HP microserver Gen8 Processor FAQ

http://homeservershow.com/forums/index.php?/topic/6596-hp-microserver-gen8-processor-faq/

This are a work in progress. After reading some other people's questions about processors for the Microserver Gen8, including "What's the best choice F or ESXi or HyperV use? "  I wanted to create some the sort of basic guide.  For those of your who is geeks, you'll love this. If you ' re ADD or in the TLDR crowd, skip this thread.

The HP microserver Gen8 comes with one of the processors stock:

The Intel Celeron g1610t (2.3GHz, 2MB cache, Ivy Bridge)

Http://ark.intel.com...-Cache-2_30-GHz

The Intel Pentium g2020t (2.5GHz, 3MB cache, Ivy Bridge)

http://ark.intel.com/products/71069

Neither is incredibly special, but for a home server running Windows Home Server, Windows Small Business Server, server E  Ssentials, or FreeNAS, they should do quite well.  Performance diferences should be minor between the.  But, what if you want to run virtual machines via a hypervisor like VMWare ESXi or Microsoft hyper-V Server? Neither of these, CPUs is exactly ideal, as they is missing some of the features of enhanced processors like vt-d INS  Tructions, the cache is small, and both have a CPU cores with no hyperthreading support. At the this point, an upgrade sounds like a good idea--but what does you choose?

The answer to the question all depends on how many VMs are want to run simultaneously on your hypervisor and what their PU  Rposes'll be. Tasks like SQL Server, Microsoft Exchange (in least, above a certain number of users), or an applications Server require M Ore horsepower than say, a basic domain controller (which even with DHCP, DNS, and other mainstream services, doesn ' t take A lot of load).

One of the requirements *is* purchasing a CPU with ECC support;  This negates many, if not all standard Core i3/i5/i7 processors. Note also, the Microserver Gen8 have a 150w power supply and a 35w TDP fanless heatsink design, something to keep in mind W hen upgrading--trying to slap in a 95w CPU probably isn ' t a wise decision.

The Microserver Gen8 has a Socket 1155 platform, and would support Xeon E3 (Sandy Bridge) and Xeon E3 v2 (Ivy Bridge) proce Ssors--xeon E3 v3 (Haswell) processors is a different architecture with a different socket (socket 1150) and is *not* s  Upported. IMO, these is the five processors to consider when upgrading the HP microserver Gen8:

Xeon e3-1220l (2 cores, 4 threads, Sandy Bridge)

Xeon e3-1220l v2 (2 cores, 4 threads, Ivy Bridge)

Xeon e3-1260l (4 cores, 8 threads, Sandy Bridge)

Xeon e3-1265l v2 (4 cores, 8 threads, Ivy Bridge

Xeon e3-1230 v2 (4 cores, 8 threads, Ivy Bridge-see caveats)

The L variants of the Xeon family is low voltage.  While the 1220L ' s is not as powerful, they is very low power (20w TDP for the SB, 17w TDP for the IB). This is great if you ' re only running-i-want to pack the server to the gills with other items (e.g.  than just the four standard drive bays).  The 1260L and 1265L pack more power, but has a 45w TDP, ten watts above the rating of the heatsink in the unit. Still very usable as others testing have found.

The Xeon e3-1230 v2 (4 cores, 8 threads, Ivy Bridge) is a fifth choice.  It is less expensive, and people has the do this upgrade with success. However, it has a 69w TDP, and I tend to be of the the conservative sort-I want as much power envelope left as possible for Other Devices (RAID controllers, extra drives, optical drive), and I also want a cushion that doesn ' t exceed the heat Remov  Al capabilities of the box. If you aren ' t planning the adding much to your server though, it is a good choice.

As for Sandy Bridge vs. Ivy Bridge, here's the basic rundown. The Sandy Bridge xeons has one basic advantage--their Heat spreaders is soldered to the CPU die using a fluxless solder  Process.  This provides to more efficient heat transfer. While the Ivy Bridge xeons would in theory run cooler if this process is used, Intel went cheaper, and now uses thermal p  Aste between the spreader and the die.  This means the Ivy Bridge processors actually don ' t run much cooler than Sandys under load, if at all. Note:if Modding is your game, some enthusiasts has managed remove the Heatspreader from Ivy Bridge CPUs, allowing Direc  T contact with the CPU die and lowering the heat, or replacing the thermal interface material with higher quality stuff. Do the your own risk-this voids your CPU warranty and could damage the processor.

