Wish you could have the best of both worlds sometimes? Most do. Dell EqualLogic recognizes the fact that some organizations just might have “those kinds of networks” that contain both low-end data (e.g. file data) but also some high-end applications and databases that must never go down as they push the highest thresholds of IO data known to man. For these types of networks where one would need multi-tiering in a single array, Dell EqualLogic has answered with the PS6500ES and the PS6510ES.

In both 1 Gigabit (PS6500ES) and 10GigE (PS6510ES) flavors, these iSCSI SAN units will contain seven (7) 400GB SSD drives and forty-one (41) 2TB NL-SAS drives, issuing close to 85TBs worth of raw capacity. Dell EqualLogic says, “…these hybrid arrays bring you auto-tiering that keeps your hot data readily accessible on low-latency SSD drives and your colder data on high-capacity, near-line SAS drives (NL-SAS), all within one array. For tiered workloads, the PS6510ES can process up to 360% more IOPS with 75% reduced IO average latency when compared to PS6510-X.”

EqualLogic pricing for these units will be available later today for these units, and each must come with a 3-, 4-, or 5-year ProSupport (Next Business Day, Non-Critical 4-Hour, or Mission Critical) package. So whether you have some very high transactional databases or demanding media applications, data warehousing needs, or even a large virtual desktop infrastructure (VDI), the Dell EqualLogic PS6500ES and / or PS6510ES arrays can consolidate those multi-tier workloads into one single iSCSI storage array. And as with any other EqualLogic arrays, these units come standard with all of the advanced software and storage features from the start.

You may have noticed that Dell’s new EqualLogic SAN product line no longer contains the traditional SATA drives most often reflected in the past “E” series like the formerly active PS4000E, PS5000E, and PS6000E series. The newer generation of EqualLogic – such as the PS4100E, PS4110E, PS6100E, PS6110E, PS6510E and other EqualLogic “E” product lines – now contains the Nearline SAS drives, more commonly termed NL SAS.

So, why the move away from SATA to NL SAS?

In general, NL SAS drives are built to address more of the enterprise-level storage environments and applications. NL SAS tends to have a higher MTBF (Mean Time Before Failure) rate, averaging about 1.2 million hours MTBF, and it tends to be just as cost effective from a cost per Gigabyte perspective as a traditional SATA drive would be.

While the NL SAS drives tend to come in flavors of 5.4K and 7.2K RPM drives, they are known to “(combine) the head, media, and rotational speed of traditional enterprise class SATA drives with the fully capable SAS interface typical of 10K/15K RPM SAS drives.” Essentially you’re getting the best of both worlds (SATA and SAS). Plus, compared to SATA drives, the interface is about 30% faster as well.

Faster drives…better cost…more uptime and reliability…? Sounds like a recipe for EqualLogic iSCSI SAN success if you ask me. EqualLogic pricing is available on all EqualLogic SAN models, including those with NL SAS for both Gigabit and 10GigE arrays.

With the new release of PS Firmware Revision 5.1, Dell introduced more advanced data management options. At the core are 3 load balancing layers that ensure high-performance while balancing capacity value. This post describes the 3 layers and how they can be applied.

EqualLogic Load Balancers in PS Series Pools

When you initialize the first array and create a PS series group, a default pool is automatically established. After adding an array to the group, it is referred to as a member of the group. All members are initially placed into the default pool, and administrators subsequently deploy volumes from this pool. It is within a pool that resources such as network bandwidth, disk capacity, and I/O are balanced automatically. Multiple pools can be created to isolate volumes and separate members. This may be done for a variety of reasons, including technical (e.g. placing specific application data on resources such as SSD) or business reasons (e.g. ensuring that legal department data is isolated from the data from other departments.) With more than one pool administrators can initiate moving volumes or members between the pools seamlessly, with no downtime to the applications. Within a pool, Dell’s EqualLogic PS Series is designed to automate the placement of data to maximize the utilization of the resources that the customer has chosen for their SAN.

There are three load balancers that operate within a pool:

  • The NLB (Network Load Balancer) manages the assignment of individual iSCSI connections to Ethernet ports on the pool members
  • The CLB (Capacity Load Balancer) manages the utilization of the disk capacity in the pool
  • The APLB (Automatic Performance Load Balancer) manages the distribution of high I/O data within the pool.

NOTE: Dell End-of-Life policies may change over time. Please refer to your specific equipment warranty and replacement policies.

Every six to nine months or so, Dell EqualLogic will release a new EqualLogic product line. Heck, some of you might even still have an EqualLogic PS300E or PS5000E. Out with the old and in with the new…right?

Well, not necessarily!

That’s the beauty of an EqualLogic iSCSI SAN solution. You don’t have to tear out, rip-out-and-replace, or forklift upgrade your storage area network (SAN) every time there is a new model release. Remember that old PS50E or PS100E? Keep it! The EqualLogic iSCSI SAN architecture is built to add and expand what you currently have to the newer models (there may be some limitations reaching back more than 5 years or across certain architectures). But for the most part, you can virtually “glue” members together and extend their useful life.

