The new product scans: End memory system in IBM DS5020
DS5020 is that IBM begins to supply in one section in September of this year the end stores the new products, its introduction, do not have low end products situation after remedying series IBM DS5000. Store the little introduction of manager’s money of the products according to IBM system and Greater China district of Ministry of Science and Technology, DS5020 has been promoted by more than 70% compared with DS4000 its performance, therefore suit the application demands of small and medium-sized enterprises further.
DS5020 has 4 available ports, 4 8Gb/s foreign ports, the quantity of the largest magnetic disc is 112, it can be that FC can adopt SATA plate too. Though there are only 112 magnetic discs, the back interface of the system adopts interface of 4 8GB/ses, in this case, greater than 112 magnetic discs, its systematic function will have influence, so over 112 magnetic discs, it is useless to promote instead as to systematic function. In buffering, DS5020 has offered the option that 2G, 4G buffer. Gold points out a little, in the ABC of memory system of grade, it is not obvious to add too and buffer results got up, consider the cost factor as a whole, 4GB is a good choice.
Gold points out a little, the ones that need paying attention to are: 8Gb/s twice that of 4Gbps, for store but speech, network connect bandwidth raise, magnetic disc connect bandwidth change inside the memory system, analogous to right away then of ” the door ” It is wide to change, still can’t improve the performance of the whole system. The inside design in DS5020, has put out the new port, so its whole performance is improved to some extent.
In management software, DS5000 simple compared with DS4000 in software, the intersection of interface and humanization further, operation is easier too. In addition, DS5020 has offered the dynamic RAID function, needn’t shut down, in fact RAID1 0 can change into RAID 5, can operate online directly.