On the other hand, Ivy Bridge processors has the following (Note:these may provide only negligible improvements Dependin G on the change)

PCIe 3.0 support (probably not necessary even when using a RAID controller or graphics card)

Improved Aes-ni instructions (if you is using encryption such as Bitlocker or TrueCrypt, this would is a plus, otherwise Negligible)

Improved floating point instructions

Improved Intel QuickSync performance. Note:not all of the processors listed has QuickSync (only the 1260L and 1265L v2 does) as not all of these has onboard GR  Aphics. Note also that due to the architecture of the Microserver Gen8 (which uses Matrox video rather than Intel Graphics as its Primary) that I ' m not aware that anyone have tested a quicksync-equipped processor to confirm that these features operate C  orrectly when such a CPUs are in the system. However, should they work, the 1260L and 1265L v2 has the potential to provide a considerable boost to video Encoding/tra Nscoding Performance If you use a application that supports it; The 1265L v2 'll has probably a 20-40% performance increase over the 1260L on this area.

Wikipedia also have excellent links if you search for "Sandy Bridge", "Ivy Bridge", or "Xeon" to explain history and Archit Ectural changes.

Note:something I did not realize until working more deeply today when replacing my Gen8 microserver ' s processor.

If you *do* wish to use Bitlocker or some other types of hardware encryption, one of the general requirements are having a  System with a TPM (Trusted Platform Module). Plenty of modern enthusiast mainboards has this;  The Microserver Gen8 doesnot. It is a purchasable option, with a general price of around $45-50.

HP's part number is 488069-B21, which are meant for broad compatibility across the GEN8 line of servers.  The part is a small daughtercard, connects to a TPM connector on the mainboard.  As part of the procedure, a plastic rivet are also used in the installation. This rivet holds the TPM in place, and was designed to deform or break if the TPM was removed, to make your aware that Securi  Ty has been breached.  Once the TPM is attached, it's paired to the mainboard for life, and should isn't be removed. Should HP need to replace your mainboard under warranty, and you should notify them the a TPM so they may provide yo U with a new one for the new mainboard; The original TPM should remain paired with the original board, per HP ' s own instructions.

The AES New instructions is still useful in some other applications, and if you is looking to does full disk encryption, Y Ou'll wish to purchase the TPM module as well.

Additional "should-work" processors:

Intel Core i3-3220t (2.8GHz, 2 cores, 4 threads, 35w TDP, Ivy Bridge)

http://ark.intel.com/products/65694/

Intel Core i3-3250t (3GHz, 2 cores, 4 threads, 35w TDP, Ivy Bridge)

Http://ark.intel.com...-Cache-3_00-GHz

These processors is among the rare subset of Intel desktop CPUs that support ECC memory;  You could think of them as very stripped-down versions of the Xeon e3-1220l v2. Both of these processors lack Intel vt-d, so they ' re isn't super choices for VMs hypervisor work;  Unlike the Xeon, they also lack Turbo Boost dynamic clock scaling for higher single-threaded performance.  They do bring hyperthreading and QuickSync to the table. If you ' re buying a brand new CPU, they wouldn ' t is on my list as I ' re already partway to the cost of a new or used Xeon E3; However, if you ' re pulling one from another system or come across one cheap, they would improve performance over the origin Al processors.

I ' ve had my 1265L v2 for about a month, it ' s been a great upgrade. I do think it was probably the best CPU upgrade for the MS Gen8, followed closely by the 1260L, and then (if low power is a Concern) the 1220L v2.

Either, I Haven ' t found that the 1265L v2 are causing a heat problem in my system. However, I was willing-spend more for a l-series processor over the Xeon e3-1230 v2 for the same reason your went with The 1260L; I considered a 24-watt TDP increase to being unacceptable for my configuration, especially considering the power draw and Pos Sible heat from other components.

Consider though, the reason for the L variant was low voltage, and therefore, lower TDP.  Keep in mind, the heatsink of the microserver are designed for a Max 35w TDP processor.  The Xeon E3 1220L v2 is well within this at 17w, of course, it ' s a 2-core/4-thread processor. The Xeon e3-1260l and 1265L v2 are 45w TDP processors; Above the envelope, but isn't significantly so, and they ' re 4-core/8-thread CPUs, quite a bit of processing power.

