Hi there I''m busy with some tests on the above hardware and will post some scores soon. For those that do _not_ have the above available for tests, I''m open to suggestions on potential configs that I could run for you. Pop me a mail if you want something specific _or_ you have suggestions concerning filebench (varmail) config setup. Cheers This message posted from

Dear list, we have a relatively new Sun Storage 7310, where we connect CentOS 5.5 Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades boot from SAN via qla2xxx, and have no harddisks at all. We want them to use multipathing from the very beginning, so /boot and / are already seen by multipathd. Problem is, that the Sun 7310 has two storage heads which run in active/passive mode. BUT the multipathd thinks, they...

Hello, I want to implement a diskless xen hypervisor. The way I suppose it will work is xen booted over pxe and getting iscsi san storage to store vm images. Is solution like that usable ? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

...50. They are all mostly idle. I can observe that when some network traffic is going on with the Windoze machine, it causes a CPU load of 200%. "Some network traffic" means that virt-top is showing 1M/2M RX/TX. Considering that the bonding interface is theoretically capable of handling 4Gbit full duplex, the 3Mbit are neglectable. Virtio drivers are being used. Currently, virt-top shows 1.9% CPU for the Windoze machine and top shows 22% CPU load for the corresponding qemu-kvm process. There is almost not network traffic. The VM has 4 CPUs assigned. What may cause the high CPU load?...

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance. Unfortunately, I am hitting some sort of write bottleneck and I am...

Hi, I wonder about the performance of a Linux box used as router (I guest I''m not the first :). Althought I know it mainly depends on the hardware, I''m trying to find some references on the topic or comparations with other routing solutions (FreeBSD box used as router, Cisco, etc). For example, http://facweb.cti.depaul.edu/jyu/Publications/Yu-Linux-TSM2004.pdf (althought is

We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and... Specifically for the slog and/or cache??? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I''ve a local LAN consisting of about 150 machines. I''m using a Linux machine as the gateway machine which inturn connects to two different ISPs. My question is can a Linux based machine match the performance of a hardware based routers provided by Cisco,... OR is my decision to go for a Linux based solution is a wrong one?. Is there so much difference between these
