(HDS???s) RAID 400 subsystem on which<BR />the HDS Freedom Storage Lightning 9900, announced in June 2000, is also based (see Gartner<BR />FirstTake "Hitachi Data Systems Takes Storage Specification Lead with Lightning 9900"). However,<BR />HP has succeeded in differentiating its product through proprietary microcode features and<BR />management software that improve the XP512's performance in HP/UX environments."<BR /><BR />I noticed that the software provided by HP and by HDS are under different name , but I don't think the content are different too...<BR /><BR />does anybody know some specific diffences between HP512 and HDS 9900?<BR /><BR />Thanks a lot in advance.<BR /><BR />Margaret<BR /> Thu, 03 Jan 2002 20:01:14 GMT Margret Liu 2002-01-03T20:01:14Z https://community.hpe.com/t5/disk-enclosures/difference-between-hds9900-and-xp512/m-p/2638632#M3699 Hello everyone:<BR /><BR /> I will apprieciate if anyone can tell me if there are differences between HDS9900 and XP512.<BR /><BR /> HP claims that "The XP512 is based on Hitachi Data Systems???
