Synology’s Active Backup for Business is a powerful, license-free backup tool included with many of their higher end “plus” and rackmount NAS units. Here is my latest video taking a look at its integration with VMware vSphere and ESXi. I walk through installation, setup, backup and restore.
In short, it is an excellent tool that provides features you’d expect to see from enterprise “paid” backup solutions. For those with home labs or smaller environments, it makes the value proposition of buying a Synology NAS much more enticing!
In my previous post, I got the hardware all setup on the DS1621+ test unit that Synology was gracious enough to loan me. Today, I’ll be doing some of the initial storage configuration in preparation for getting iSCSI configured for use in my vSphere lab.
But first, I’ll need to get some flash storage added to the NAS.
I’ve got three Crucial MX500 1TB drives that I’ll be removing from my TrueNAS box for testing in the DS1621+. Although they are getting a bit dated, they are still solid performing SATA SSDs. Don’t forget to properly remove your LUNs/Datastores!
Installing the 2.5-inch drives is an easy job. Four small screws attach to the back of each sled and hold the drives in the correct position.
With all six drive bays populated, we’re ready to begin getting the storage prepared for use on the DS1621+.
Creating Storage Pools
The first thing that needs to be done before you can use the drives is to create one or more storage pools. This is where you group disks and apply a RAID level to them. When clicking the Create button, you’ll be greeted by the storage pool creation wizard.
You’ll first be prompted to use classic RAID levels or to use Synology’s Hybrid Raid or SHR. SHR makes the creation of a pool easier, but its best feature is the ability to make use of all disk space when disks of different sizes are in the pool. Traditional RAID levels can waste a lot of space in this type of situation. It is great for beginners, but we’ll stick with the classic RAID-levels.
A new 6-bay AMD Ryzen powered NAS unit from Synology with lots of potential!
My very first commercial NAS box that I bought over 13 years ago was the dual-bay Synology DS207+. At the time, it was the cream of the crop. The hardware was great, but Synology’s very rich software suite was what really set it apart from many of its competitors at the time. The unit served me very well for years in my home network.
Once I got my first VMware home lab setup, I moved away from consumer-grade NAS units and toward more powerful custom-built servers running FreeNAS/TrueNAS. Although awesome for home use, the SoC (system on a chip) ARM-based processors on these old units simply couldn’t handle the I/O requirements for VMs on iSCSI or NFS datastores. Unless you were willing to shell out a lot of dough for an enterprise-grade NAS/SAN, you were stuck building your own. A lot has changed in this market over the last few years. NAS units have gotten much quicker and a reasonably priced unit can now be a very feasible solution for a wide variety of applications – including virtualization. Today, Synology makes a number of multi-bay NAS units with powerful processor options. They have everything from high-performance ARM based units to Xeon-Ds and even AMD Ryzen Embedded options as in the 1621+. Although they still command a premium price, you get way more for your dollar today than you did even just a few years back. When Synology asked if I would be interested in trying out one of their business class “plus” NAS units, I jumped on the opportunity.
Synology was kind enough to send me a review sample including a DS1621+ NAS unit, three of their Synology branded 8TB hard drives and their new E10G21-F2 10Gbps SFP+ NIC. Over the next few weeks, I hope to take a look at this latest generation of multi-bay NAS systems and see how feasible they are for a small to mid-sized business network. I’m also very interested in trying out some of Synology’s included software that is catered towards VMware vSphere. For now, I just wanted to share a quick unboxing and hardware setup post.
Power Consumption: 51W (Access), 25W (HDD Hibernation)
Warranty: 3 Years
The specifications for this NAS unit are quite impressive. The one feature that gets most people excited is the embedded AMD Ryzen processor. With AMD’s hugely successful Zen architecture, this is not surprising. AMD has managed some very impressive performance numbers – especially in their 3rd and 4th generation CPUs. Being an embedded part, the Zen V1500B processor is a little different than their desktop processors. From what I can see, it is based on AMD’s first generation Zen architecture so it won’t be quite as potent clock-for-clock as some of AMD’s recent Ryzen CPUs. None the less, with four cores, eight threads and a 2.2GHz clock speed, this is a very capable CPU for a NAS. Best of all, being an embedded part, the total TDP for this processor is only 16W. Having a potent x86-64 CPU under the hood opens up the possibilities for a number of different use cases. Not only should iSCSI storage performance be up to the task, but you could even run virtual machines and many of the more demanding software packages on the NAS unit.
Another great feature is Synology’s inclusion of NVMe. Three and a half inch mechanical drives do still have their place for affordable raw storage capacity, but flash storage is really necessary for good performance. All six drive bays support 2.5 inch SATA SSDs, which is great, but there are now two NVMe slots intended to be used for drive caching as well. Being able to use multiple storage tiers and caching really gives this NAS a lot of performance potential.
Without further ado, let’s check out the DS1621+ and the other goodies Synology sent over.
Synology moved away from flashy packaging years back. I like the subtle cardboard packaging because it lets the quality of the product speak for itself.
The size of the box makes the NAS unit feel larger than it actually is. There is ample protection from shipping damage with foam protecting the unit from all sides. The NAS itself is wrapped in plastic to keep dust out.
A small cardboard box includes a pair of high quality ethernet cables and a standard power cable. A small bag of screws and the drive bay keys are also contained within. From what I can see, the screws are only needed for mounting 2.5-inch drives.
The unit itself has a heavy, high quality feel to it. The outer shell and back panel are metal and only the front panel and drive bays are constructed of plastic. Six hotswap SATA drive bays are accessible from the front of the unit. Two 92mm fans dominate the back and line up perfectly behind all six drive bays and should provide good directed airflow.
There are two USB3 ports at the rear (and one at the front) as well as four 1GbE NICs and a pair of eSATA connectors. The eSATA ports can be used for Synology’s expansion units. With two DX517s, you could have up to 16 drives in total.
Synology was kind enough to include three of their self-branded 8TB HAT5300 mechanical drives with the NAS unit. From what I can see, these are manufactured by Toshiba and are 7200RPM models. Synology supports a large number of mechanical drives from a variety of manufacturers, but supplying their own removes the guess work that customers need to do and guarantees 100% compatibility.
Since I plan on using this NAS in my VMware home lab, 10GbE networking will be essential. Synology provided me with their brand new E10G21-F2 SFP+ card. Synology supports a pretty long list of 10Gbps NICs on some of their older NAS units, but the list is short for the DS1621+ at this time. I suspect they are still testing cards for compatibility as this NAS is still quite new. Similar to their branded HDDs, going with a Synology branded NIC ensures 100% compatibility. Synology sells 10Gbase-T models as well if you aren’t using SFP+ DACs or optics.
