Posted by: Denny Cherry
Cache, SQL Server, Storage

The short answer is as much as possible. The more exact answer is you typically can’t allocate cache to a specific LUN.  You can usually carve up the total amount of cache into read and write cache.  You want as much write cache as possible so that the database writes directly to the disk as...

What are your opinions on using an iSCSI NAS for SQL Server storage?



Posted by: Denny Cherry
iSCSI, SQL Server, Storage

You’ve really got two questions here.  The first is if I like iSCSI for SQL, and the second is if I like NAS for SQL.  NAS doesn’t support iSCSI as iSCSI is a SAN technology. iSCSI is just fine for SQL Server as long as the server and the storage are on the same subnet, and the network has...

Moving data into the cloud is a huge thing with Microsoft and Amazon (among others).  However for those in countries that aren't the US there are some major road blocks to putting your data into the cloud. The first issue is that when the cloud provider is a US company (which most of them are...

We are currently running on an EMC SAN. Did I hear you correctly, we should have databases, backups, temp, and logs on the same LUN? Thanks.

EMC, SQL Server, Storage

No, you want to put them on different LUNs.  IBM is currently recommending that on the XIV array that everything can be put on a single LUN as the LUN is spread over all the disks in the array.  For an EMC array you’ll want to have separate LUNs for each. Denny
