Dedicated Data & Log Drives For Each SQL Instance?
May 17, 2007
For single instance installations I try to follow a standard configuration where our log files go to E, data files to F, tempdb to H and backups to G. With a new project we have decided to combine our Test and Dev environments on one server with Test being a default instance of SQL Server and Dev being a named instance. My plan was to stick with the above convention, but I was asked if it would be better for each instance to have dedicated data, log and tempdb drives. The problem is we would not have a dedicated controller for each drive. We would have one controller for the default and named instance data drives, one for the log drives and one for tempdb. The other issue is having to modify some of my admin scripts/procedures to work with different drive letters. That's now a real big deal, but does add more work to my plate.
Do you think it's worth having separate drives for a Test/QA server or is it typically sufficeint to use shared?
Thanks, Dave

I have a server that i would like to use as a dedicated DB Server. It is running Win Server 2k3 and SQL Server 2005. The typical upstream bandwidth is anywhere from 384Kb/s to 700Kb/s. Is this enough to host multiple SQL Server 2005 DB's?
The DB's will be used for database driven websites.
Please let me know what your thoughts are.
Thanks,

We are using the following configuration:
2 stand alone Windows 2003 servers 64 bit.
Each have two Gig Network cards configured with different IP addresses.
Each running multiple instances of SQL Server 64.
I am trying to set up a mirror where mirroring traffic between servers will be dedicated to a secondary IP address on the second NIC.
I am also trying to avoid Windows authentication.
Interesting enough: Security Configuration screen suggesting you to use fully qualified TCP addresses and, at the same time, does not give you such an option...
Would someone please point me in the right direction?
Thank you.

Can anyone point me to MS Best Practices that advise you against installing non-SQL-related applications on a SQL DB server? I feel it to be common sense but I have been asked to justify this with a direct statement from Microsoft. Help?

Hi all:
Give me some feedback.
In my company, we have 10+ sql servers and many sql jobs running on every SQl server.
What about the idea that running all jobs on a dedicated sql servers?
at least 2 advantages
1.easy to managment
2.if agent server down, we restart the server not to impact the downtime of the production server.
any suggestion is welcome.

Hi! need your help.
I have 2 dedicated sql servers xx.xx.x.155 and xx.xx.x.165 (Hosted Environment)
Both SQL Server 2005.
I need to replicate (snapshot daily) data from 155 (Apollo1) to 165 (Apollo2).
and I have many questions as this is the 1st time that I work on this environment.
I created 3 windows accounts and was able to create the publications (Apollo1).
Apollo1ReplSnapAgent
Apollo1ReplDistAgent
Apollo1PublisherUser
However (the distributor) is not visible to Apollo2 so I am unable to subscribe.
Do you have any idea what I need to do to make it visible?
I setup an ftp site to drop the publication (as I was unable to create an UNC Share) and I was hoping to be able to subscribe to it.
Probably it is a matter of permissions...maybe a firewall? should I ask my provider to open a port? do I need to create the same 3 accounts in the Subscriber?
something like Apollo2SubscriberUser?
Please help!
I am lost!

Hello all
I got a Problem when I try to store Data from a Flatfile to a DB.
The following Error appears in the Progress Control:
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Violation of PRIMARY KEY constraint 'PK_Products_1'. Cannot insert duplicate key in object 'dbo.Products'.".
I have a Flat File Source, and would like to store the needed records in a DB.
In Column 0 in the Flatfile I have multiple Entries with equal Values.
In the DB this Column is set as Primary Key and can only have one Record with the same Value in this Column.
How can I read out (or store) only one Record with the same Value from the Flatfile to store it in the DB?
How can I check if there is a Record from the Flatfile in the DB with the same value in the Primary Key?
How can I change any of the remaining Columns with different Values in the DB to match with the Flatfile?
Thanks in advance for any answer

