a viable option, but applications such as databases directly choose to use logical volumes to implement snapshots because they cannot be managed by snapshot technology at the file system level. In general, there is no need to implement snapshots at the application layer, which can be implemented using the underlying file system or volume Manager interface for backup mechanisms, but requires a temporary pause to ensure snapshot data consistency. In general, software-layer-based snapshots are eas

With the release of Vnx's new version of block R5.32 and file V7.1, more and more users in the marketplace are focusing on this version. But many users do not know what the new version of Vnx is all about. Therefore, professional and technical consultants will face more and more problems in this area, in order to professional and technical advisers more comprehensive and systematic answer to the relevant questions, the series will be "high efficiency", "ease of use" and "effectiveness" of the th

Article title: Sun announces the open-source Key Management Protocol. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Sun recently announced that it will open source its key management technology. The unified communication protocol between the key manager and the encryption device is a major goal of Sun's recent Open Storage initiative project. at the same ti

way, in order to ensure effectiveness, Shielding must be electronic end-to-end continuous and grounded correctly. It is also important to select an end-to-end solution when selecting a shielded cabling system. Using Hybrid components of different systems may cause problems due to impedance mismatch.Shielding system costs, including additional installation required, typically 20-30% higher than equivalent UTP solutions.Standards and rulesEMI or RF interference (RFI) refers to any unwanted signal

When Auto media management is enabled, Networker automatically recycles and labels the volume when appropriate. Avamar EMC Avamar is a deduplication backup software and system solution. It can be used as a standalone backup application, but it can also be integrated into the Networker environment as a deduplication

VVNX Professional Storage Device VirtualizationAt the World Congress, EMC announced the Project Liberty Program, which focuses on hardware and software decoupling and virtualization deployment of professional storage devices. Currently, EMC has released the VVNX virtualization Community version and provided free download links. VVNX is a virtualization-based, industry-leading VNX Array (VVNX) that enables u

nominal according to the impedance generated at a certain frequency, the impedance unit is also ohm. generally, 100mhz is used as the standard. For example, 2012b601 indicates that the impedance of the magnetic beads is 600 ohm at 100mhz.Rated current: The rated current is used to ensure that the circuit works normally. 3 difference between inductance and magnetic beads:More than one turn of the coil is used to be called the Inductance Coil, less than one turn (wire through the magnetic ring) t

virtualization has a heterogeneous premise, that is, some people's view is that there are three companies participating in the same time to make storage virtualization effective." All I have to say is, forget about this kind of talk. Even if you insist on signing with only one supplier, there is no problem. ” Compared to other it areas, the storage market is more proprietary, says Taneja. This leads to problems if you just love a storage vendor. For example, if you are an

performance advantage." For example, the more powerful the server is, the more we have the opportunity to bring a better product to our customers, however, the increasing number of server processor cores also makes it possible for terminal user to run more virtual machines on each server using the same number of devices, which can be reduced by the change in the sales performance. If we do not make adequate adjustments to the new technology development trend for solutions and products, it is li

All along, the enterprise storage products seen, when there are dedup and compression two brothers, are Dedup first, compession followed. Seems natural, but is this order necessary? Is it the best?Is this going to be a problem?In a nutshell, the hypothetical block (segment, ...) is based on the fixed length:1. Compression is CPU intensive, on the wire, no additional lookups are required, usually the size of the input cannot be too small to facilitate the discovery of pattern for improved efficie

Now the full flash array has become a Xtremio, EMC's, and Vnx-f (Rockies), IBM Flashsystem. Full Flash is truly efficient, redefining the storage speed. With the ultimate performance, high availability, you greatly improve the efficiency of enterprise-class applications. Mention the advantages of flash, then there is no doubt that speed! But behind the speed advantage, SSD faces the limit of price, capacity and life. Of course, with the development o

familiar with these protocols, you do not have to worry about them. We will discuss them in future articles. Of course, the NAS mentioned above cannot be sold. Most enterprises choose NAs from companies such as EMC and netapp because they have features that are hard to implement on common file servers. First, let's give a brief introduction. Girls should polish their eyes to see how different things are from ordinary it guys. I. High Performance. If

?As we all know, IC chip packaging SMD and double-row in the sub-type. It is generally believed that the difference between SMD and double-row is mainlyIt is different in volume and welding method, which has little effect on system performance. actually otherwiseEvery trace on the PCB has an antenna effect. Each component on the PCB also has an antenna effect, the larger the conductive part of the component, the dayThe stronger the line effect. Therefore, the same type of chip, package size is s
