https://community.hpe.com/t5/storevirtual-storage/vsa-help/m-p/6732558#M9186 Hi<BR /><BR />1. I realise that VSA NR10 affects write performance. But is this latency due to the network portion of the write to another host, or because it gets written to tier 1 on that second host?<BR />2. If it's the latter, what are the best ways to mitigate this? (Raid performance? Spindle count?). Is there any way for something like smartcache to help out here?<BR />3. Are there any general recommendations for which HP SSD type is best for VSA? I like the read IOPS of the value endurance, and I'm not sure the higher spec SSDs will make a big dent on write iops with the latency you get on NR10 for writes anyway, but I'd also like reassurance that their DWPD is sufficient.<BR /><BR />Any help greatly received Tue, 14 Apr 2015 20:13:42 GMT DazzaBig 2015-04-14T20:13:42Z https://community.hpe.com/t5/storevirtual-storage/vsa-help/m-p/6732558#M9186 Hi<BR /><BR />1.
