The specific Performance monitor counters that measure I/O latency in Windows are Avg Disk sec/ Read, Avg. It doesn’t appear to be a significant performance difference for SQL workload, but it would be something interesting to test. The metric commonly used to measure slow I/O performance is the metric that measure how fast the I/O subsystem is servicing each I/O request on the average in terms of clock time. Nimble Storage provides a high-performance, fault-tolerant storage platform that is fully compatible with Microsoft clustering. Microsoft SQL Server databases provide the data storage back end for mission-critical applications. Refer to the Microsoft SQL Server documentation for the version of your database software, the SQL Server 2008 R2 documentation is located at the following link: ( In addition to SQL Server native backups, use Nimble snapshot backups to provide replication functionality for disaster recovery. ![]() Because of this, most people prefer to still set it at ESX 5 policy. Nimble Storage Best Practices for Microsoft SQL Server. It includes a relational engine that processes commands and queries and a storage engine that manages database files, tables, pages, indexes, data buffers, and transactions. Down the road someone might storage vmotion some non-SQL workload onto that datastore, or just start using it for non-SQL workload. The core component of Microsoft SQL Server is the SQL Server Database Engine, which controls data storage, processing, and security. This can be a difficult thing to control. "If you are sure that only SQL data is going to be put onto a datastore, it’s best to use the SQL performance policy. This best practices guide provides a multi-protocol file sharing NAS solution for both Windows and Linux systems that still leverages the power of Nimble Storage performance and scalability. Replicated volumes contain the contents of a volume at the time when the replica was created or last updated, as well as a configured number of retained snapshots. They are a little torn as well and after some debate amongst themselves i received a reply like so: HPE Nimble Storage replication makes it possible to copy a volume or a set of volumes to another HPE Nimble Storage array, called the replication partner. I sent an email to a nimble engineer requesting their opinion. I see where he is coming from and it makes sense but i still had a nagging feeling about the whole thing. ![]() My coworker says because its presented to esx and not presented directly to the server with iscsi software that we should be using the esx 5 performance policy and not the sql performance policy. I had it setup so that the sql server was on a sql lun with a sql server performance policy and the log drive was on a separate log lun using the sql log performance policy. ![]() A coworker and I are disagreeing upon which performance policy to setup for our SQL lun on our nimble san and I figured I'd turn to you guys and get your opinion.
