Spectra is going to break an unspoken rule: “What happens in your data center, stays in your data center.” Organizations are notoriously secretive about what happens in their data centers. This is understandable. Data drives the operations of most organizations, and is sometimes considered the secret sauce of operations, possibly a competitive advantage. Likewise, discussing the exact means of data protection would possibly give the bad guys insight into vulnerabilities to be exploited. And if nothing else, it’s sometimes hard to shine a light on something that cost your organization time and money. Read More

Words matter… so do acronyms. We’ve seen a new category of storage management software developed which is being referred to as, you guessed it, “Storage Management Software.” Some have questioned whether this is something new or if it is just another offering of HSM (Hierarchical Storage Management). There are differences between the two categories. This isn’t just about product positioning or marketing; it’s about what certain products do or don’t do and whether or not they are a fit for your data center or a specific need. Both solution types are designed to keep frequently accessed data on the fastest storage (usually the most expensive and least dense) while moving inactive data to slower storage (usually much less expensive and significantly more dense). How the solutions accomplish this is very different. Read More

In my last blog, I discussed types of “data movers” including backup, archive, HSM and migration. These are ways to move data, but where are you moving the data to? Disk? Tape? Cloud? A combination of those? The significance of “data mover” applications to an organization’s workflow is closely tied to other elements of their data storage ecosystem, namely storage targets.

Over time, storage targets have evolved from repositories completely “unaware” of the data they hold to hyper-intelligent data management platforms. On one end of the spectrum, more typically found in tier-1 storage, are Storage Area Networks (SANs). These repositories, which are unaware of the data they hold, offer up blocks of storage which a server’s file system or a database administrator must configure into usable storage. With the advent of Network Attached Storage (NAS), storage devices use their own processing power and file system to lay data across blocks – presenting the storage as a folder of files which can be accessed by multiple servers, and even servers with varying operating systems and/or file systems, across the network. SAN and NAS are commonly found in tier-1 data storage, although they can be used in tier-2 storage as well. Read More

It’s 1985. You’re the last one to leave the office that afternoon. You go into the server room, put the 8-inch floppy disk in the drive, go back to your office, type a backup command via the “terminal” on your desk, and now you’re free to go home. Your data is being backed up and safe. One last thing… don’t forget to take yesterday’s backup floppy with you in case the building burns down over night. OK, maybe you worked for a slightly larger company than I did in 1985, but it worked pretty much the same.  There was storage and backup for the storage. We didn’t refer to “primary” storage.  Disk was storage and all floppies, CDs, or tape was backup to that storage. Read More

1. Solid State (Flash): NAND flash, or solid-state storage, is currently the fastest growing technology in the storage market. On the high end, flash is gaining ground for database applications. On the low end, flash is rapidly replacing small hard disks and is considered the de facto technology for digital cameras, smart phones, tablets, laptops and desktop computers.

Pros:

• Reliability – Flash contains no mechanical parts and produces less heat than HDDs.
• Performance – It allows for high speed data transfer to and from storage media.

Cons:
