Fighting the Storage Fear Factor

Henry Newman — Tue, 01 Sep 2020 00:00:00 +0000

Using fear to sell products is nothing new in any industry, of course, and storage users, there are questions you need to ask to ensure that you are buying hardware and software that meet your business objectives at a fair price, and even more importantly, that you’re not buying a dead-end product, which will raise […]

Get Ready for RAID-6

Henry Newman — Tue, 01 Sep 2020 00:00:00 +0000

It was not all that long ago that RAID-6 was just some theoretical RAID level in books that was not implemented by vendors. RAID was expensive, and the cost of adding an extra parity drive was pricey. And since RAID reconstruction was relatively fast, given disk performance compared to density (more on this later), RAID-6 […]

Checking RAID Performance There are two parts of RAID controllers to consider to ensure they can meet the performance requirements of RAID-6 compared to RAID-5, since almost every midrange RAID vendor has designed its controller around RAID-5 performance requirements rather than RAID-6. One is the performance of the processor calculating the parity, and the second […]

Strategic Storage Budgeting

Henry Newman — Tue, 01 Sep 2020 00:00:00 +0000

With the price per gigabyte of storage coming down rapidly, that line item is no longer the overriding consideration for most storage budgets. While that is some relief for storage users, in other ways it creates a new problem: how long should you wait for storage to get faster and cheaper before you buy? Before […]

The Importance of Data Restoration

Henry Newman — Tue, 01 Sep 2020 00:00:00 +0000

I recently responded to an emergency at a customer site. The customer had an important database that had gotten corrupted that it proceeded to restore from backup tapes. The customer has a good backup policy, yet it still took six days to get back online. Your backup is only as good as your ability to […]

Storage Horizon 2008

Henry Newman — Tue, 20 Jul 2010 00:00:00 +0000

It’s time once again to look back on the storage predictions I made a year ago and look ahead at what might be in our storage future for 2008 and beyond. Enterprise Storage Forum’s Henry Newman reviews how accurate his 2007 predictions were and weighs in on where he thinks storage is headed in 2008. […]

Are Linux File Systems Right for You?

Henry Newman — Tue, 20 Jul 2010 00:00:00 +0000

Potential customers with high I/O requirements frequently ask me if they can use Linux instead of AIX or Solaris. Linux file systems aren’t for everyone. A variety of limitations make them poorly suited for large and HPC environments. Unsure About an Acronym or Term? Search the ServerWatch Glossary No one ever asks me about […]

Linux File Systems, Revisited

Henry Newman — Tue, 20 Jul 2010 00:00:00 +0000

My article three weeks ago on Linux file systems set off a firestorm unlike any other I’ve written in the decade I’ve been writing on storage and technology issues. Contrary to popular opinion, Linux file systems will require changes to handle the 100TB environments that will become commonplace in the not-too-distant future. Unsure About an […]

RAID’s Final Countdown

Henry Newman — Tue, 20 Jul 2010 00:00:00 +0000

The concept of parity-based RAID (levels 3, 5 and 6) is now pretty old in technological terms, and the technology’s limitations will become pretty clear in the not-too-distant future — and are probably obvious to some users already. In my opinion, RAID-6 is a reliability Band Aid for RAID-5, and going from one parity drive […]
