As a good gland, a review of new data storage systems emc vnx

imageEMS data storage systems - it's like a good German car. You know, you're a little overwhelmed by the brand, but data security and control sensitivity are secured. Service: Premium guarantee, for example, delivery of spare parts within 4 hours of departure of an engineer if necessary.

More recently, a new line of equipment, the flagship of which allows up to 1,500 discs to be delivered at 6 PBs. Below is her review with a short CCD in principle. And a story about how really good things have done better.


I know you'll ask for the price. She's tall. You need to pay at least $30,000. This money gives a completely reversible configuration with a powerful function, three-year support and an updated sophth, as discussed below. So the system is far from home and not even for small businesses.

imageThe most important thing you get for this money is the scary words DU/DL will stop showing up in the reports. This is the worst combination for service engineers and customers. Reducing the risk of simple or loss of data is what the IT director is willing to fight by any means.

Why do you need a hybrid type CCDD?

First a little story. Multilevel storage is a combination of fast and cheap, but discs in one data set. There was an opportunity for such a combination even when we dreamed of flash discs because of their space cost.image Well, there's a myth that this thing came up to improve productivity. No! Initially, such storage has been used for savings: Put down data that are not used on slow and cheap disks. So it's gonna take a little bit more quickly, just for the data.

SSD then entered our lives very hard. It was logical to add a bit of SSD to our soup from fast and slow drives. The fastest and hottest data, only 5 to 10 per cent of the total, are now on. Updated CD VNX is the third generation of hybrids in which I believe they have succeeded in fame.

imageSo, on the one hand, we have solutions that are entirely computable and flash-modules. They work with hot data at a speed near DRAM rather than classic HDD, but such systems are very expensive when the value of the hygigabate of stored data is recalculated. Typically, they are used where the 10-20 terabite needs to be continually plunged. Example is high-loaded CBD, VDI. On the other hand, systems on classical mechanical discs do not allow the data to work so fast, but they can be stored very much (the cost of stored hygabytes may be in order below).

In most cases, however, there is a need to have a large vault at the same time and to provide quick access to the “burning” data. Examples include typical CBD tasks when some CBS should be stored at the same time as those for virtualization, mail, archives, etc.... In these cases, either Flash-SD links + classical CCBs or mixed ( hybrid) type CCBs are used. We're talking about the last ones today, supporting both flash-cop and classic disks in the same system.
