disk alignment question!

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :

Brand new sql cluster installation, setting up the disks.

Windows 2008 R2

SQL 2008 Enterprise

Dell 610 x2 (active/passive cluster)

Dell Powervault SAN - 8x450GB 15k SAS - RAID5

OLTP system with pretty even read/write ops

How do these number below look?

128KB stripe size

64KB cluster size

1024KB offset

Are my alignments correct? Should my stripe size be bigger since 8 disks? I am new to this and still don't quite understand the formulas.

Confused about Disk Alignment/ Partition Offset

I am all confused by disk alignment, partiton offset.Why do we need to calcualte offset which most of the articles talk about, This is from White Paper  Disk Partition Alignment Best Practices for SQL Server where its stressed that Partition_Offset ÷ Stripe_Unit_Size-- should be an integer 'The performance question here is usually not one of correlation per the formula, but whether the cluster size is the NTFS default of 4,096 bytes or has been explicitly defined at 64 KB, which is a best practice for SQL Server.' Also how do we calculate Stripe Unit Size for SAN. Thanks all for your replies !!  

Disk Partition Alignment SQL 2005 on Win 2008


Needed some help for Win 2008.


Gives info about disk partition alignment. It states that Win 2008 'ATTEMPTS' to get the partition aligned for us.

If I run,

fsutil fsinfo ntfsinfo e:

on our Win 2008 server, it still gives the partition as 8KB. Do, we need to change it to 64KB?

Question for DBAs: Trying to achieve parallel disk IO with a single disk array controller



I am thinking to consider this disk array controller: (http://bit.ly/a0egr2) for my SQL Server 2008 database server (http://bit.ly/dcphU7). The server is going to have 12 physical hard disks and my plan is to configure the controller to have four drives on my windows 2008 server:

Avg. Disk Sec/Read question


Hi guys,

My disk consits 16 disks for RAID10, the Avg. Disk Sec/Read is 19 ms, is it ok?

Here is MS recommendation:

Less than 10 ms - very good
Between 10 - 20 ms - okay
Between 20 - 50 ms - slow, needs attention
Greater than 50 ms – Serious I/O bottleneck

Not sure if I can use the value directly to evaluate the performance of RAID disk without calculating the number of disks and RAID mode.

Less than 20 ms is ok for any kind of RAID consists any amount disks?

Any suggestion would be appreciated.

Using DISKPART for disk alignment and understanding the output


I understand that in 2008 server it'll align the disks for you automatically.  I've run the following commands on another one of my DB servers and the offset was 1024 on all of them.  I get the following from my other DB server and it doesn't list the alignment on every partition save the first one.

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------
  Partition 1    Primary            100 MB  1024 KB
  Partition 2    Primary             39 GB   101 MB

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> list partition

  Partition ###  Type              Size     Offset
  -------------  ----------------  -------  -------<

file upload in chunks or not buffering in memory before writing to disk?


What are the options for handling file uploads to reduce the memory footprint?  Is there a way to upload in chunks?  Is there a way to stream upload directly to disk instead of loading entire file in server memory?

Web Site to Web Application Question


I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?



connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview? 

database interface design question


For handy database interface, is it good to use SqldataSources exclusively intead of EntLib functions?

Thanks for any feedback.
