Page 4: Hp Solution Overview
hp solution overview Data integrity, reliability, scalability and high performance are top priorities in any database management system. The use of Network Attached Storage (NAS) devices to store database data files has traditionally been discouraged because it was thought that network instability and perceived vulnerabilities of non-local storage posed too great of a potential risk to data reliability and would greatly reduce system performance. -

fast and efficient data access, and utilizes RAID 0/1 or HP AutoRAID technology to protect the data on the storage subsystem’s hard drives. AutoRAID combines RAID levels 0/1 and 5DP, controlled and configured in “real time” by the VA 7xxx firmware, to provide total protection/recoverability in the event of single hard disk failures and almost all two (2) simultaneous hard disk failures (per redundancy group). -
Page 6: Nas 8000 Security Level Guidelines
usage plan calls for the use of NAS 8000 snapshots, space must be reserved in the volume group for the snapshots. After creating volume groups, the next step is to create file volumes. A file volume is somewhat equivalent to a file system. There are many possibilities at this level, and each choice should be weighed carefully before committing to an overall storage design. -

following: -T1807. The -T1807 specifies the setting of trace flag 1807, which is the trace flag that enables SQL Server to utilize "non-local" storage for database data files. Click on OK. It is possible to set trace flag 1807 through the Query Analyzer or through the use of ISQL or ISQLW rather than altering the startup parameters of SQL Server. -

would involve the use of the SQL Server Enterprise Manager in order to change the path to the database data/log files. Failure to correctly update all occurrences of the IP address could result in a database failure, or possible data loss. Whereas, if the network name were used, only the address in the Name Server(s) would need to be updated. -
Page 9: Share Level Security
share level security In Share level security, the NAS 8000 administrator, in conjunction with the SQL Server DBA can decide whether or not to password protect the CIFS share(s) that house the database(s). It is recommended that the shares that house the SQL database(s) be password protected and reserved exclusively for the database(s). Security on the share (or mapped drive) is handled when the connection to the NAS 8000 is initially made, not on every access to the NAS 8000. -

@ filename1 = '\\NAS8000\somepath\somefile.mdf' @filenamex = '\\NAS8000\somepath\somefile.ldf' The SQL command sp_detach_db takes the specified database "offline" so that it is in a consistent state and cannot be accessed by any user. Once the database is offline, its data/log files are available to be moved or copied. -

to 105 drives can be added to the VA 7400 (with DS2400 enclosures). The VA 7100 and the VA 7400 can contain a mixture of 18 GB, 36 GB and 73 GB hard drives. See below for details on adding hard drives to the Virtual Arrays. -

refer to the NAS 8000 Users Guide and the whitepaper NAS 8000 Backup Strategy (located off of the NAS 8000 home page) for further details on these solutions. There are four types of backup provided by SQL Server. In each backup scenario, the database remains available for user, although some operations are not allowed during a backup. -

seconds. The “Restricted” setting is the same as “Normal”, but allows the “immediate report” feature of write cache to be disabled as well as flushing the write cache for the associated LUN before completing the write request. The “Secure” Data Resiliency setting forces write cache to be flushed to the hard drives at a maximum of every one second, as well as allowing the “immediate report”... -
