lab or spare room is going to be as easy and a bit cheaper. NetBeez offers options for Debian Linux, OVA bundles for the virtualization platform of your choice, Raspbian for Raspberry Pi, and an Odroid C2 Debian image. There are probably other options you can work out if you put your mind to it, but it’s not much of a hindrance to getting going.

With any of these options, you’ll run an agent setup script with your secret code in it, given to you in an email (or in their dashboard once you’re set up–click on the gear icon in the top right of your dashboard). Then it should show up promptly in the NetBeez dashboard, and you can rename, configure, add targets, etc.

What I’m Monitoring

The first tests I put in were pointing at my home router (a Meraki MX84, see disclosures), and my remote workshop router (a Meraki MX60).

For my home router, I have a ping to the router’s internal interface, and a DNS lookup for one of the Meraki Cloud sites I would use to manage the Meraki environment. This validates internal connectivity and general DNS availability.

For the remote workshop router, which is connected over VPN, I check ping and http response to the internal interface of the router (which validates VPN connectivity), and ping and traceroute to the external interface (which validates Internet connectivity). Continue reading