So, when EqualLogic announces an “End of Sale” on their current product line, it simply means that they’re phasing into the new product line and that the old product line (at the time of this writing, the EqualLogic S4000, PS6000, PS6010, PS6510, and PS6500 series) will no longer be actively sold or positioned.

But please note that support for these products will continue based on their End-of-Life plan, usually 3-5 years, sometimes more. Best advice? Keep up with your ProSupport contracts through Dell EqualLogic. Get these renewed each and every year to maximize your value.

So, keep that old EqualLogic array in your network…and buy that new one, virtually add it to your existing group or use the old one to replicate to…either way, it’s still good.

Going to a Gigabit Ethernet network from a 10/100 Ethernet network (Remember those days…?) was fairly easy. But if you think a migration to 10GigE is going to be just as easy, think again…

Don’t get me wrong. I’m all for getting more juice to the network, and the Dell EqualLogic iSCSI SANs come in a variety of 10GigE flavors. But before you jump into buying that 10GigE EqualLogic SAN you found on the self-service EqualLogic Pricing website, let’s share a few strategies that may help you maximize your Gigabit Ethernet network right now before taking the plunge into 10GigE.

1) Do you really need the extra bandwidth…?
2) What applications are driving the need to move in this direction…?
3) What kind of 10GigE interfaces are you looking to support…? And do you have the right connectors and cables to support this…? (fiber vs. copper, Cat 6a or better cables, etc.)
4) Have you looked into the cost of 10GigE NIC cards for your servers and other hardware on the network that may need this…?
5) Do you need more than 10 meters distance from the array…? (10GigE SFP limit)
6) Do you have the dough for all of this…?

So, now that you’ve justified the cost for a 10GigE network and have been eyeballing that cool EqualLogic PS6010E, PS6010X, PS6010XV, or PS6510E array from the EqualLogic Pricing website, here’s the cool stuff:

  • Dual 10GbE iSCSI controllers with two (2) SFP+ per controller
  • All the same inherently advanced features you’ve come to love and respect through an EqualLogic SAN
  • Complete redundancy
  • Installation in under one hour

Sure, fibre channel has had 10Gig for years now…but can you install it in under one hour, have all of the advanced features embedded onto the array from day one and still have the same (if not better) performance than fibre channel…? No, I didn’t think so either…

Well, you tell me. You and / or your company have just invested more money in an EqualLogic SAN than the cost of your own vehicle. Heck, probably several vehicles. In other words, you’ve invested – or are about to invest – a lot of money into a premium EqualLogic iSCSI SAN solution…a solution that actually does what it says it’s gonna do. So, yeah, you need ProSupport…but now a couple of questions arise:

What kind of ProSupport do I need…and how much does EqualLogic Support Cost?

Okay, let me break it down for you.

There are two major types of ProSupport – Mission-Critical (MC) and Next Business Day (NBD). From these two options, you have a choice between 1, 3, 4 or 5 years of ProSupport when you initially purchase your EqualLogic SAN in addition to different response times (2-hour, 4-hour, 6-hour).

So which do you choose…? Simple. Listen closely…actually, read closely…

Mission-Critical – select this option for one or multiple reasons:

  1. The EqualLogic SAN will be placed in a location where there will be no technical staff available to physically manage it
  2. Your organization has true mission-critical applications that rely heavily upon the EqualLogic SAN being up always…you know, the kinds of applications you’d get a pink slip for if they ever go down
  3. You simply need the peace of mind that someone will show up within two or four hours with spare EqualLogic parts and a red cape to come and save the day and fix it for you
  4. Your company can afford it, you have some free money (let’s talk…I can help you here…ha!) and / or your company simply has a business requirement that all applications be serviced with mission-critical support agreements
  5. Lack the technical confidence of changing out hot-swappable parts and would rather allocate just a bit more time on “other” projects

Next Business Day – select this option for one or multiple reasons:

  1. None of the above reasons under Mission-Critical really apply
  2. The location where the EqualLogic SAN is to be located is surrounded with technical gurus
  3. Your technical confidence and competence is through the roof
  4. You really don’t have the money for Mission-Critical…but, hey, don’t worry about it…most companies are in this spot as well…
  5. You like to get your hands dirty and exercise those technical skills once in a while…trust me, swapping out hot-swappable parts and configuring a SAN in under 20 minutes can be hard work…

That’s really just about it. But don’t forget…we have EqualLogic Pricing available through our self-service pricing model to give you the options. Honestly, Dell doesn’t do this…you know what they do…? They tuck the cost of ProSupport in with the cost of the array…we don’t do that, we give you ProSupport choices and break it out through our EqualLogic Pricing model. Give me a call or email…I’ll explain it all that ProSupport stuff to you from what’s in it, the differences, etc. All of it.

