A Deeper Dive into Solid State Storage
Yeah, there’s some hype out there about solid state storage (SSS). No, I take that back…there’s a TON of hype out there around solid state storage. Why? Well, let’s take a look at some of the benefits of solid state drives (SSD) and where they might be used:

  • The main, primary benefit of using SSD over a spinning disk (HDD) is direct access
  • SSD flash memory does not require seek time (HDD does), resulting in higher transaction rates (IOPS) than HDD
  • An example of SSD vs HDD in IOPS:
    * 100 to 200 IOPS for HDD vs. 5,000 to 10,000 IOPS for SSD
  • A flash disk (SSD) can provide 40x better IOPS than a spinning disk (HDD)
  • SSD performs typically performs better for random workloads than sequential workloads
  • SSD read performance will typically be better than the write performance
    * SSD read speeds are normally 2x that of its write speeds
  • The cost per performance for SSD is much better for SSD (though the cost per TB is much better for HDD)
  • Power consumption for SSD is much better:
    * An SSD might use 1 watt while a HDD might use 10 watts
    * The power performance of an SSD is typically 1000s of IOPS/Watt vs. the performance of an HDD with only 10s of IOPS/Watt

Dell EqualLogic’s Answer to Solid State Storage and SSD
Does EqualLogic do SSD…? Of course! Dell EqualLogic is still the leader in the native iSCSI SAN marketplace, and EqualLogic pricing will reveal that it can do SSD in either a full SSD or a hybrid SSD solution:

1 Gigabit Ethernet

  • EqualLogic PS6100S-4.8TB (24x200GB SSD drives)
  • EqualLogic PS6100S-9.6TB (24x400GB SSD drives)
  • EqualLogic PS6100XS-13TB (7x400GB SSD with 17x600GB 10K SAS drives)

10GigE

  • EqualLogic PS6110S-4.8TB (24x200GB SSD drives)
  • EqualLogic PS6110S-9.6TB (24x400GB SSD drives)
  • EqualLogic PS6110XS-13TB (7x400GB SSD with 17x600GB 10K SAS drives)

Frankly, it doesn’t make sense. EqualLogic has been shipping product for almost ten (10) years now and is the undisputed leader in pure iSCSI SAN solutions in the entire industry. But if you’ve been an EqualLogic SAN client for a number of years now, you want to ask yourself a few questions before you even consider looking beyond an EqualLogic SAN:

  • Have I kept my ProSupport agreements current, renewed, and up-to-date?
  • Have I brought my EqualLogic arrays up to the current code?
  • Have I updated my EqualLogic arrays with any and all appropriate security patches?
  • Have I reached out to my local EqualLogic rep or spoken with my EqualLogic reseller in the past six (6) months for the purpose of getting a technology refresh on EqualLogic?
  • Have I reached out to my noted team above for a Dell EqualLogic roadmap presentation for new products and / or features that will enhance my business environment?

Let’s face it, we’re all busy…and you’re right, that’s no excuse for not hearing from your Dell EqualLogic team. However, you bought your EqualLogic SAN for a reason…perhaps multiple reasons. One of the hot topics nowadays is the issue of integrated backups into your SAN, so before going down that road here are some questions to ask in regard to this (taken from Dell’s own product positioning team):

  • Do you want to risk losing your backups if the primary storage has a bug or there’s a human error?
  • If your backup and recovery solution is poor, how will you easily find a particular file to recover and restore it?
  • What kind of data is taking up the most space?

Thinking about expanding your EqualLogic SAN…? Updated EqualLogic pricing is available and now easier to configure than ever before.

Okay, so you’re an SMB (Small to Mid-Sized Business) with a pretty good idea of how much capacity you need, and you’ve also determined that you’re going to go 10GigE for your storage and computer network.

So, of course you’ve done some research and found that Dell offers the perfect solution in their EqualLogic PS4110 series…great! Now the hard part: Deciding which one to buy. Well, here’s a basic breakdown for you to help you decide:

Model Value Proposition Differentiation
PS4110E Low entry price point

Lowest $/TB in the PS4110 line

Highest capacity arrays in the PS4110 line

Capacity-oriented NL-SAS

12, 24, 36 TB (12 HDD)

7,200 RPM NL-SAS 3.5”

PS4110XV 3.5” Balance of cost, performance and capacity for enterprise data centers High-performance and Capacity SAS

7.2TB (12 HDD)

15K RPM SAS, 3.5”

Remember, you can only have two (2) PS4110 in a single group or logical SAN. This means that you can even have a PS4110E-36TB array in the same group as a PS4110XV-7.2TB where you dedicate your lower-end traffic to the PS4110E and your higher-end (database) traffic to your PS4110XV.

EqualLogic pricing for these units prices these very aggressively, even without any discounts…and with ProSupport plans spanning three, four, or even five years long, these 10GigE iSCSI SAN units can go a long way in providing the SMB with capacity and feature-rich SAN functionality for years.
