    <title>topic Cache Write Pending in Disk Enclosures</title>
    <link>https://community.hpe.com/t5/disk-enclosures/cache-write-pending/m-p/3491341#M15410</link>
    <description>Hi there.&lt;BR /&gt;&lt;BR /&gt;Need someone to enlighten me on this storage paramaeter. On my storage system I observe a constant 10% cache write pending, but occasionally it spikes to abt 20%. Some question puzzling me :&lt;BR /&gt;1. What is write pending? Is it data from Host waiting to be written to the storage cache or data on storage cache waiting to be written onto disks?&lt;BR /&gt;2. What is controlling the amt of cache for write pending ? If the storage cache allocated for write pending is limited to 10%, does it equates to IO from hosts have to wait if the 10% is full ?&lt;BR /&gt;3. Is there any technical documents giving more details on this topic (no brochure pls).&lt;BR /&gt;&lt;BR /&gt;Thanks.. Appreciate if anyone can help.&lt;BR /&gt;&lt;BR /&gt;LAI</description>