And, oh, there’s another reason why you need ProSupport. Dell requires it. Yup, that’s right…

Okay, so you tell me you need an EqualLogic iSCSI SAN SAS array. But do you really need a SAS array…? I mean, do you reeeeeeeally need a SAS array…? Let’s look at the facts and see if what you have and what you need match up…fair…?

There’s no doubt that you’ve heard that SAS is fast, right? Oh, yeah. In fact, EqualLogic SAS units are extremely fast and have been known (and documented) to even outperform their fibre channel counterparts. Take that, fibre channel!!!

The SAS EqualLogic iSCSI SAN units can come in 10K or 15K RPM drive speeds within the EqualLogic PS4000X, PS4000XV, PS6000X, PS6000XV, PS6010X and PS6010XV models. For the EqualLogic PS6500X and PS6510X models, only 10K RPM drive speeds are available…for now.

So, let’s take a look at what you have. Hmmm…you have some file data and maybe some Exchange and SQL. Yes, database applications are usually pretty demanding and may merit faster drive speeds…SAS would definitely do the trick…

However…

Have you done a perfmon yet…? What’s a perfmon you might ask…? It stands for Performance Monitor (perfmon), and it’s a tool that helps you assess the (storage) traffic on your network. It’ll show you how many IOPS (Input/Output Operations Per Second) your network is pushing through, where your peak traffic times are and all that good stuff. Federal Appliance happens to coordinate these for free for our clients in an attempt to more accurately assess which EqualLogic iSCSI SAN you might need…whether it’s a SAS or a SATA.

Rule of thumb?

If your IOPS are more than 600 or so, you might want to consider a SAS unit. If it’s under this, you might be better off staying with a SATA unit. Why pay for more horsepower than your network really needs…? SAS does cost more…about 20% to 40%, on average, but if you don’t need it don’t buy it. I have plenty of clients running multiple database applications in their environment across an EqualLogic SATA unit…and it’s more than enough for them. Every client is different.

But there are other circumstances that might drive the need for an EqualLogic SAS unit over a SATA one…such as file size, imaging requirements, disaster recovery, replication needs, additional database applications, SAP implementations, ERP implementations, Oracle, DB2, clustering, future growth, and so on.

Still not sure with EqualLogic SAN is right for you…? Neither am I…heck, that’s why we need to talk. Now. Until we discuss your requirements and assess your traffic with a perfmon or some other network tool, we really won’t know for sure. But knowing what you need will help you build a business case for that EqualLogic SAN you’ve always wanted. You know, that nice new EqualLogic PS6000XV-9.6TB array that those financial tightwads in upper management declined last year…? Well, now you’ve got ammo…so go ahead, buy that PS6000XV-9.6TB…we’ve got your back…

EqualLogic, with its all-inclusive enterprise-class iSCSI SANs virtualized storage arrays, enables IT administrators with the technology and tools to build out affordable and easily manageable business continuity and disaster recovery solutions. With built-in snapshot, replica, clone, and replication features, along with partnerships with industry leading technology partners, EqualLogic simplifies the planning, deployment, and maintenance of an IT infrastructure that ensures that your business is fully protected and always operational.

BC/DR has traditionally been necessary, but too complex and expensive

Disaster recovery beyond backup was not affordable for most organizations when Fibre Channel SANs were the only option. Complex configurations including communication network extension equipment, add-on software, and staff training has been prohibitively expensive. Recent compliance regulations (e.g., HIPAA, Sarbanes-Oxley, and SEC rules) have pressured organizations of all sizes to make more data quickly recoverable for longer periods of time; company files, databases, and e-mail must be restorable for years. And with the proliferation of 24X7 business operations, companies of all sizes are recognizing the requirement to have a complete business continuity and disaster recovery environment to ensure that their IT operations are completely protected against natural and unnatural disasters and outages.

With storage consolidated on EqualLogic PS Series arrays, business continuity and disaster recovery is now affordable, fast, and simple. EqualLogic iSCSI SANs leverage your existing IP based LAN and WAN networking assets and competencies without requiring any add-on software or costly staff training. The PS Series’ Auto-Replication capability, standard in each array, provides point-in-time periodic replication to multiple remote sites. This method, easy to set up and operate, delivers multiple restore points and application-consistent copies that can be restored in minutes.

Ever wonder what all the suffixes on the Dell EqualLogic PS Series arrays mean? For existing customers that have been working with them forever (we’ve been providing EqualLogic solutions for over 5 years now) the migration from the original “E” model made sense. The latest “XVS” spawned this blog post…this is getting a bit confusing!

Here are the prefix summaries for those that are just getting familiar with the units:

“E” – SATA drives running at 7200 RPM
“X” – 10,000 RPM Serial-Attached SCSI (SAS) drives (various capacities exist)
“XV” – 15,000 RPM Serial-Attached SCSI (SAS) drives (various capacities exist)
“S” – Solid-State Drives
“XVS” – SAS and Solid-State hybrid boxes

While most customers choose “E” arrays for more static, less critical data, don’t underestimate their performance. The striping and caching intelligence that is built into the units means you will get outstanding performance regardless of drive type.
