Brocade's purchase of Foundry Networks seems like a smart move, but technology acquisitions in general and storage acquisitions in specific never seem to pay off well. OK, never is a bit extreme, but it does seem rare and failure here hurts everyone. It distracts the buying company, often ruins the software from the bought company, and leaves users hanging in the balance.
Cloud Storage Migrations
Finishing up the migration series, let's talk about how you would migrate out of a storage cloud. With public storage clouds in particular, this can be a critical issue. These services are all in their infancy. What if you pick the wrong one, how can you get your data back?
In my last entry on migration migraines we discussed the challenges of moving from one primary storage provider to another and went through a few solutions. One of the best methods to make migrations easier is to keep the amount of data on primary storage at a minimum, but what do you do about archives that will grow to petabytes in size?
Moving data between tiers of storage has gotten easier as a result of global file systems and simplified archive software, but upgrading to a new platform ... that is just plain ugly.
Tier 4, The End Of The Trail Of Tiers
Tier 4 once was the simplest of all tiers -- it was just tape. The advent of disk-to-disk backup, which has helped most backup strategies, actually has made the tier itself more complex. I also can take a stand that, in some ways, the introduction of disk has made the process of backup itself more complex.
Revealing The Laughably Low-Tech Video Set-Up At 'The Daily Show'
As technologists, we're prone to fall in love with the latest new technology. We think we require the most powerful PCs, the fastest networks, and the smartest smartphones to get our jobs done. But The Daily Show reminds us that we can achieve excellence even when our tools are woefully out-of-date.
The Death Of Storage Hardware
My former boss, who is still a mentor today, had a saying: "Success in life is the elimination of variables." Words to live by and words that the storage community must have heard. The biggest variable they deal with when installing a solution into their environment is the variable of, well, their environment.
Oh, Tier 3...
Remember about five years or so ago when life was simple? We had fast SCSI and Fibre Channel drives for data and we had tape for backup. Seemed perfect. Then came the ATA-based drives, and you were told to move your older data to them and start sending backups to disk. Then powering the data center and storage in particular became a problem; another use for ATA, put them in stand-by mode, spin them down, put them to sleep, and then eventually turn them off. As is usually the case, the hardware i
Tiered storage can be difficult to manage and one of the challenges to its acceptance is the amount of effort it takes to move data between those tiers. We've written about several methods to move data between tiers in previous blogs, but in some cases the decision isn't that complicated.
Tiered Storage Redefined
In the never-ending world of tiered storage, it really breaks down into two types of storage; transactional (active) and passive storage. For obvious reasons these two worlds overlap, but it is surprising how many levels of granularity there are within these tiers. Gone are the days of three tiers. There are more tiers of storage than ever, so it's helpful to see where we are.
Data retention and archiving aren't just for large enterprises. Small to medium-sized businesses need to be concerned about e-mail retention, data retention, and data archiving. I know the first response is, "We are not a public company, we don't have to worry about that." You might be right, but the need to retain and store e-mails and other forms of data goes well beyond being a public company. While I won't go into all the reasons why, here are some simple ones:
What Is Short Stroking And Why Should You Care?
As the major storage vendors start rolling out the Solid State Disk solutions, you're going to hear a term that you may not have heard for a while, if ever; short stroking. Short stroking a drive is a method to format a drive so that only the outer sectors of the disk platter are used to store data. This practice is done in I/O-intensive environments to increase performance.
Disk-Based Archive - Ready For Prime Time
The drumbeat is being heard. A recent survey commissioned by Permabit Technology generated some interesting results. While almost every answer creates interesting blog material, the stats that jumped out at me were that almost 25% of those surveyed are managing more than 100 TB of primary storage and that 43% of those surveyed were paying $25 to $40-plus per gigabyte for that primary storage. These stats make it quite clear -- you can't afford not to archiv
