But one analyst has expressed doubt that it will appeal to a wide section of its target audience. They have exposed a very limited set of capabilities that this architecture is capable of says Arun Taneja an analyst at the Taneja Group. They re not very elaborate in places that matter. IBM offers only one configuration with SATA disk drives Fibre! Channel ports and six iSCSI ports. Besides offering just one version Taneja says the product literature lacks any reference to some of the high end features required by next generation Fibre Channel storage systems. For example IBM doesn t specify clearly enough whether XIV has a clustered controller design Taneja says. As described last October in a Taneja report Next Generation Fibre Channel Storage Systems Market Forecast clustered controller design offers more than two active controllers on a storage volume and synchronises the cache across all active controllers. In addition to supporting multiple active controllers clustered systems virtualise the individual controllers and make the entire set of controllers appear as one single storage system to hosts wrote Taneja. Taneja does expect clustered controller design and other next generation features to appear in future versions of the XIV product. I believe the architecture has these features but IBM didn t feel comfort! able presenting them to the market yet he said. XIV s chairman was Moshe Yanai who used to be EMC s head of engineering and was the chief architect behind Symmetrix. EMC s chief strategy officer for the Symmetrix line Barry Burke took special delight in criticising IBM s XIV release on his blog Tuesday.