The Xeon E3 1220 v2 is 4 cores, 4 threads (no hyperthreading--and (like the Xeon E3 1230 v2 which are 4 cores, 8 threads)  It ' s got a TDP of 69w. That's 34w above the rated TDP of the heatsink, and at this point, I myself am isn't totally comfortable with the so idea, esp Ecially when you take into account the following:

-You're going to want to the load your system with drives, the most likely.  Probably all four bays, and maybe, if you ' re has fun, and the other has a schoondoggy drive bracket.  You ' ve got-to-look at thermal dissipation as a whole, not just from a processor perspective, and drives add heat. If you decide want performance drives (say, Western Digital re-series, Seagate constellations, or WD ' Raptors), the He  At goes up further still. Hardware RAID adds another CPU as well, and the CPU gives off heat of its own.

-Consider that the Microserver Gen8 have a 150w power supply. Start adding up what your Xeon E3 v2 (non-l) processor consumes under load, plus drives under load, plus peripherals (e.g.  , RAID controller or other expansion card) and at some point, you ' re putting additional stress on the power supply. Maybe it can handle it--but if you ' re putting it in the edge for periods of time, you ' re probably going to shorten its Li Fespan.

-Consider what your environment was going to be. If you ' re not in an air-conditioned house/apartment and you had warm summers, adding that heat to your server could pose an  Issue for a portion of the year. And there ' s much you can do to remove warm air from a device the size of a breadbox, with possibly limited channel s for airflow.

In the enterprise, people focus on reliability and uptime-and they focus on efficiency (keeping heat low, keeping power  Supplies within an efficient envelope) which also have a positive effect on that reliability and uptime. I know we ' re talking about home servers it's I ' m stretching it a tad, but it's always good-to-look at the what-a system was  Designed to handle. Personally, I think the Xeon e3-1220 v2 isn ' t a great value in terms of performance (no hyperthreading), or efficiency (69 W TDP) When it comes to the Gen8.

With my Xeon e3-1265lv2 I am satisfied (you need to decide what operating temp range is SATISF IED with) with the temp ' s I am seeing when I used the increased cooling setting in BIOS and has not considered DISA  Bling my turboboost. See:

I don ' t know of anyone in the Forums who have turned off the turboboost on their e3-1265lv2.

Please could your tell me if the e3-1270 V2 CPU are an option?

It'll likely work.  However, as mentioned before, I don ' t advocate 69w TDP processors in the Microserver Gen8. You ' re much better off with a 45w TDP processor; The passive heatsink is a designed for 35w TDP processors.

The 1260L should is one of the cooler running quad-cores due to the heatspreader being attached with fluxless solder to th  E CPU die. In comparison, the newer 1265L v2 which I am running probably would run warmer under load, even though it ' s a Lower-micron Process, due to Intel switching to thermal interface material between the spreader and die.

I have never lapped my HP heatsink. If the surface of yours is even, there shouldn ' t being a need, especially if you use quality thermal compound, such as those Available from Noctua or thermalright.

The Gen8 doesn ' t use the Intel CPU's graphics at all.  It uses the truly ancient Matrox G200 built in to the ILO chip. I doubt any modern Linux have drivers for a 15+ year old Matrox.

The only-to-get better graphics performance it to fit a real GPU in the pci-e slot.

Does the Micro Server support Non ECC RAM? (and therefore CPU)

No NON-ECC RAM, only ECC unbuffered RAM

Lowest Power CPU is E3 1220L v2 17w TDP, but either expensive or hard-to-come by

The GEN8 uses about 10W more than a more modern MINIITX machine with a fast Haswell CPU. The ILO and the extra are NICs use extra power, and the Sandy Bridge CPU uses more power.

For example, sitting in Windows with a single drive a g1610t Gen8 would use the about 35W.  An i3-4350 in a B85 board with the same RAM and drive would use 22W.  The i3 is dual core 3.6GHz with hyperthreading. The g1610t is dual core 2.3GHz.

The HP Proliant Gen8 is a great upgrade from the well known NXXL series. With the or three Systems you can build a reliable homelab and start to play around various VMware features. You can create a cluster, try VMotion, HA, DRS and resource pools or even create your personal vCloud or VDI environment. When you have a additional SSD, you can use a VSAN to transform the local storage into redundant shared storage. The server runs pretty quiet, so you can run it near your desk.
