![]() ![]() "No channel partner should sell a server without this," he said. When the data is retrieved, instead of using how the data is laid out by the array, customers get improved performance from a more logical layout."ĭiskeeper 15 Server is available, and lists for about $400 per physical server, Morin said. "We've seen the benefits of having data writes laid down in a defragged manner. "In logical volumes, there is some benefit to laying down the tracks in a more logical fashion," he said. So a couple years ago, we moved customers to Condusiv's V-locity product line, but it's seven times as expensive as Diskeeper."įor some environments, Diskeeper 15 Server provides the benefits of V-locity, Taylor said. "In SAN and virtualized environments, there's no benefit to use Diskeeper," Taylor told CRN. Plan B Technologies, which installs a copy of Diskeeper on every server that is not connected to a SAN to keep the disks defragged, plans to bring Diskeeper 15 Server to its SAN customers, said Steve Taylor, chief technology officer of the Bowie, Md.-based solution provider. Fragmentation is a problem with SAN storage. Other great apps like Condusiv Diskeeper are Auslogics Disk Defrag, AVG PC TuneUp, PrimoCache and UltraDefrag. The best alternative is Defraggler, which is free. Condusiv Licensing Condusiv Diskeeper v.18.0 Professional - Upgrade License - 1 License - Price Level (3000-4999) license - Academic, Volume - PC Less. "It doesn't change the blocks on the storage device," he said. There are more than 10 alternatives to Condusiv Diskeeper for Windows, Mac and Android. "If Windows sees a contiguous file, it just needs a single I/O to manage it."ĭiskeeper 15 Server defragments files at the logical layer, but doesn't touch data at the physical layer, Morin said. "If you defrag at the logical layer, performance increases," Morin said. So SAN performance degrades over time."Įven when a SAN does a good job of managing disks at the physical layer, Windows doesn't see data as a single file, but instead sees multiple logical reference points within a file, each with its own I/O characteristics, Morin said. But logical disks are fragmented before the SAN can see them. Windows addresses the disk at the logical layer. "The Windows operating system doesn't see the physical layer of the disk. "But fragmentation of disks at the logical disk layer usually gets missed," he said. While technology for defragmenting individual disk drives has been in use for years, Condusiv is the first to apply the concept to SAN storage with Diskeeper 15 Server, said Brian Morin, senior vice president of global marketing for the Burbank, Calif.-based vendor.ĭiskeeper 15 Server was designed to go beyond the technology SAN providers offer to maintain storage performance, Morin told CRN.įragmentation and SAN performance is addressed by the SAN vendors, but only at the physical layer, Morin said. Condusiv has added a new twist to its Diskeeper line of disk defragmentation software by tackling for the first time the question of how to defragment SAN storage.
