understand that money is hard to come. Working under the guidance of the new project manager, I lost "freedom", as if he was always watching me, and my work began to get busy, I often have some messy things for me to do, but I can't talk about working overtime. I started to do new projects. Over the past two months, this project is almost over, waiting for EMC and reliability testing, I learned a lot of technical things. In fact, this is also quite g

Work: Vplex ============================== EMC vplex is the next-generation solution for block-level virtualization and data mobility within, Alibaba SS, and between data centers. EMC vplex provides storage Federation by aggregating storage arrays that can be located either in a single data center or multiple data centers. vplex is also used as the data mobility solution for environments like cloud

core business uses the hardware netapp/emc and san Optical Fiber architecture. For resource data storage and video, sas or solid state ssd disks are used. If the data is too large, you can use the hotspot shard storage method: for example, the most frequently accessed 10-20% uses ssd storage, and the 20-30% in the middle uses sas disks, the last 40-50% can use cheap sata. Layer 7: If the design of tens of millions of PV sites is reasonable, one or tw

Recently, fiber channel manufacturers Emulex and Brocade have released reports that their hardware products can work with EMC Clariion AX100 storage arrays. According to Gartner's survey, small and medium-sized enterprises are expected to account for 5 billion of the disk storage market worth $ 20%. Roger W. cox said that 70% of small and medium-sized enterprises still rely on direct attached storage, which is a good opportunity for storage vendors to

The most recent it event that people have been focusing on is Dell's acquisition of EMC. While it's still too early to say how Dell will integrate EMC, the acquisition will undoubtedly improve Dell's overall capabilities in enterprise-class solutions. Several acquisitions have also proven that Dell has "two brushes" in acquisitions and consolidations, such as the acquisition of EqualLogic and Compellent, wh

EMC acquires video storage device vendor Isilon systems to improve EMC's weaknesses in the distributed Scale-out Architecture NAS Technology, which has been consistently recognised by customers in recent years in media, big data and HPC scenarios, and last year and another product line Povital Hadoop launches a data lake solution that addresses the processing and storage needs of customers for semi-structured and unstructured data under the wave of th

So want to become a good engineer, need to grasp the integrity of the system and understanding of the existing circuit, in other words, give you a circuit diagram you can finally see how much,If you don't understand 80% or more, you are far from being a good engineer. The second is the circuit debugging ability and the ability to review the map, but the most basic ability or schematic design PCB drawing, logic desig

At EMC World 2015, it was announced that ScaleIO 1.32 could be downloaded for free in a non-production environment. This free version of the download is called drictionless (ff) Download version. As follows: Http://www.emc.com/products-solutions/trial-software-download/scaleio.htm Then you may ask, what is the production environment? EMC spends such a big price to buy Scaleio, everybody is so free to use u

interference and the ability of the system itself to intercept external electromagnetic interference. For the latter, Europe has passed the EMC standard for electromagnetic compatibility testing. The general method of shielding is to mask the metal on the outer layer of the connected hardware to filter out unnecessary electromagnetic waves. There are two kinds of shield lines with different structures: STP and SCTP. (2) shielding system defects A. gr

The/data DIRECTORY needs to be resized due to production, from the original 90 GB to 190 GB, increasing the space by GB.The production environment is a RHEL server, and the backend is connected to the EMC storage through an optical fiber switch. First, RAID the idle hard disk on the EMC storage, divide the LUN, and map it to the production RHEL server.(Note: the premise of this expansion is that the partiti

If your vnxe system does not have an Internet connection, you can obtain system license files from a computer that has an Internet connection and upload them to the VNXE system. To obtain and activate the VNXE system license: The task you need to complete is to get the Vnxe product ID, and you can vnxe the system's 14-bit product ID/SN on the label on the back of the system. 1, from a computer with Internet connection, use a Web browser to open the

group is a mail-enabled Active Directory group object that contains all the recipients of the properties in Active directory that match the group filter. If you modify the recipient properties to match the filter, the recipient may inadvertently become a group member and begin to receive messages sent to the group. It is important for an administrator to define the filter criteria to reduce the chance of such problems occurring. New Distribution Group: Generally speaking, the distribution gro
