VMware hosts require few mandatory FA bits setting before SAN storage to be provision. Apart from FA bits a series of procedure require from installing HBAs, HBA Firmware and drivers, zoning, mapping, masking devices, to configure kernel files and devices. Let’s assume we have already identified Symmetrix FA port for VMware host and completed zoning on switch. It is better to have separate FA pair for VMware host. (You can connect VMware host to 2 pair FA if you have enough FA resources available and going to deploy critical...

In the current storage markets and technology, storage tiers are defined by availability, functionality, performance and costs. In fact data can move up and down tiers as time and business required.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...

Think when you are creating a point-in-time image for multiple devices. It is easy to create a point-in-time image of entire set of logical device at same time. In order achieve this you need to shut down an application so that no IO will occurs while you creating a point-in-time image. This is big problem in today’s environment where every company looking solution for zero down time.The EMC provided solution to this problem is called “Enginuity Consistency Assist”. When you create a set of sessions and invoke Enginuity Consistency...

Auto-provisioning requires Enginuity 5874 or later. It simplify Symmetrix provisioning by allowing you to create group of devices like storage group in CLARiiON, Front-End Port Group and Host Initiators Group and then associate these groups with each other in a masking view.The following are the basic steps for provisioning Symmetrix using Auto-Provisioning:-1) Create a Storage Group2) Create a Port Group3) Create an Initiator Group4) Associate the groups in a Masking View.Creating Storage Group:- It is component of Auto-Provisioning...