All,
I was wondering if anyone could tell me why I could not connect to my server with the DAC when the server CPU utilization for all CPU's was greater than 90%.
BACKGROUND: I have successfully established DAC connections to this server in other periods when the CPU utilization was not pinned so high. I have done so by RDP'ing into the server, opening SSMS and cancelling the request to connect Object Explorer. Finally, I start a new query adding the "Admin" prefix to my server.
As I mentioned, when the server has CPU resource available, this works fine. This indicates that all the groundwork to setting up and using the DAC is laid correctly (i.e. DAC is enabled, I am connected locally, I am logged in with a user role with proper permissions, etc.).
This leads to my question. Why can I not connect to SQL Server 2005 Standard Edition using the DAC when all the (8-way) CPU utilization is at 90% or higher?
I need to make this connection to analyze why the server is so busy.
Any help will be greatly appreciated!!
Thanks,
Tom

I'm planning an SQL 2005 deployment and would like to know if an SQL server should be kept as dedicated as possible. Should apps that access SQL be kept on other servers? What are the do's and don't's along these lines? The plan here is to install everything that accesses SQL on the same server with the database, but this seems like a bad move to me. Am I right?
Thanks!

Hello all,
I hope someone can help with my current issue as i have now spent the last 8
hours trying to solve it! Here goes...
I am currently moving all my websites from our in house set up to a FASTHOSTS
dedicated server. Our in house set up consists of separate server for web
and data and works well even with my recent foray into .Net sites.
I have just moved the most recent of my .Net sites
(http://www.alfadealerads.co.uk/home.aspx) to the FASTHOSTS server and cannot
get the site to connect to the database (this has also been installed on the
FASTHOSTS server). One of the pages that connects to the DB is
http://www.alfadealerads.co.uk/links.aspx, where i am getting the error..
System.Data.SqlClient.SqlException: Cannot open database requested in login
'MasseratiChauffeurDrive'. Login fails.
Login failed for user 'lateral'.
This DB has been restored from back up from the original DB. I have
recreated the user name on the new SQL server and added it to the new DB
also. I am using a webconfig to connect to the DB, the exact same one
that works on my current live server
(http://www.maseratichauffeurdrive.com/home.aspx) only with the obvious change
to the SQL server name.
The only difference i can see in the 2 setups is that the new one has both the
webserver and the SQL server on the one machine and that machine uses domains.
My current in house setup does not use domains and as mentioned before web and
date are 2 separate servers.
Can anyone help? Or even understand what the hell i have written? lol
Thanks in advance

We have a database in SQL Server 2008 R2 with mirroring and want that replication is done by dedicated network.We stop the endpoint and when we try to run the following command, syntax error occurred:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '192.168.1.14'.
What is the correct syntax of the command line below?
ALTER ENDPOINT Endpoint_Mirroring AS TCP (LISTENER_IP = '192.168.1.14')

I am trying to run a program called NVivo7, which - when I install - also requires installation of SQL Server. Because my C drive is small (and nearly full), I am trying to run NVivo7 off my D drive, though SQL seems to install on C. Is it possible, do you think, to use 2 different drives in this way, or do both the program and the Server need to be on the same one? If so, is there any way to get them both on D?

So i'm not really new, but got a question. i've recently been looking to to the Western Digital Raptor Drives.
as far as performance, it's always been my understanding that the speed of the hard drive is just about always the bottle-neck of a computer. i'm currently running 2 stripped WD 500gb SATA drives for my SQL server (dual Xeon 2.8 with 2GB memory).
i'm thinking of upgarding to 4 WD Raptors (10k RPM) drives, the new 150GB models. anyone have an opionion? do you think i'll get a large performance increase?
the database that i run queries off of now is about 125 Million names, with about 80 fields in width. so it's rather large, and usally takes a fair abount of time to get my results back (we're talking anywhere from a minute, to half the day.)
do you think the raptors will slim that down significantly?

Hi,
Can someone help me, I installed SQL 2005 Enterpirse Editon on windows clustered servers. Then after the installation
I want to change the path of my DB logs but the problem was, I can not see the other drives. I can see only the drive where the DB was located. Is there any special configurations that should be done.
Thanks.

Ideally we'd like to configure our SQL cluster w/ the databases on one drive and the logs on another. Is this feasable in a cluster solution.. Will it basically just be 2 drives that are failed over vs. 1?

