NexentaStor ZFS Bonnie++ Benchmarks

Following on from my previous post regarding AFP and iSCSI benchmarks i’ve decided (after many requests) to post a few raw benchmarks of the system gathered by bonnie++, the environment is as follows:

CPU: Athlon 64 3700+
RAM: 2gb DDR400
Controllers: 2x SATA-II and 1x SATA-I
Hard Drives: 7x Samsung 2tb Spinpoint F3 5600 RPM
OS: NexentaStor 3
ZFS Config: Standard raidz1 with dedup=off and compression=off

So I gathered a few results… after some annoying results I found a bottleneck in my system on 1 of the drives that seemed to bring the benchmark result down greatly, however once this was worked out I acheived the following: … 

 

NexentaStor AFP & iSCSI Xbench Benchmarks

UPDATED WITH BOTH iSCSI & AFP RESULTS

I’ve recently setup a ZFS raidz with 7 disks using NexentaStor, natively this doesn’t come with AFP, but I managed to get a package and get this all working (which i’ll demo in an upcoming tutorial), one thing i noticed however is that I could never find any benchmarks that tested the general use of a NAS… i.e. using CIFS or AFP over a network to another machine and testing performance. There are literally 0 AFP benchmarks for NexentaStor due to its non-native support. So here it is

Test Environment:

NAS: 7 SAMSUNG Spinspoint F3 2tb Hard drives connected via SATA & SATA-II, in a ZFS raidz running on NexentaStor 3
Network: 1000BaseT Gigabit LAN
Test Machine: MacMini with 1gb memory (disk tests are cached in memory for speed) running XBench to benchmark

Samsung F4 EcoGreen F4EG Firmware Bug Patch

Many people already know that the Samsung green drives have a bug in the firmware that may cause data loss, Samsung have created a patch that you need to create a bootable floppy disk along and drag in their file, if like me you don’t have a floppy disk drive & don’t want to mess around with USB booting and creation of a drive or just cannot boot from USB then you’ll need another solution, i’ve put together a quick bootable CDROM ISO that contains freedos and the patch, simply boot and type F4EG and hit enter, the patch will automatically detect your drives and update them. I hope this helps people out as it did me. As quoted from the original site:

“If identify commmand is issued from host during NCQ write command in the condition of PC ,
write condition is unstable.

So It can make the loss of written data.”
(Model : F4EG HD204UI, HD204UI/Z4, HD204UI/UZ4, HD155UI, HD155UI/Z4, HD155UI/UZ4)

Bye Bye FreeNAS hello NexentaStor

Well, i’ve used FreeNAS for around 2 years+ now, and all has been good, however, in that time demand for large quantities of storage has now been joined by demand for high speed storage; Once I had replaced all of my drives with 2tb 7200rpm drives I realised that FreeNAS wasn’t giving me the performance on each drive that i’d like.

Welcome NexentaStor… a storage appliance natively supporting ZFS as its based on OpenSolaris! NexentaStor offers many of the same features of FreeNAS, however at a greater level of performance. This comes at a cost though, the free Community edition is limited to a some what large 18tb, whereas the paid version will cost you.

Also NexentaStor is a pure storage appliance, although it supports CIFS/iSCSI/NFS and the likes, it does not have all the bells and whistles of FreeNAS… but for me, there is no use having all these features if I can’t have the speed.

I’m installing NexentaStor now as we speak, after which I’ll be posting a review / tutorial on NexentaStor after i’ve got it up and running and configured to my liking 🙂 I hope you enjoy it!

 

Amazon Support Store

Hi everyone! I keep getting lots of emails from people asking where they can buy xyz to complete the tutorials and try out some of the things listed on CaptainGeek, well after I kept emailing people the same links i had a thought, why not setup an amazon affiliate store. Basically, i’ve setup a small amazon site with a small selection of products (only those used for the tutorials on this site + related ones), purchases and payments are handled by amazon, however a small percentage of the sale goes to helping fund the server this website is hosted on AT NO EXTRA COST TO YOU 🙂 so its a win win situation, please use the links whenever you can.
