Single loop outages will not cause DU Single loop outages will not cause DU More architectural details related to drives, cache, directors, cabinets, Mibe, SIB, Service Processor to come in the V-Max architecture expansion and modularity post over the next week. Devang has held several positions in the past including Sr.
Systems Engineer, Sr. He has been responsible for creating and managing worldwide technical support teams, technology solutions team, operations management, service delivery, pre and post sales support, marketing and business planning. In his current role Devang oversees multiple aspects of the Technology Solutions Group that works with various Multinational and Fortune companies providing them infrastructure services.
Loosing and Engine means the data on this DAEs is not available from other engines. Notify me of follow-up comments by email.

Remember the clarion drive styles, well the data stored in both the cases is different. DMX-4 does present some challenges Reduced mirror positions giving customers with mirror positions good flexibility for migration and other opportunities.
Minimum size DMX A single storage Minimum size V-Max SE single engine cabinet system, supporting drives system can be purchased with 1 engine can be purchased with a system and drive max. Backend ports per engine is 4 ports connecting System bay to storage bay.
Concept of Backplane exists with this V-Max fits in the category of Modular generation of storage Storage and eliminates the bottle neck of a backplane. Systems cannot be federated The concept of Federation has been introduced with V-Max systems, but systems are not federated in production or customer environments yet. No support for InfiniBand expected Would InfiniBand be supported in the with DMX-4 future to connect engines at a short or long distance several meters.
No Federation With Federation expected in the upcoming versions of V-Max, how would the cache latency play a role if you had federation between systems that are 10 to 10 meters away? Global Cache on Global Memory Global Cache on local engines chips: again Directors as cache is shared between multiple engines, cache latency is expected as multiple engines request this IO. DMX-4 is a monster storage system The V-Max building blocks engines can create a much larger storage monster.
V-Max performs better compared to 2. Diskless R21 passthrough device, no disk required for this passthrough. Symmetrix Management Console 6. EMC takes those 8 bytes — of calculation for data integrity T DIF standard proposal and writes it in blocks or chunks of 64K through out the entire drive causing performance degradation.
A and Fabric B Directors together. Email Subscribe to all comments by email Configure options Post as Guest. Has few times re-read for this purpose to remember. It can be configured with up to 64 front-end ports and a 1. With a VMAX3 engine and up to 1, disk or flash drives in a single rack, the box has a low footprint for the capacity. It can use FAST. It has the option to use EMC ProtectPoint software for direct backup to a Data Domain system, and also can optionally use data at rest encryption.
File services are embedded on the array, so it's easy to converge block, file and mainframe workloads. The Cache memory is mirrored between directors, and in configurations with 2 or more engines, it is mirrored between engines.
Internally, the engine components communicate locally, so cache access is local within the same engine. Virtual devices can also be used to form a VDEV metadevice. Other Symmetrix devices cannot be converted to form virtual devices. Thin devices TDEV are devices that may or may not have storage allocated to them when they are created.
To a host operating system, they look like regular devices with their configured capacity. The host treats them as regular devices and writes and reads from these devices like regular devices. Thin devices are bound to a thin pool of DATA devices. Following devices are contained in storage pool using virtualization technology.
Symmetrix SAVE devices work in conjunction with virtual devices and can be unprotected.
