Data compression startup Storewiz has picked up $9 million in funding, underlining growing interest in alternatives to de-duplication technology. (See Storewiz Secures $9M and Data Compression: The Squeeze Is On!.)
The startup's story revolves around its ability to compress data as it travels from a server to a back-end array. By spreading the workload across multiple CPUs, the vendor claims to improve existing compression ratios for databases as well as CIFS and NFS files. (See Storewiz Bolsters Compression, Storewiz Intros STN-5000, and Storewiz Intros Product Line.)
Storewiz is touting this technology as an alternative to data de-duplication, which reduces the bulk of backed up data by compressing data that appears in more than one place. (See EMC Talks Disk & De-Dupe, NetApp De-Dupes, De-Dupe Deep Dive, Dealing With De-Dupe Doubts , and Analysis: Data De-Duping.)
The key difference with Storewiz, which made it onto the most recent Byte and Switch list of top 10 startups, is its ability to deal with all types of storage traffic. (See No Presto Change-o.) That comes from compressing data on the fly, as it travels from switch or server to storage.
In contrast, other vendors in this space, such as EMC, Asigra, and Symantec, compress data on a server before it is sent to backup. A third group, including FalconStor and Sepaton, compress data outside the data path, after it is written to the target disk. (See Sepaton Scores $22M.)
