DoSTOR analysis of the store Oct. 8: In a recent New York meeting of the General Assembly SDC storage (StorageDecisionsconference), the enterprise storage administrators have said that the switch of virtualization is better than more equipment or controller of virtualization, but they recognize the virtual Of switches is not yet ripe.
in the panel discussion, from NatonwideInsurance storage architect and AlanGrantham from NewYorkStockExchange senior storage administrator PeterCarucci said they would like the intelligent switch virtualization. However, because the product is not sufficient, intelligent switches are not very mature, they also considered that the implementation of the deployment of Youdaishiri.
at the meeting, they evaluated several products, including intelligent switches on the virtual product of EMC's Invista, IBM's SAN Volume Controller (SVC) equipment, as well as the controller of virtualization products of the Hitachi TagmaStore .
manages 250TB of network storage Carucci said: I think the smart switching technology is the only way for many enterprises.
Invista currently supports Cisco and Brocade's intelligent switch. McData is expected early next year to launch its intelligent switches.
Carucci said: The intelligent switches to expand the capacity of the SVC is a lot of times. to his experience, SVC only support a maximum 560,000 times IOPS (I / O per second), and intelligent switches to support the theory, at least 2,500,000 times IOPS. Carucci also said that his company is using EMC's equipment. He said that in dealing with failure, SVC at the request of the SVC to connect to each host to install a special driver, and the drive does not support multi-path software. Invista on These will not be trouble. Brbrbr As for TagmaStore, Carucci said he was not keen on the array-based virtualization. Brbrbr He pointed out that the cache with Hitachi to achieve virtualization, through the controller to I / O. He said: A virtual disk array management of a lot of potential problems. Switch controller plays a role, but the controller is not a switch. BrbrbrGrantham from a number of insurance companies for the storage management company, the company's storage management for more than 1PB. He is looking for its virtualization product. Grantham prefer FalconStor's IPStor software, equipment, IPStor although in a In the virtual site of the data but not suitable for the entire enterprise. Compared to IPStor, Invista have to go through a longer period of time to get users to trust the test. Brbrbr He said: We have not implemented virtualization, but we will eventually achieve virtualization. I saw a Invista is the only switch-based virtualization products, if your business needs, I suggest you wait another 6 months, waiting for the switch products mature. EMC said Invista to ship before the end of the quarter, including Grantham and Carucci, including a few who have gone Invista. So far, Invista has not yet appeared in the EMC Corporation in September announced a price list. EMC said Invista is the most large-scale enterprises. Grantham and Carucci said that despite the very much hope that the implementation of intelligent switches, but they have expressed for a long time after the test, they would not recommend it. Grantham said: This is just a Released product, we will have to adopt market 6-8 months of maturity, if you want to achieve based on intelligent virtual switch, you must first test. Brbrbr
