At the beginning of the year, unless you have been hibernating, it has been difficult miss the launch of 41 new products including EMC VNX. The least we can say is that the timing of such a set of projects has not been an easy task and we can only recognize the strength of the company in this field. Now that the noise begins to sink and I had the chance to evaluate a product, let us focus on this new range VNX.
View of VNX 5300
Physically, it remains in the presence of X-BLADE equipped with the famous "DataMove" Disk Processor Enclosure related (Storage Processors) which is connected Disk Array Enclosures by the traditional ties of CF and a control station redundant
First it must be said that the VNX want to convergence between its two previous ranges midrange Clariion called (SAN-block) and Celerra ( NAS-file mode) to provide functionality that is unified access protocols FC / iSCSI / COEF / NFS / CIFS in a box, all driven from a common GUI called Unisphere Manager federating access to well-known features of DART ( NAS) and FLARE (SAN). The controllers function as it should be active / active support and co ALUA PowerPath software house that allows for dynamically load-balancing and failover.

Some developments in the firmware FLARE 31 in which there is support for the Thin Provisioning (Thin LUN), the automatic tiering in a Storage Pool with FAST VP heterogeneous on two levels of disk technology by migrating segments (sub-LUN) 1GB, and the use of SSDs up to 2TB as second-level cache.
The concept of Meta-Lun is renewed. For the record, the Meta-LUN allows extension by stripping (for performance) or concatenated (for volume) on multiple RAID groups presented a LUN to a server. And as long at it, we just mix the two modes). Bay allows (optional product) compression - no-deduplication information, especially for static volumes such as those granted by the VTL instance.

administration Unisphere is hosted on a station built in redundant configuration. Unisphere is used through a banner menu at the top of the screen is relatively simple to understand grouped by family: Monitoring System Storage Hosts Replicas Support Settings and Configuration Wizards (wizards) simplifying navigation to perform administrative tasks for the tool being rich is just sometimes not knowing where we stand.
The System menu provides access to information about the physical and logical configuration of the storage array, the state of its components in real time, and manages the various alerts. Thus, we can centrally control all of its EMC configurations through a single point, a real plus for a user EMC. I noticed also integrated access to the Replication Manager interface directly through the menu Replicas "

The logic is always based on InfoSet - definition information characterizing the data to replicate - Activity associated with - the jobs-replication. Monitoring jobs is it done through the Data Protection Advisor for SAN & NAS which also allows the measurement of performance of the bay, the configuration change tracking and monitoring the use of the volume.
For us using friends VMware, EMC integrates a tool to act as a VCB proxy supporting NFS datastores / VMFS / SAN / RDM, which operates visibly Vaai. Besides managing your VNX, Unisphere allows access configurations RecoverPoint and compile an inventory of the infrastructure while interfacing with VMware vCenter via dedicated plug-in.

In summary, the VNX is a synthesis of all the knowledge on a bay convergent EMC SAN / NAS that meets both the needs of small SMEs with VNXe up with the very large 7500. However, even if I see much more objectively, I personally still struggling with the often detrimental effects of range when managing transitions both in terms of financial and operational and the automatic tiering really problematic for the bandwidth consumed on the back end when one is faced with highly volatile data.
