Hello! Please, help me, I''m totally lost choosing basic budget server for XEN. The variants are Sun (X2200 M2 or Sun X2250 M2) or maybe HP Proliant DL160 G5p. Or maybe some IBM server? Which X2200 configuration will perform better, two Opteron dual-core 22xx or single quad-core 23xx? Which one performing better nowadays, Opteron or Xeon? I know that 2-3 years ago Opteron was the better choice for virtualization, what about now? Is Xeon 54xx better than Opteron 23xx ? Thanks in advance! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Or maybe some IBM server?I''d say go with whatever criteria that you use when picking normal server (e.g for standalone use). There''s not much Xen-specific requirements today, really. SUN''s Service Processor/remote management is the best one I found so far that provides serial access via telnet/ssh, so if you like fast command line interface over fancy HTTP GUI like I do this should be a plus. HP and SUN have wide selection of rack-mount systems with lots (as in over 12) onboard 3.5" SAS/SATA disk, giving you plenty of internal storage;IBM''s options are limited. Usually our company simply sets up an open procurement (works best when you purchase lots of servers at the same time), and let those vendors come up with offerings that fit our criteria (which includes onsite support/maintenance). Any one that can fit the ciriterias with lowest price wins.> Which X2200 configuration will perform better, two Opteron dual-core 22xx or > single quad-core 23xx?For scalability reason I''d say go with single quad core.

Very personal opinion:-
Target #1 Stay away from Sun''s Xen Hypervisor (even they will go up
3.3.1), unless you are within Sun.
Target #2 Be able easily install RHEL 5.3 (2) and port the most
recent MQs Repos from XenSource.org to your box in 2-3 hr.
Resume:-
In general, HP Boxes are preferable for RHEL & Xen ports.
If Sun''s boxes are good for Linux and Xen Linux Dom0 fine.
I just don''t know exactly.
You are not focused on Xen Software and i guess Xen Vendor been
selected is the most important

Hello!
Please, help me, I''m totally lost choosing basic budget server for XEN.
The variants are Sun (X2200 M2 or Sun X2250 M2) or maybe HP Proliant DL160 G5p.
Or maybe some IBM server?
Which X2200 configuration will perform better, two Opteron dual-core 22xx or

This gives you an HTML GUI/serial console and also a ssh interface (with access to the serial console). They can both interact with a serial console set-up in GRUB/inittab so you never need worry about failed kernel upgrades from a remote location.

I don''t really need hardware raid, I''ll go with software one & LVM. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This was before quad-cores came to market however. The big cache on Xeons is to ease the bandwidth constraints of the FSB. Opterons don''t have a shared FSB like Xeons, so don''t need the big cache. I''d take Opterons for server duties over Xeons without blinking, especially virtualization. -- Mike Williams _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Recently (on another thread on this list) I compared the performance of GPLPV network driver on Windows HVM domU (which is CPU bound, and its performance mostly depends on the speed of a single core) tested with iperf on Intel and AMD CPUs. Here''s the result (bigger=better) - Xeon X5450 @3GHz -> iperf = 1.4 Gbps - Opteron 2220 SE @2.8 GHz -> iperf = 1 Gbps They''re not exactly apple-to-apple (being from different year and different core-per-socket), but my point is today''s Xeon can match Opteron''s performance on the similar price range. There are other considerations though, like the fact that HP''s opteron-based DL185G5 can have more memory and disk compared to xeon-based DL-180G5. For most requirements (e.g. general one or two quad core CPU, 4-16GB) I''ll take whichever is available for lower price and similar performance (which tend to change on monthly basis) on my budget range, whether Intel or AMD.

At least for my workload, CPU power doesn''t matter very much. (I imagine for other workloads it matters quite a lot. But Xen handles oversubscribing CPU much better than it handles oversubscribing ram) What matters for me is how much ram I can afford. this is the problem with HP and Dell. Both are great if you order the low-end server, but they charge you two to four times what kingston would charge for add-on ram. I mean, it''s fine if you have the money and don''t want the bother of setting up your own ESD safe workstation, but it sounds like you are on a budget. Ram is what matters, for me at least. And for every density step above 2gb you pay about 2x more per gigabyte, so the number of ram slots is key. I always only buy motherboards that have 16 ram slots (or that support quad-rank ram, which is logically the same thing) _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

AMD should also be the only 64 bit processor that handles x86 (32 bit) instructions natively. It would be interesting to hear what all you dedicated Xen guys have to say about your experiences in this matter. AMD or Intel? There''s an interesting article at: http://it.anandtech.com/IT/showdoc.aspx?i=3484 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I know it USED to be so. Not now. http://en.wikipedia.org/wiki/X64#History_of_Intel_64 In the link you mentioned, the "native" part of "The only native x86 quad-core" might refer to quad core. AMD''s quad core implementation is real quad core, while Intel''s is simply two dual cores put together. PS: I thought this was an old thread?
