    Low-end NAS boxes are almost always CPU bound. That’s why I don’t fool around with SSD or RAID1/0 on them: not enough value for the cost uptick. If you’ve got some 7200RPM disk to try, that would make an interesting counterpoint, especially on the iSCSI test.

    Such iops for a “lab” are quit nice 🙂 And the latency make me drewl .. Over here around 2-25 ms, with spikes upto 220 ms. Make me wanna upgrade my nexenta vsa (raidz1 3x 2TB 6G sata) with a ‘tier1’ pool of dedicated ssd’s

    I went with the DS1512+ because it’s only slightly more expensive, yet has much higher build quality (metal rather than plastic enclosure and integrated power supply), with a faster dual-core CPU and upgradable memory. Plus you can expand it to 60TB! The three-year warranty doesn’t hurt either 😉

    I’m running iSCSi but will try NFS. Thanks for the research, Chris!

    BTW, Chis, I followed your Lab recipe to the letter. Works a treat! I love the Supermicro’s built-in KVM, since I am running my lab in a colo. You’re super for sharing your design!

    Good data. I’m using a DS1512+ with iSCSI primarily. I may look at trying an NFS datastore.

    I have resently bought a synology 812+ device to hold my VMs. I cant decide weather to use NFS or ISCSI. according to your write out i should obiously use NFS.

    would you advice that i use NFS or would it be a different case for me as im using a different device.

    thanks in advance

    Did you happen to try this on iSCSI (Regular files)? Just curious if that helps since you can enable VAAI with that option.

    Hi again,

    i dont get it, i just ran I/O tests on my Synology RS812+ NFS drive and i got the following results:

    1.4KB 100% Random 100% Read – 1228 IOPS
    2.4KB 100% Random 0% Read – 994 IOPS
    3.512KB 0% Random 100% Read (Throughput Test) – 36 MBps

    Considering i have a newer Synology then yours should i be experiencing at least similar results to yours?

    I have my P.C attached to the synology RS812 via a 1GB network.

    any help would be much appreciated. Thanks

    I’m considering a similar setup but using Raid1-SSD:s instead. iSCSI is must since I’m planning to place clustered SQL Servers on the device. Any thoughts on this?

    Hey Wahl! Got a question for ya…. Are you still using iScsi on your DS2411+? I recently purchased a 1813+ and the Latency i’m seeing on my esxi hosts over Iscsi is just abysmal. Spikes of up to 33000MS! But averaging around 80ms. This is only with 3 VMs running on the box as well. Network is not the bottleneck. This is across a raid 10 of 6x 2TB 7200 RPM HDDs with 2x 256gb samsung 840 pro cache drives. NFS does not have the same problem. And it appears that the CPU is not the bottleneck either. This is all on the DSM 5.0 beta U1. If you have any tips to share from your home lab I’m all ears! Love the blog by the way!
