Product Information

Use larger SSDs, and manually partition them to do double-duty as SLOG and a small separate pool. You'll get the separate pool you want, but you're now sharing the SSDs between SLOG (a 100% write workload) and another mixed R/W workload. Optane can handle this just fine, but other SSDs tend to experience a "bathtub curve" effect under a mixed I/O load - they do great at a 100% read or 100% write, but put them in the middle at 50/50 or 70/30 either way and you'll get significantly less performance. You're also at risk because the GUI/middleware won't consider the existence of those partitions if you have to replace a drive through that method - basically, it'll be up to you to manually recreate the same partition scheme and manually resilver should a failure occur.

How to Add More PCIe Slots? - PC Guide 101

This splitter connects to x1 slot on the board and then splits into four x1 slots for further expansion. So basically, the idea here is that the amount of bandwidth the cards occupy on the splitters should not be greater than the bandwidth provided by the primary x1 host slot connected to the motherboard.I typically don't run my 1080Ti's much past 200 watts, so I have plenty of headroom when using either cable type. Again, the key is the connectors themselves being good and tight, both on the PSU end (if using a modular PSU), the 'Y' cable connection, and to a lesser extent, on the GPU end.

PCIe splitter from x16 to 2x8 or 4x4, passive. - CPUs

Each MiniPCI Express Adapter has a standard MiniPCI Express connector for plugging in the MiniPCI Express expansion add-in board (downstream). The MiniPCI Express host board connects to the motherboard MiniPCI Express connector (upstream). The PCI Express flat cable (12 inches) is used for connecting the MiniPCI Express host board and MiniPCI Express Adapter boards, and it provides a flexible connection between the MiniPCI Express expansion add-in board and the motherboard. A graphics card that didn't take up the whole x16 slot might be acceptable if it's possible to use the last channel at the same time for a 1x riser or something, don't know if that's allowed.There are many types of PCIe splitters, and they come in many configurations. The splitter above is an external PCIe splitter. Take the splitter above, for instance. So here, basically, an x4 host card splits into 4 x PCIe x16 slots. If each splitter is occupied, each connected device will be subject to the overall bandwidth provided by the x4 host slot.

So you cannot install four graphics cards on these and expect all of them to perform optimally for gaming. The performance will not even be close to optimal. Each graphics card is designed to use 16 PCIe lanes! They aren’t intended to be used on x4 slots for gaming, let alone on the 4-way split. The Splitter includes four x1 (or x4, or x16) PCI Express adapter boards with PCI Express flat ”ribbon” cables, and one x4 PCI Express host board. Having more PCIe slots means getting the opportunity to install more expansion cards for various uses. However, there are only two ways to increase the amount of PCIe slots you have: They are also great when installing multiple smaller cards like a network adapter, sound card, USB or SATA expansion cards, etc. Each of these cards utilizes only a single PCIe lane and thus would not saturate the host slot. There Are Many Types and Configuration of Splitters

On a motherboard, an x1 slot has one lane, an x4 slot has four lanes, and an x16 slot can have 8 or 16 lanes.
