VPN Hollander Powerlink Server issues

greatjubee — Fri, 08 Jul 2011 03:34:00 +0000

I set up a VPN connection to our Hollander Powerlink Server when I try to set up the client software I get and error message unable to validate the power link server. I have all the drivers mapped on the client machine.

during set up I try to map the SQL but I am having trouble making the connection to the server.

Please help as this is driving me crazy.

Storage Area Network Configuration IOPS

Rick Martinez — Thu, 13 Jan 2011 23:10:50 +0000

I have a SAN with a RAID 10 (16 Drives) and a stripe size of 512. I want to align the disks for better SQL Server performance, the problem is that the OS is already installed on a non-aligned drive and SQL Server is running in production using non-aligned drives. My current 8 drives starting partition offset is 32256 and the file allocation unit size is 4096. IOPS = 750 MB/sec = 13 Latency = 10ms Disk Queue Length = 7 Block Size = 20KB 1.Can I just align the disks where the SQL Server database files live? 2.Aligning only the drives where the SQL Server database files live would that create a bigger block size in IOPS? 3.Do I have to also align the drive where the OS lives? 4.Maybe the main question is what controls the block size that gets sent to the SAN?

SQL SERVER 2005 Storage Performance

Rick Martinez — Tue, 11 Jan 2011 18:30:43 +0000

We have an IBM server xSeries 460 with a QLogic FC HBA card 4gb on the server with a PCI-X 266MHz bus speed (16 CPU 667MHz FSB, 32GB RAM). The HBA card connects to a Brocade 5000 switch then to the SAN Controller then to a Cisco 9124 Switch then to SAN Drives all through FC. On the IBM server we have SQL Server 2005 installed on windows 2003 32-bit.

IOPS = 750 MB/sec = 13 Latency = 10ms Disk Queue Length = 7 Block Size = 20KB

Users complain that the application is slow all the time, I noticed the application is slow on reads only that is where our high latency comes from. I did see that on our Brocade 5000 Switch all other servers on the network are connected to that switch (mail server, report servers, other application servers) but connect to another SAN. There is only one application connected to the XIOTECH 7000 SAN and that is the application that is slow.

SQL Server 2005 Performance

1. How can I lookup the change rate of a database?

2. How can I check the percentage of calls to the database that are reads?

3. How can I check the percentage of calls to the database that are writes?

Database Log File sql server 2005

Rick Martinez — Thu, 05 Aug 2010 16:35:19 +0000

We have a 500GB database, we use a san server with 16 drives. Eight drives are for storage and the other eight for mirroring. All eight drives is one RAID 10 and within that RAID 10 we partition the drives into 8 drives (please seee below) we are having so much slow performance on the application are we storing sql data files correctly on the SAN?

Drives on SQL Server:

C = OS X = SQL Database Files (MDF) Y = File Storage F = SQL Backups D = 500GB Database, SQL Server System Databases I = 500GB DB Indexes L = SQL Log Files T = SQL Log Files

How to use Insert command between two servers to speed up performance

Studentofsql — Sat, 17 Apr 2010 16:34:45 +0000

We need to take data from a table on one server and write it to another in the fastest way possible. We tried Insert command and it worked perfectly as long as it was running on the same computer. When we tried to use it to update another computer/server on our network, none of the data got there.
If you have a way to do this please show an example. Thanks in advance.

Bulk-Logged Recovery Model SQL Server 2005

Rick Martinez — Thu, 20 Aug 2009 17:06:08 +0000

If I change the recovery model on the database from full to bulk-logged to run DBCC CheckDB and Rebuild Indexes is changing the recovery model the correct thing to do?

Performance issues with a large table in SQL Server 2005

Thecoolestguy — Sun, 17 May 2009 00:11:01 +0000

I have an application that is managing inventory for a company that has multiple locations. Items are being inserted into an inventory table roughly every 5-6 seconds from three locations.

At the same time, this company is packing inventory in boxes in order to fulfill orders. I have a table setup for this in which inserts are made for an inventory id and a box id (tied to a purchase order table) to show when an item has been packed and is no longer in inventory. Roughly 6000 items are being added per day into inventory as well as being shipped out of inventory.

Before an item is being shipped – I have to first check the inventory table to make sure the item exists in inventory and also need to check the shipping table to make sure the item hasn’t been shipped. I’m also checking these tables on the sales side to verify when an order has been completed. These two tables are being hit every few seconds both with reads and writes.

I’m running into some performance issues as the size of my table is growing. I’ve been researching the problem and have a couple of ideas on how to fix this – but wanted to check here first to see if I’m on the right track.

1. Indexing this table in order to get better performance during the lookups. From what I’ve read, this will improve the select queries – but will slow down the inserts since the table will be re-indexed after each insert. Since I’m inserting into these tables every couple of seconds – I’m wondering if having indexes on these tables might degrade performance instead of improving it.

2. The queries are being performed via my application. Ie, a query checks to make sure the item is active in inventory – results are returned to the application and either an error is thrown or an insert statement is re-submitted to the SQL server. By moving this into a stored procedure – I’ll remove the network traffic associated with going back and forth between the application server and the sql server.

3. I’ve read a little about partioning and it sounds like this might help (ie, partioning on each of the location id’s) – but I have not gone into it enough to really know enough about it.

Hopefully my question was clear. Any advice or suggestions are appreciated.
