Single-initiator zoning rule :--Each HBA port must be in a separate zone that contains it and the SP ports with which it communicates. EMC recommends single-initiator zoning as a best practice.Fibre Channel fan-in rule:--A server can be zoned to a maximum of 4 storage systems.Fibre Channel fan-out rule:-The Navisphere software license determines the number of servers you can connect to a CX3-10c, CX3-20c,CX3-20f, CX3-40c, CX3-40f, or CX3-80 storage systems. The maximum number of connections between servers and a storage system...
What is “Tier 0” in Storage Environments?
Tier "0" is not new in storage market but for implementation purposes it has been difficult to accommodate because it requires best performance and lowest latency. Enterprise Flash disks (Solid State Disks) capable to meet this requirement. It is possible to get more performance for company most critical applications. The performance can be gained through using Flash drives supported in VMAX and DMX-4 systems. Read More →
LUN to bind Restrictions and recommendations ----------- Any LUN You can bind only unbound disk modules. All disk modules in a must have the same capacity to fully use the modules' storage space. --- In AX-series storage systems, binding disks into LUNs is not supported. RAID 5 - You must bind a minimum of three and no more than sixteen disk modules. We recommend you bind five modules for more efficient use of disk space. In a storage system with SCSI disks, you should use modules...
The global reserved LUN pool works with replication software, such as SnapView, SAN Copy, and MirrorView/A to store data or information required to complete a replication task. The reserved LUN pool consists of one or more private LUNs. The LUN becomes private when you add it to the reserved LUN pool. Since the LUNs in the reserved LUN pool are private LUNs, they cannot belong to storage groups and a server cannot perform I/O to them.Before starting a replication task, the reserved LUN pool must contain at least one LUN for...
Lets talk about SRDF feature in DMX for disaster recovery/remote replication/data migration. In today’s business environment it is imperative to have the necessary equipment and processes in place to meet stringent service-level requirements. Downtime is no longer an option. This means you may need to remotely replicate your business data to ensure availability. Remote data replication is the most challenging of all disaster recovery activities. Without the right solution it can be complex, error prone, labor intensive, and...
TimeFinder/Clone creates full-volume copies of production data, allowing you to run simultaneous tasks in parallel on Symmetrix systems. In addition to real-time, nondisruptive backup and restore, TimeFinder/Clone is used to compress the cycle time for such processes as application testing, software development, and loading or updating a data warehouse. This significantly increases efficiency and productivity while maintaining continuous support for the production needs of the enterprise.¨ Ability to protect Clone...
