Migration Relief

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?

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 from one primary storage platform to another is a fact of life. New suppliers will continue to emerge which offer compelling advantages over your current supplier, or new technologies altogether such as solid state disk may cause the need to change primary storage suppliers. The answer as I have written about is to move inactive data off primary storage as soon as you can. Keeping primary storage small not only keeps costs in line, it also makes migration between platforms easier by keeping the data set small.

The potential pitfall of aggressive archiving is that the capacity of that archive will and should get very large over time. Archives of 50 terabytes to 100 terabytes will become commonplace and over the next five or six years, PB-sized archives will not be uncommon. Data sets of this size not only make migration impossible; they make tasks like backup a challenge. Does this invalidate the disk archive concept? No. Growth is inevitable. You have to choose where you want that growth to happen and a platform to deal with that growth. As I stated in a prior post on the potential cost savings of archives, you want to grow your storage in the area where it costs the least and that area is the archive. How, then, do you deal with large archives? You need to design the archive to be a permanent fixture in the data center. The answer is scalability, massive scalability. This is where "real" archive solutions come into play, systems that were designed from the ground up to provide archiving as opposed to dense, cheap RAID boxes.

Companies like Copan Systems and Permabit all have systems that can scale close to 1 PB and both will exceed that number as drive capacities continue to grow. They get there differently. Copan Systems uses densely packed power-managed drives, while Permabit uses grid architecture to offer scale. The point is that they both can scale, offer key redundancy capabilities, and offer functionality that will routinely check the health of the data and drives in the system. They are designed for long-term retention of data. Even with all this scalability, technology will continue to march on. The ability to upgrade these architectures without moving data is going to be critical and is something for you to pay attention to. This is something that cloud storage may seem ideal for and a topic we will address tomorrow. I am participating in a Cloud Storage 101 Webinar this coming Wednesday at 3 p.m. EDT.

Published: 2015-02-27
The dns-sync module before 0.1.1 for node.js allows context-dependent attackers to execute arbitrary commands via shell metacharacters in the first argument to the resolve API function.

CVE-2015-0655
Published: 2015-02-27
Cross-site scripting (XSS) vulnerability in Unified Web Interaction Manager in Cisco Unified Web and E-Mail Interaction Manager allows remote attackers to inject arbitrary web script or HTML via vectors related to a POST request, aka Bug ID CSCus74184.

CVE-2015-0884
Published: 2015-02-27
Unquoted Windows search path vulnerability in Toshiba Bluetooth Stack for Windows before 9.10.32(T) and Service Station before 2.2.14 allows local users to gain privileges via a Trojan horse application with a name composed of an initial substring of a path that contains a space character.

CVE-2015-0885
Published: 2015-02-27