Hi, I'm looking for a way to check the free space left on the hard drives and then if needed send an alert to notify when we need to free up some space. I played around with the performance monitor and realized I could do it that way but I think you would have to leave the performance monitor running all the time and I'm not sure if I want to do that. I also read about the xp_fixeddrives proc that displays how much free space is available but then I don't know what to do from there? Does anyone have any recommendations for the best way to do this.

Hi,
I mapped a drive on to my SQL Server box. It points to another server from the same domain. When I try to backup or restore a database, I can't see this mapped drive through my SQL Server. Even if I type the entire path, SQL Server wouldn't take it. I don't have a clue about why it is not working. Can anyone throw some light on this. Your help is grately appreciated.
Thanks,

I have a SQL 2000 server that is installed on a Dual Xeon server running win2k. The server has two raid 5 hard drives, a C drive and an E drive.
The C drive is currently where the operating system files are stored as well as the SQL program files. As things stand there are SQL DB and transaction logs strewn between these two drives with no particular logic.
My question is, with two drives as it stands how should I move things around to gain the best performance? For example, should I keep all my data on the E drives and all my transaction logs on the C drives with the OS and the program files?
There are about 10 Databases in use. One database run's the configuration for proprietary predictive dialing software. The other databases are calling information for each campaign we run within the dialing software.
I have enough space on both drives to accommodate the data, its performance I would like to see a difference in.

Hi,
I have a SAN and configuring a cluster on SQL 2005. I initially created a Quorum drive when setting up the cluster and now added 4 more drives to the physical node but when I try to install SQL that drive cannot be located.
Do we need to create all the drives when installing the cluster or what is the way to add the drives later on.
Thanks

But when I choose "Attach", and open the requester to select the database-file, only drives C: and E: are shown.
All other programs lists the partitions right.
Where have D: and F: gone to ?

Environment: Windows Advanced Server with SP2. SQL 2K Enterprise edition with SP2.
There are three disk drives in my shared array named E:, F:, and H:.
When I use EM (Enterprise Manager) to create a job (like a backup job), the drop down box contains only drive F:.
Drive F: was the drive specified during the install process for data files.
Drive C: and D: also exist. Drive D: was specified during the install process for the program files.
It seems to me that drop down boxes in EM which show disk drives should actually show me the following drives: C:, D:, E:, F:, and H:.
Any ideas why EM may not be showing all the disk drives.
TIA solart

hi all
we have some servers connected in the same LAN, most of them with sql server. our production database is on a server with some several mapped drives (network drives). we have a maintenance plan which makes a database backup on one of this mapped drives, and also we make a backup of the transaction logs in another mapped drive.
recently we install another sql server on a new server and we are trying to create a maintenance plan in the same way as our production server. so we are trying to make backups in mapped drives. the server options are the same but the new server don't recognize the mapped drives...
is there an option or something that makes server recognize mapped drives or simply this server is not-well installed?
please, some ideas... :)
thanks & regards to all

Basically what I am trying to do is run bcp from within a stored procedure in SQL 6.5.
It allows me to dynamically assign the destination filename (the legacy application expects to see a file for each picking slip) I want to store the file on another server/shared directory on the LAN
Here is the code
DECLARE @ship_no varchar(16)
SELECT @ship_no = '1234567'
DECLARE @SQL_SYNT varchar(255)
SELECT @SQL_SYNT = "master.dbo.xp_cmdshell " + '"BCP AUSTCHAR..armaster out servernameBECpsqlout'+@ship_no+'.cba /c /t , /r /Sservername /Uuser /Ppassword"'
EXEC( @SQL_SYNT)
However I get the following output:
(1 row(s) affected)
(1 row(s) affected)
output
---------------------------------------------------------------------------------------------------------------------------------------------
DB-LIBRARY error:
Bcp: Unable to open host data-file.
The destination file is not created.
I have tried:
making the path the local HDD that works:
Using a mapped drive, that does not work
Running the same bcp command from the command line. That works.
Using UNC's (as above) You can see the result.
I have also checked security and made SQLexecutive ran as the domain admin. Did not work.
Can Anyone help?
Thanking you in advance

Are they're any real disadvantages or advantages in having 1 massive disk partioned to create 2 logical drives (not including the C drive) and separating the SQL Database File & Transaction Log so that it doesnt reside on the same logical drive?
After all, it is still a single disk.
thanks.
