Intel DC P4510 as slog device?

[Fred974]

Hi,

I have an old Dell PowerEdge R610 with Intel(R) Xeon(R) CPU X5650 @ 2.67GHz and 72GB RAM. I Have very poor performance with NFS share. To remedie this issue I disabled sync which provide me with decnet speed but stop me from sleeping at nigh as I know things can go wrong with this setup. I am looking to add a slog drive as this seem to be the proper way to do it. I am looking at using the Intel DC P4510 NVMe drive for my slog drive. Could anyone please tell me if this drive is good/fast enough to be used as a slog drive? Does anyone know if it will work in my R610 Server (HBA) card

Thank you in advance

An Optane 900 or 905p or P1600x would be better (or a pair for redundancy)

As for whether it will work - I have no real idea as I am not familiar with the R610
You will need either:
2 * M.2 slots
1 * PCIe3*8 slot that supports bifurcation and a PCIe card for two M.2
1 * PCIe3*8 slot that does not support bifurcation and a PCIe card with a PCIe switch that supports two M.2

You need:
1. Very High Endurance - a SLOG is always written to, and in a steady state never read from
2. High Speed in comparison to the pool its on
3. PLP (Power Loss Protection)
4. Small size (a SLOG uses very little space)

Obviously an Optane would be better but I think that an 1TB Intel DC P4510 NVMe is good enough to be a SLOG.
With 1 DWPD it has the same endurance than a Seagate Nytro 3350 960 GB, that is used by iXsystems in their X-series.

To get the small size, you can use the LOG WRITE CACHE overprovision menu in /ui/system/advanced
Set 16 GB.

I cannot tell for the PowerEdge R610, but I can confirm that the Intel P4800X works in DELL PowerEdge R420.

Thank you very much for all the quick reply. I will look at both solutions.

Those RMS/8G units are great for 1Gb, not I think quite enough for 10Gb - not that they would be a bad thing - just not quite optimal. Now an RMS300/16G would be perfect for 10Gb.

I wonder if the RAM is replaceable, or if its soldered on

OP did not mention his network speed… I think these RMS-200 are great value, but for 10 GbE a 100 GB Optane P4801X may indeed be a better fit.

Of course, if the OP already owns the DP P4510 it's a fine choice, just not as good as a RMS (lowest possible latency) or an Optane.

Hi all,

I have a 10GB network sfp+. I just spent lot of time on google and it look like NVMe compatibility was introduced on 13th generation of poweredge. Look like I cannot add a slog as my I only have 2x PCI slot. 1x is used for the SFP+ card and the other is used has the SAS card to connect to the MD1200 JBOD :((

I think I will need to look for another server or accept the risk of loosing 5sec of data in worse case scenario.

Could anyone advice on a budget friendly Truenas server that will reside in a datacentre?

Sorry - but that question is more like "how long is a piece of string?"
