You need the low profile bracket for a Microserver. When you look for a memory module for it, search for the battery. Many times salvage companies leave the module connected to the battery, not realizing they are two separate parts.

Looks to me that the cards are the same size, just the brackets are different ... you want to get the one with the shorter bracket!

Have you used a P410 before? If not here is a link to manuals and guides; http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&lang=en&cc=us&docIndexId=64179&taskId=135&prodTypeId=329290&prodSeriesId=3883890 Here is the link to drivers and firmware. I find it is best to run the latest firmware; http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=3883931&lang=en&cc=us&prodTypeId=329290&prodSeriesId=3883890&taskId=135

Use the search feature to look for Lone Wolf's postings -- he has done a lot of work with his setup with a P410.

 

you could start at http://homeservershow.com/forums/index.php?/topic/4682-odd-disk-layout-after-first-time-ws2012e-installany-advice/ but certainly dont' stop there.......

Nice post dude; really helpful I think.

I am currently using a P410 in my Microserver; as others have said, you do indeed need the low-profile bracket for the card to fit properly, at least if you wish to firmly anchor it in (you could technically remove a full-height bracket and use the card).

 

You definitely want a cache module; if you haven't bought one, I'd be happy to send you a 256MB one for the price of shipping, as I have two lying around. 512MB and 1GB ones are also available. There are four types of cache modules:

 

256MB (with optional battery backup)

512MB (optional battery backup)

512MB (flash-backed)

1GB (flash-backed)

 

A battery backup module or (in the case of the flash-backed models) capacitor module is necessary if you wish to safely use write-back cache, although you can override the default write-through cache without a battery (not recommended unless you have a UPS at the very minimum, as this risks file corruption in the event of a power failure). The flash-backed modules have the advantage that there is no battery to wear out over time; the capacitor module (which looks much like the battery module) only needs enough energy for the cache module to write changes to flash. Also, a battery module will lose charge if a system remains powered down too long after power failure; the flash-backed write cache can hold data indefinitely.

 

The 256MB cache is 40 bits wide in its memory path; the 512MB and 1GB modules are 72 bit, so for heavy or sustained I/O, the larger cache modules are higher performance. Also, a cache module (of any size) is required for RAID-5.

 

HP has excellent driver and firmware support for the P410 controller; make sure you update the firmware on your card to the latest prior to using it. Also, I recommend downloading HP's .ISO of their Offline Array Configuration Utility (ACU) for configuring your logical drives after the BIOS update and prior to setting up your operating system. If you have further questions, let me know.
