ISCSI Or NFS For Project
Aug 10, 2009
we are setting up a couple of servers for a clients application which will have 2 x 1U application servers running XenServer 5.5 and one NFS or iSCSI server (Dell 2950, Raid 10) running ether just Linux with NFS or Openfiler with iSCSI.
Would there be any benefit in running iSCSI vs. NFS considering their is no iSCSI accelerator and this is just a regular Server ?
NFS is simple but is it's performance really that much different than iSCSI in this scenario?
The network will be used by up to 12 user.

I am having a new mission to achieve and I really need some pro-Windows system to help me with their advices.
I have a server which requires high availability of data and service. Basically the server run a server/client service and all clients makes their operation over this server. The server is a simple Windows 2003 Web Edition server.
My goal is to have one server running (let’s say Tom with IP 192.168.0.1) and one running as stand-by (let’s say Jerry with IP 192.168.0.2) ready to take over if the first server crashes (this would remind pro-Linux some kind of DRBD and Heartbeat server).
So, the the first server run without problem, all transactions are going to be written in the directory “D:/Transactions”. This directory must be saved in real-time to the second server which stands in case of failure...
The first server also run a Windows service, which has to be stopped on the stand-by server and started ONLY if the first server is not working anymore.
I would like also the two servers (Tom and Jerry) to share a virtual IP address on the one which is having the service running, let’s say this IP would be 192.168.0.3.
When the first server goes offline hung or whatever, the second server take over, start the service and does the job of the first - when the first come back online, I re-sync the data from the second to the first and then, I switch it back (or all this fully automated if possible).
NOTE: the service that I need to run is special and is not one of the normal basic Microsoft service, it’s an in-house written service.
My question are :
- What software(s) do I need to do this ?
- Is there anything that I should be aware of ?
- Is there some provider (on both east and west) cost which can provide me help for the hardware part of this project ?

We are interested in launching a site dedicated to monitoring webservers and would like to know if there is a ready made solution for that. I know there are many tools like nagios, BB, cacti but what Im looking for is a program that is ready to be setup and will enable us to offer the same services offered by siteuptime.com, websitepulse.com, alertra...

My company has designed a test-run log parsing system.
Currently it supports
Code:
gLog currently supports the follow formats:
SSH(Proto 1,2)/Linux
POP3/Linux
Pure-FTP/Linux
Some logs you can currently upload are:
/var/log/secure
/var/log/auth.log
/var/log/messages
/var/log/maillog
We will be adding support for Windows Servers as well as Windows XP soon.
It will also be able to parse apache/lightd logs and check for common exploits such as: RFI/LFI/SQL.
Please upload your logs files to help this database grow.

I am trying to learn more about storage solutions over Ethernet. There are iSCSI (internet SCSI) and AoE (ATA over Ethernet). Certainly the AoE is a cheaper solution. Besides pricing, what are the advantages (and disadvantages) of each?

I'm colo'ing, so this wouldn't be shared with anyone else.
I'm looking at using iscsi with Virtuozzo Containers, and while the setup for the hardware nodes seems fairly straightforward, can anyone comment on their own experiences using iscsi with VZ?
Did you find your experience reliable? Slow? Any information will be useful.
Also, did you have a hard time setting things up? Or did VZ just manage everything as if it was still on a single server?

Thinking of putting together a ISCSI box with 14 sata II 750's, 3Ware sata controller (raid 6) and Intel quad port gigabit card ganged together for 4 gig transfer and tieing it all together with Open-E ISCSi or DSS module.
Anyone done something similar with good (or bad) results? Thing of using this for hosting web sites primarily as well as some storage for mail server and some databases. Servers running raid 1 and using MS iscsi initiator. Have a vlan setup just for iscsi traffic in my 48 port gigabit switch.
Are the TOE cards better to have or is the MS Initiator good enough. Plan on using the second NIC on the servers solely for ISCSI transfer.

I was trying to set up archive-my-tweets [URL] .... and I seem to have gotten stuck with a 403 error. When I remove the .htaccess file the 403 goes away but so do the rewrite rules so that's a problem.
You'll see the contained .htaccess file that's included in the project.
Basically for now I'm just trying to run this on my mac. I have set up the files in a subdirectory of my personal web server. The personal web server is working fine--but when I go to the /tweets directory I get the 403.

Has anyone here tried the Dell/EqualLogic PS5000 series iSCSI SANs? Any opinions on them? I'm looking to use two in a VMWare ESX cluster.
Also, does anyone have any more specific pricing than the 'starting at $19,000' that's been banded around the internet? I have an EqualLogic sales person visiting my offices in a week but would ideally like to get some rough pricing before then (eg: the price difference between SAS and SATA). Trying to get prices out of Dell hasn't been easy so far.

I setup an iSCSI target and two iSCSI initiators but I am having some trouble sharing the storage.
I partitioned the drive when I used the first initiator, a 1TB partition, I mounted it without any issues, it showed up in df -h.
Now I went to mount the iSCSI target on the second initiator, I mounted it fine, the partition I made on the first initiator was recognized on this one, however when I add files to either or, the changes aren't recognized on the other initiator. Any ideas why this might be?
I put 1GB of files in one initiator and I ran the df -h command on the other, and it still had the same amount of free space.

if anyone had any good recommendations for iSCSI products, either software or appliances for the small business market. We need good low cost SAN storage. I am looking at Nimbus and Open-E.

I´m thinking about using a centralized hosting solution, in order to achieve better redundance and performance while having more room to expand if necessary. In order to achieve this, I was thinking about implementing a storage server, and use a software to provide iSCSI target capabilities.
As storage server, I was thinking about using HP DL320s ( URL ), loaded with 12 147GB SAS HD´s 15K RPM. I will make some tests to understand the real difference between RAID5 and RAID10, concerning write speed. Also, I´m not sure if the controller provided with this server is good enough to provide a reliable operation.
For switching, I will use HP 2824 or 2848 Gigabit switch, and use port trunk in order to join both NIC controllers of the storage server.
As iSCSI target software, I still don´t know wich one to use. I think FalconStor would be a good bet, however it seems to be a bit expensive. Any good alternative?
This storage server would be used to provide storage for about 10 "regular" hosting servers, that have, at the moment, regular dual 10K SATA Drives (Raptor) in RAID1. I'm afraid the 2x Gigabit ports aren´t enough, even considering that I will not have intensive sequential reads / writes, but random acceses.

I'm currently connecting one of my servers to an iSCSI SAN but would like to hook up another server to that target as well. However, this doesn't work with NTFS filesystem and I couldn't really find any windows solutions for that. Does anyone have experience with this?

I´m running a Dell Powerconnect 6224 with firmware 2.2.0.3 for a customer.
After upgrade to firmware 2.2.0.3 from the version 2.0.0.12, and starting to use ISCSI with link aggregation groups, the switch began to reboot every 2-3 days.
Now, i have disabled LAG and this issue also happen.
It could be a firmware problem? Really, with firmware 2.0.0.12 it was solid as rock but without a advanced usage such as vlan, link aggregation, IP routing...
I´m not sure if my customer would like pay more and choose a more stable switch such as Cisco Catalyst...

Does anyone have experience comparing the two? Any comments on why one would be better over the other?
