Fujitsu Eternus DX8700 S3 Performance SAN for Virtualized Datacenters

You're looking at the Fujitsu Eternus DX8700 S3 and wondering if it's the right fit for your setup. Let's dig into the specifics, starting with performance metrics. This model offers a robust performance with its combination of SSD and HDD, allowing you to balance speed and capacity based on your storage needs. The integrated RAM cache can be configured for read and write operations, which can significantly impact throughput. You might find that under high IO workloads, its ability to utilize 32GB of cache memory helps maintain lower latency compared to other options out there. I've noticed that other platforms may offer less cache, affecting their performance when running multiple virtual machines.

You've got to think about scalability because that's essential in a data center environment. With the DX8700 S3, you can scale up as needed, adding additional disks and expanding your storage pool without much hassle. This model supports a dense configuration unit and can accommodate up to 480 disks in a single system. Compare that with something like an HP 3PAR, which also scales but might require more complex configurations at times. Having the option to scale efficiently helps as your storage needs grow. If you're anticipating rapid growth, that scalability might really sway your decision.

Looking at connectivity options is crucial too. The DX8700 S3 supports various protocols like FC, iSCSI, and FCoE, providing flexibility depending on your existing infrastructure. You want to make sure that whatever you choose integrates smoothly with your systems. If you're rocking FC and want to keep latency low, the 16Gb FC option here works great. Exploring competing products, you'll notice that some may fall back to 8Gb, potentially introducing latency issues under high load. In this case, having that advanced connectivity support might put the DX8700 S3 in a favorable position depending on what you use.

The data management features can't go unmentioned either. The Fujitsu model comes with a set of built-in features like thin provisioning and snapshots, which can save you resources both in storage and management. Thin provisioning helps you allocate space more efficiently, allowing for growth without upfront commitment. In contrast, platforms that don't offer this functionality force you to provision more than you need, potentially wasting resources. Integrated snapshots can also enable point-in-time recovery, which is essential for protecting your data, especially in case of accidental deletion or corruption.

I can't overlook the unified management console that you'll find in the DX8700 S3. It allows for centralized management across different storage solutions, simplifying operations. You can monitor performance metrics, set alerts, and configure storage settings all from a single interface. If you compare that to a more fragmented management approach in some other platforms, you'll see how time-consuming and complicated that can get. The coherence in the management can make a significant difference for IT teams who juggle multiple systems.

Performance tuning is another aspect to consider. The Eternus system allows for automated tiering, which dynamically moves data between SSD and HDD based on usage patterns. This means you can prioritize access to frequently used data, while less critical info can sit on slower disks. Some competitors depend on manual tiering, which is cumbersome and requires constant monitoring. Automating this process can save you from unnecessary headaches and time.

Then we come to redundancy and availability features. The DX8700 S3 includes components that not only run in active-active configurations but also support features like N+1 and multi-pathing to ensure that in case of component failure, your data remains accessible. This enhances reliability significantly. If you're evaluating something like a Dell Compellent, you'll find that it also provides high uptime features, but it may lack some of the more advanced multi-pathing options that you see here. You definitely want to ensure that whatever you choose can minimize downtime because any interruptions can cost you both time and money.

To wrap it up, I have to point out that you must consider your budget against the feature set. The DX8700 S3 offers a lot in terms of performance, scalability, and management features, but it might come at a price. Some alternatives might present lower initial investments but also cut back on advanced features that could save you time or improve efficiency in the long run. It's definitely a balancing act, and you should weigh the cost against the capabilities you need.
